Would you buy a second-hand car from this man?

.

The patent for a time machine has been filed with the United States Patent and Trademark Office by one Dr. Marvin B. Pohlman of Tulsa, Oklahoma. Here is the abstract of his submission:

.

“The method employs sinusoidal oscillations of electrical bombardment on the surface of one Kerr type singularity in close proximity to a second Kerr type singularity in such a method to take advantage of the Lense-Thirring effect, to simulate the effect of two point masses on nearly radial orbits in a 2+1 dimensional anti-de Sitter space resulting in creation of circular timelike geodesics conforming to the van Stockum under the Van Den Broeck modification of the Alcubierre geometry (Van Den Broeck 1999) permitting topology change from one spacelike boundary to the other in accordance with Geroch’s theorem (Geroch 1967) resulting in a method for the formation of Godel-type geodesically complete spacetime envelopes complete with closed timelike curves.”

.

 

Dr Pohlman asserts that by creating an artificial spacetime wormhole in his laboratory, he has a working time machine. Yeah, right…

.

Well, that looks fairly straightforward, doesn’t it? Eish! On what basis did the patents clerks decide that this was a real thing? A cursory glance at the abstract reveals just what pie-in-the-sky bulldust it really is. Singularites are physical impossibilities, and certainly have never been created or seen. Pohlman suggests that he can create two of these things in his lab, and then keep them nice and still while he beams an electron stream at them. Ably assisted by a green elephant, no doubt. And it gets worse! The manic gobbledegook spirals down into the most unbelievable claptrap about point-masses changing topology in spacetime envelopes. This is pure LSD stuff.

.

The website Before it’s news.com carried the story, and added this fascinating piece of garnishing:

.

“Some armchair Internet scientists have made a connection between Pohlman and an infamous personage named John Titor. Who is John Titor?

.

“John Titor is the pseudonym of a person who claimed to be a time traveler from the year 2036. He appeared in Internet chatrooms and on message boards for a few months back in the winter of 2000 to 2001.” [John Titor – Time Traveler]

Titor amazed and entertained hundreds of physicists and IT experts. He asserted he came from the future to accomplish a mission in the past. On his way back he stopped off in 2000 for several months to visit with his young parents and younger self in Florida. His younger version was only a toddler in 2000.”

.

Of course, having come from the future, Titor could titillate us with definite stories about what was going to happen in the years immediately post-2000. These were not prophecies, they were accounts of what he had allegedly experienced.  These include: That there will be no more Olympic games after 2004, that civil war would be breaking out in America after the 2004 election, and that CERN would create miniature black holes in 2001.

.

The time machine used by Titor, supposedly made by GE in 2036. Sure looks hi-tech, doesn’t it? Duh!

.

 Nice, Titor! Nought out of three is about what I’d expect you to get. But the pertinent point is that this abject failure to verify his story did nothing to dent the dedication of his followers. We just didn’t understand him properly, they assure us.

 

Getting the picture? The significant point here is that Pohlman’s patent application was accepted. This, it would appear, is the principle upon which Nobel Prizes are now awarded.

.

And what a damned shame that is!

Tony Carnie’s articles (“We’re losers if we don’t save the planet”, The Mercury August25, “City must aim to be low carbon”, mercury August 24) must not go unchallenged. The near-hysterical doom warnings by the IPCC (Intergovernmental Panel on Climate Change), with active support by the UN and now also many misled governmental bodies, is becoming a new dogma based on false science and misleading information. It is all blamed on an innocent little trace gas, carbon dioxide.

In Australia, enforcement of the draconian “carbon footprint” will result in the closure of 18 coal mines and the loss of 25 000 jobs (The Chemical Engineer Feb. 2011.), all for an illusion! Draconian sacrifices and penalties are proposed, some already enforced, - particularly for the developing nations. Here are some facts and considerations about climate change:

  1. US and UK Government agencies have reported a global temperature increase (so far as these can be reasonably measured) of only 0.7 degrees Celsius since the year 1900.
  2. Sea level rise has been a steady 6-7 inches (15-18cm) for the last 5000 years. More recently this figure has been 18 cm per century since 1850 (S. Goreham, Climatism, 2010). Compare this with the Dryas Cold period +- 10 000 years ago when temperatures rose by 6 degrees in a decade.
  3. The “plight of the polar bears” an “emotive poster child” of the alarmists (such as Al Gore, Michael Mann,  James Hanson and many others –perhaps we should add Kumi Naidoo?) is untenable. Polar bear populations have more than doubled since 1950 (Goreham, 2010). During the Ordovician-Silurian and Jurassic-Cretaceous glacial periods atmospheric CO2 content, now blamed for global warming, was +- 4000 and 2000 ppm by volume (H. Schreuder, 2011, “Slaying the Sky Dragon”). The present CO2 content is only 390 ppm. Where was the runaway greenhouse effect that should have followed?  At present the sun is in slumber, with sunspot activity at a 100 year low (BBC 2009). This suggests an oncoming cooling period, as in the little ice age (+- 1300 to 1850 AD) when the sun was similarly quiet. This led to the extinction of the Vikings in Greenland and many other tragedies. We have more to fear from global cooling than from mild warming.
  4. Carbon dioxide (CO2), made the principal scapegoat by the “climatists” is a mere trace gas (390 parts per million in the atmosphere), vital for all plant life through photosynthesis. Increasing the CO2 content to only 600 ppm would double the rate of tree growth, as quite simple experiments have shown.
  5. The earth’s temperature has cycled through colder and warmer periods throughout its existence. The main driving forces are due to the Milankovich cycles (from periodic variations in the earth’s orbit, tilt and rotation –long term cyclic variations), variation in radiation intensity from the sun and interaction of the solar wind with cosmic radiation (short term), and variations in the Pacific and Atlantic sea current decadal oscillations. These are large, slow deep-sea flows.
  6. The Vostok ice cores from the Antarctic, showing CO2 and temperature variations over 420 000 years, confirm that earth warming always precedes CO2 rise in the atmosphere. This is of course expected since the oceans act as a vast sink or source –(they contain about 50 times as much CO2 as the atmosphere (Hertzberg, 2011)). When surface layers warm up, CO2 is released and shows up a few hundred years later as an increase in the atmosphere. The converse happens when the earth cools, as in the numerous ice ages, i.e. CO2 starts decreasing only after cooling due to natural causes. Al Gore’s interpretation was a perversion of the truth.
  7. The Antarctic sea ice has been slowly increasing for the last 30 years.  This huge continent holds 90% of the world’s ice. Earth is in fact entering a mild cooling cycle. Moreover, the Arctic ice cap (with a miniscule amount of ice) “stopped shrinking and grew larger in both 2008 and 2009” (Goreham, 2010).
  8. Pronouncements from the IPCC (an essentially political body) should be viewed with the gravest skepticism. In–depth analyses of the IPCC’s  simplified computer model, (on which they base their alarmist predictions), by a number of scientists, specialists in the field and not connected to any industry or government, have shown that the model is untenable and indefensible. (Slaying The Sky Dragon-Death of The Greenhouse Gas Theory, 2010). Climate modeling is extremely complex. The IPCC’s model, on which they base their dire predictions, is shockingly simplified: Their earth is a flat non-rotating disk (instead of a sphere) with no poles and continuous (24hr) sunshine. It neglects heat conduction, cloud effects, variation in solar intensity, convection currents, and is based on unreliable data. (T. Ball, 2011). In any case, more than 95% of the atmospheric CO2 is from natural causes.
  9.  Who pray are the “tiny but powerful elite” (dissidents) at whom Naidoo’s ire is directed? The concerned authors I have quoted above have no connection with Industry or Governmental bodies. The real powerful elite are the UN and IPCC officials who have benefited hugely from the billions now diverted for an illusion, who all have much to lose if the climate bubble should burst, as it must eventually.
  10. The notorious Michael Mann “hockey stick” curve of global warming, it appears, was a deliberate fraud perpetrated on the unsuspecting. The Medieval Warm period (960 -1300AD) and the following little ice age (1300-1850), both injurious to their theory, were neatly excised from the actual temperature records. In 1300 AD global temperature was at least as high as, and perhaps higher than, it is today but without man-made CO2. How come? The deception was embarrassingly revealed in the “Climategate” scandal at East Anglia University in 2009. More than 1000 e-mails and documents were intercepted and posted on a Russian server and quickly disseminated worldwide -doing us all quite a favour. Temperatures had been deleted or inserted into the actual data to hide the medieval warming and little ice age periods! Similar scandals occurred in New Zealand and Australia.

I am not, of course, in favour of any pollution- particularly the mess we are making of our oceans, or releases of real pollutants such as SO2, nitrogen oxides etc. into the atmosphere. But spending billions chasing the CO2 mirage through false science is unpardonable. It is damaging to the reputations of the many earnest and dedicated scientists who labour to improve our understanding and knowledge of the world we live in. The good news is that, to quote Steve Goreham again, the “trickle of skepticism in 1990 has become a raging river today. The global warming petition project provides a list of more than 31 000 US based scientists who disagree with the theory of man-made global warming.”

The pioneers who tamed electricity had an exciting ride, and the picture became much more enticing once the intimate relationship of electricity with magnetism came out of the closet. Halfway through the 18th century, Benjamin Franklin was magnetising and demagnetising iron bars by subjecting them to an electrical current. 70 years later, the accidental arrangement of a compass needle and an electrically charged wire at an evening lecture by Danish physics professor Hans Orsted provided the first experimental evidence of the dynamic relationship between the two phenomena. By subsequent investigation Orsted was able to show a principle of profound importance to our understanding of the universe, and indeed, to the dazzling acceleration of man’s advance into an era of high technology. He observed that a freely suspended magnet tended to curl around an electrical conductor, in other words, that an interaction between electric current and a magnetic field produced rotation. It wanted to spin! Quite by chance, Orsted had stumbled upon the principle of the electric motor. And then came Faraday.

English chemist and physicist Michael Faraday was one of the most luminous scientific thinkers of the 19th century, and amongst many other achievements, became famous as a founding father of electromagnetism. He had endured a deprived childhood as the son of an itinerant Geordie blacksmith, and received only the rudiments of education. At 14, he was apprenticed to a London bookbinder. This, for Faraday, was an opportunity to read, and read he did. An early edition of the Encyclopaedia Britannica taught him the basics of electrical theory, and before long Faraday was building electrical apparatus at home. The die was cast; this was the foundation of a life-long dedication to the experimental method in science.

Using the deductions of French physicist André Ampère that Orsted’s magnetic field formed what amounted to a cylinder around the electric wire, Faraday built the world’s first rudimentary electric motor. By surrounding a conductor with an enveloping magnetic field, he got the conductor to rotate. It was revealed to be a universal principle: An electron stream wrapped in a magnetic field equals spin. In 1831, by a stroke of genius, he reversed the process. By rotating a copper disk in a magnetic field, he produced a continuous electrical current, a phenomenon known as the dynamo effect. Michael Faraday had thus demonstrated also the operation of the first electric generator. This was the second great principle: Spin a conducting material in a magnetic field and you get a stream of electrons—an electric current. His experiments clearly showed the dynamic symbiosis between electricity and magnetism, and revealed to the world how that interaction could get things spinning or conversely, how spin produced the electrical response.

Electromagnets, created by winding an electric wire around an iron bar, had been produced since the 1820’s, and they demonstrated tangibly that a circulating electrical current—a helix—would produce a magnetic field. We will learn shortly how Kristian Birkeland demonstrated in his laboratory that a magnetic field could create a visible, functioning helix in plasma. Not even the superluminal vision of Michael Faraday could have foreseen how profoundly those two principles would change our world and, ultimately, the way that we understand the cosmos. James Clerk Maxwell bound these elements of natural law together in a mathematical formalism, thereby giving the world the electromagnetic theory of light, and the equations with which technology could drive us into the space age. In a few words I have described an intellectual adventure of immense and enduring importance to mankind, one that gave to the world what are arguably amongst the most useful and resilient principles in the history of science.

The picture is this: We have a web of magnetic force fields criss-crossing the deep sky, and into it surge endless clouds of electrically charged plasma. Electricity meets magnetism. What do you think happens next? That’s right, the plasma rotates. It twists and turns and rolls, and organises itself into fantastic electromagnetic tendrils called filaments. Plasma dominates the observable universe. Most of what we can see in the cosmos is plasma, concentrated in the stars and spread throughout gaping interstellar voids. The Sun is covered in an ocean of plasma, part of our atmosphere known as the ionosphere is plasma, and so are the aforementioned auroras and even everyday bolts of lightning. There is plasma in fluorescent lighting tubes and the structure of metallic crystals. The Solar System is suffused with plasma in the form of solar winds. It is all around us, and must therefore surely be the richest and most fertile field of investigation for any physicist. It is certainly one of the most accessible. What is plasma, and why is it so special? Let’s backtrack a bit.

Nobel laureate Irving Langmuir coined the name “plasma” for the phenomenon that he studied in General Electric’s laboratories. To Langmuir, the dynamic behaviour of ionised hydrogen gas when exposed to electrical and magnetic fields was enthrallingly lifelike, particularly in its ability to organise into working subsystems. All of these plasma pioneers found a common underlying principle of immense importance to the extrapolation of our plasma knowledge to the cosmos—it is scale invariant. That is, plasma behaviour in the laboratory is the same as plasma behaviour in galaxies and beyond, for as far as we can see. If we see consistent shapes in partial vacuums in the laboratory, and the same intricate shapes again repeated endlessly in the partial vacuum of space, then we would be foolish—or impossibly stubborn—not to make the connection. We cannot exaggerate how potentially useful that makes plasma science to astronomers. Now all we’ve got to do is get them to use it!

It was Alvén’s predecessor, the visionary Norwegian experimentalist Kristian Birkeland who first looked at the cosmos with electric eyes. The great strength of both Birkeland’s and Alfvén’s work lay in the experimental foundation of their theories. Birkeland was able to deduce the operating principles of the auroras from lab work he had done with cathode rays in partial vacuums. He noticed a correlation between sunspots and auroral excitement. From that he deduced (correctly) that the rays causing the auroras were emanating from the Sun, and that they consisted of streams of electrons.[1] Further, he reasoned, the preference for polar regions shown by auroras suggested that the shimmering charged particles were somehow linked to the Earth’s magnetic field. Birkeland is today most famous for noticing that electric currents in plasma spiral into twisted, corkscrew shaped streams that now bear the name Birkeland currents, and which are seen in every corner of the sky.

There is structure and form in plasma, and sometimes it is striking. Because plasma has been studied so carefully, both inside the laboratory and out, we know and recognise plasma structures everywhere. Understanding those structures and their functions is crucial to any extrapolation we make from a terrestrial environment to the cosmos at large. A key formation is called a double layer. When a voltage potential exists across plasma, it causes freed electrons to flow through it in the form of an electric current. Now here’s the interesting part: In lab experiments, the current in a plasma-filled glass tube forms a barrier roughly half way along. It is a concentration of the strongest electrical fields, and acts as a natural capacitor—storing electrical force for later discharge. Double layers are now recognised ubiquitously in space plasmas, and we shall see shortly how they affect the behaviour of stars.

Double layers are associated with exceptionally strong z-pinches. The converging streams at that scale are easily powerful enough to compress matter lying between them to densities high enough to form cohesive planetary structures and even stars. In fact, this is probably the way that galaxies evolve, and if we get a more accurate picture of what galaxies actually consist of, it makes a lot more sense. Far from being tightly packed conglomerations of stars, galaxies are in reality very sparsely populated by anything solid. On his website, Professor Don Scott provides a much more realistic definition. A galaxy is, in the words of Dr Scott, “A vast formation of plasma clouds that contain electrical currents and occasional, widely distributed tiny lumped points of matter called nebulae, stars, and planets.”[2] Apart from being a steadfast empirical scientist and professor in the field of electrical engineering, Don Scott is also a very enthusiastic amateur astronomer. You know, the type of person who actually looks at what he talks about. My kind of man.

I received a letter from a reader the other day. It was handwritten in crabbed penmanship so that it was very difficult to read. Nevertheless, I tried to make it out just in case it might prove to be important.

In the first sentence, he told me he was majoring in English Literature, but felt he needed to teach me science. (I sighed a bit, for I knew very few English Lit majors who are equipped to teach me science, but I am very aware of the vast state of my ignorance and I am prepared to learn as much as I can from anyone, however low on the social scale, so I read on.)

It seemed that in one of my innumerable essays, here and elsewhere, I had expressed a certain gladness at living in a century in which we finally got the basis of the Universe straight.

I didn’t go into detail in the matter, but what I meant was that we now know the basic rules governing the Universe, together with the gravitational interrelationships of its gross components, as shown in the theory of relativity worked out between 1905 and 1916. We also know the basic rules governing the subatomic particles and their interrelationships, since these are very neatly described by the quantum theory worked out between 1900 and 1930. What’s more, we have found that the galaxies and clusters of galaxies are the basic units of the physical Universe, as discovered between 1920 and 1930.

These are all twentieth-century discoveries, you see.

The young specialist in English Lit, having quoted me, went on to lecture me severely on the fact that in every century people have thought they understood the Universe at last, and in every century they were proven to be wrong. It follows that the one thing we can say about out modern “knowledge” is that it is wrong.

The young man then quoted with approval what Socrates had said on learning that the Delphic oracle had proclaimed him the wisest man in Greece. “If I am the wisest man,” said Socrates, “it is because I alone know that I know nothing.” The implication was that I was very foolish because I knew a great deal.

Alas, none of this was new to me. (There is very little that is new to me; I wish my corresponders would realize this.) This particular thesis was addressed to me a quarter of a century ago by John Campbell, who specialized in irritating me. He also told me that all theories are proven wrong in time.

My answer to him was, “John, when people thought the Earth was flat, they were wrong. When people thought the Earth was spherical, they were wrong. But if you think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together.”

The basic trouble, you see, is that people think that “right” and “wrong” are absolute; that everything that isn’t perfectly and completely right is totally and equally wrong.

However, I don’t think that’s so. It seems to me that right and wrong are fuzzy concepts, and I will devote this essay to an explanation of why I think so.

First, let me dispose of Socrates because I am sick and tired of this pretense that knowing you know nothing is a mark of wisdom.

No one knows nothing. In a matter of days, babies learn to recognize their mothers.

Socrates would agree, of course, and explain that knowledge of trivia is not what he means. He means that in the great abstractions over which human beings debate, one should start without preconceived, unexamined notions, and that he alone knew this. (What an enormously arrogant claim!)

In his discussions of such matters as “What is justice?” or “What is virtue?” he took the attitude that he knew nothing and had to be instructed by others. (This is called “Socratic irony,” for Socrates knew very well that he knew a great deal more than the poor souls he was picking on.) By pretending ignorance, Socrates lured others into propounding their views on such abstractions. Socrates then, by a series of ignorant-sounding questions, forced the others into such a mélange of self-contradictions that they would finally break down and admit they didn’t know what they were talking about.

It is the mark of the marvelous toleration of the Athenians that they let this continue for decades and that it wasn’t till Socrates turned seventy that they broke down and forced him to drink poison.

Now where do we get the notion that “right” and “wrong” are absolutes? It seems to me that this arises in the early grades, when children who know very little are taught by teachers who know very little more.

Young children learn spelling and arithmetic, for instance, and here we tumble into apparent absolutes.

How do you spell “sugar?” Answer: s-u-g-a-r. That is right. Anything else is wrong.

How much is 2 + 2? The answer is 4. That is right. Anything else is wrong.

Having exact answers, and having absolute rights and wrongs, minimizes the necessity of thinking, and that pleases both students and teachers. For that reason, students and teachers alike prefer short-answer tests to essay tests; multiple-choice over blank short-answer tests; and true-false tests over multiple-choice.

But short-answer tests are, to my way of thinking, useless as a measure of the student’s understanding of a subject. They are merely a test of the efficiency of his ability to memorize.

You can see what I mean as soon as you admit that right and wrong are relative.

How do you spell “sugar?” Suppose Alice spells it p-q-z-z-f and Genevieve spells it s-h-u-g-e-r. Both are wrong, but is there any doubt that Alice is wronger than Genevieve? For that matter, I think it is possible to argue that Genevieve’s spelling is superior to the “right” one.

Or suppose you spell “sugar”: s-u-c-r-o-s-e, or C12H22O11. Strictly speaking, you are wrong each time, but you’re displaying a certain knowledge of the subject beyond conventional spelling.

Suppose then the test question was: how many different ways can you spell “sugar?” Justify each.

Naturally, the student would have to do a lot of thinking and, in the end, exhibit how much or how little he knows. The teacher would also have to do a lot of thinking in the attempt to evaluate how much or how little the student knows. Both, I imagine, would be outraged.

Again, how much is 2 + 2? Suppose Joseph says: 2 + 2 = purple, while Maxwell says: 2 + 2 = 17. Both are wrong but isn’t it fair to say that Joseph is wronger than Maxwell?

Suppose you said: 2 + 2 = an integer. You’d be right, wouldn’t you? Or suppose you said: 2 + 2 = an even integer. You’d be righter. Or suppose you said: 2 + 2 = 3.999. Wouldn’t you be nearly right?

If the teacher wants 4 for an answer and won’t distinguish between the various wrongs, doesn’t that set an unnecessary limit to understanding?

Suppose the question is, how much is 9 + 5?, and you answer 2. Will you not be excoriated and held up to ridicule, and will you not be told that 9 + 5 = 14?

If you were then told that 9 hours had pass since midnight and it was therefore 9 o’clock, and were asked what time it would be in 5 more hours, and you answered 14 o’clock on the grounds that 9 + 5 = 14, would you not be excoriated again, and told that it would be 2 o’clock? Apparently, in that case, 9 + 5 = 2 after all.

Or again suppose, Richard says: 2 + 2 = 11, and before the teacher can send him home with a note to his mother, he adds, “To the base 3, of course.” He’d be right.

Here’s another example. The teacher asks: “Who is the fortieth President of the United States?” and Barbara says, “There isn’t any, teacher.”

“Wrong!” says the teacher, “Ronald Reagan is the fortieth President of the United States.”

“Not at all,” says Barbara, “I have here a list of all the men who have served as President of the United States under the Constitution, from George Washington to Ronald Reagan, and there are only thirty-nine of them, so there is no fortieth President.”

“Ah,” says the teacher, “but Grover Cleveland served two nonconsecutive terms, one from 1885 to 1889, and the second from 1893 to 1897. He counts as both the twenty-second and twenty-fourth President. That is why Ronald Reagan is the thirty-ninth person to serve as President of the United States, and is, at the same time, the fortieth President of the United States.”

Isn’t that ridiculous? Why should a person be counted twice if his terms are nonconsecutive, and only once if he served two consecutive terms? Pure convention! Yet Barbara is marked wrong—just as wrong as if she had said that the fortieth President of the United States is Fidel Castro.

Therefore, when my friend the English Literature expert tells me that in every century scientists think they have worked out the Universe and are always wrong, what I want to know is how wrong are they? Are they always wrong to the same degree? Let’s take an example.

In the early days of civilization, the general feeling was that the Earth was flat.

This was not because people were stupid, or because they were intent on believing silly things. They felt it was flat on the basis of sound evidence. It was not just a matter of “That’s how it looks,” because the Earth does not look flat. It looks chaotically bumpy, with hills, valleys, ravines, cliffs, and so on.

Of course, there are plains where, over limited areas, the Earth’s surface does look fairly flat. One of those plains is in the Tigris-Euphrates area where the first historical civilization (one with writing) developed, that of the Sumerians.

Perhaps it was the appearance of the plain that may have persuaded the clever Sumerians to accept the generalization that the Earth was flat; that if you somehow evened out all the elevations and depressions, you would be left with flatness. Contributing to the notion may have been the fact that stretches of water (ponds and lakes) looked pretty flat on quiet days.

Another way of looking at it is to ask what is the “curvature” of Earth’s surface. Over a considerable length, how much does the surface deviate (on the average) from perfect flatness. The flat-Earth theory would make it seem that the surface doesn’t deviate from flatness at all, that its curvature is 0 to the mile.

Nowadays, of course, we are taught that the flat-Earth theory is wrong; that it is all wrong, terribly wrong, absolutely. But it isn’t. The curvature of the Earth is nearly 0 per mile, so that although the flat-Earth theory is wrong, it happens to be nearly right. That’s why the theory lasted so long.

There were reasons, to be sure, to find the flat-Earth theory unsatisfactory and, about 350 B.C., the Greek philosopher Aristotle summarized them. First, certain stars disappeared beyond the Southern Hemisphere as one traveled north, and beyond the Northern Hemisphere as one traveled south. Second, the Earth’s shadow on the Moon during a lunar eclipse was always the arc of a circle. Third, here on Earth itself, ships disappeared beyond the horizon hull-first in whatever direction they were traveling.

All three observations could not be reasonably explained if the Earth’s surface were flat, but could be explained by assuming the Earth to be a sphere.

What’s more, Aristotle believed that all solid matter tended to move toward a common center, and if solid matter did this, it would end up as a sphere. A given volume of matter is, on the average, closer to a common center if it is a sphere than if it is any other shape whatever.

About a century after Aristotle, the Greek philosopher Eratosthenes noted that the Sun cast a shadow of different lengths at different latitudes (all the shadows would be the same length if the Earth’s surface were flat). From the difference in shadow length, he calculated the size of the earthly sphere and it turned out to be 25,000 miles in circumference.

The curvature of such a sphere is about 0.000126 per mile, a quantity very close to 0 per mile as you can see, and one not easily measured by the techniques at the disposal of the ancients. The tiny difference between 0 and 0.000126 accounts for the fact that it took so long to pass from the flat Earth to the spherical Earth.

Mind you, even a tiny difference, such at that between 0 and 0.000126, can be extremely important. That difference mounts up. The Earth cannot be mapped over large areas with any accuracy at all if the difference isn’t taken into account and if the Earth isn’t considered a sphere rather than a flat surface. Long ocean voyages can’t be undertaken with any reasonable way of locating one’s own position in the ocean unless the Earth is considered spherical rather than flat.

Furthermore, the flat Earth presupposes the possibility of an infinite Earth, or of the existence of an “end” to the surface. The spherical Earth, however, postulates an Earth that is both endless and yet finite, and it is the latter postulate that is consistent with all later findings.

So although the flat-Earth theory is only slightly wrong and is a credit to its inventors, all things considered, it is wrong enough to be discarded in favor of the spherical-Earth theory.

And yet is the Earth a sphere?

No, it is not a sphere; not in the strict mathematical sense. A sphere has certain mathematical properties—for instance, all diameters (that is, all straight lines that pass from one point on its surface, through the center, to another point on its surface) have the same length.

That, however, is not true of the Earth. Various diameters of the Earth differ in length.

What gave people the notion the Earth wasn’t a true sphere? To begin with, the Sun and the Moon have outlines that are perfect circles within the limits of measurement in the early days of the telescope. This is consistent with the supposition that the Sun and Moon are perfectly spherical in shape.

However, when Jupiter and Saturn were observed by the first telescopic observers, it became quickly apparent that the outlines of those planets were not circles, but distinct ellipses. That meant that Jupiter and Saturn were not true spheres.

Isaac Newton, toward the end of the seventeenth century, showed that a massive body would form a sphere under the pull of gravitational forces (exactly as Aristotle had argued), but only if it were not rotating. If it were rotating, a centrifugal effect would be set up which would lift the body’s substance against gravity, and the effect would be greater the closer to the equator you progressed. The effect would also be greater the more rapidly a spherical object rotated and Jupiter and Saturn rotated very rapidly indeed.

The Earth rotated much more slowly than Jupiter or Saturn so the effect should be smaller, but it should still be there. Actual measurements of the curvature of the Earth were carried out in the eighteenth century and Newton was proved correct.

The Earth has an equatorial bulge, in other words. It is flattened at the poles. It is an “oblate spheroid” rather than a sphere. This means that the various diameters of the earth differ in length. The longest diameters are any of those that stretch from one point on the equator to an opposite point on the equator. The “equatorial diameter” is 12,755 kilometers (7,927 miles). The shortest diameter is from the North Pole to the South Pole and this “polar diameter” is 12,711 kilometers (7,900 miles).

The difference between the longest and shortest diameters is 44 kilometers (27 miles), and that means that the “oblateness” of the Earth (its departure from true sphericity) is 44/12,755, or 0.0034. This amounts to 1/3 of 1 percent.

To put it another way, on a flat surface, curvature is 0 per mile everywhere. On Earth’s spherical surface, curvature is 0.000126 per mile everywhere (or 8 inches per mile). On Earth’s oblate spheroidical surface, the curvature varies from 7.973 inches to the mile to 8.027 inches to the mile.

The correction in going from spherical to oblate spheroidal is much smaller than going from flat to spherical. Therefore, although the notion of the Earth as sphere is wrong, strictly speaking, it is not as wrong as the notion of the Earth as flat.

Even the oblate-spheroidal notion of the Earth is wrong, strictly speaking. In 1958, when the satellite Vanguard 1 was put into orbit about the Earth, it was able to measure the local gravitational pull of the Earth—and therefore its shape—with unprecedented precision. It turned out that the equatorial bulge south of the equator was slightly bulgier than the bulge north of the equator, and that the South Pole sea level was slightly nearer the center of the Earth than the North Pole sea level was.

There seemed no other way of describing this than by saying the Earth was pearshaped and at once many people decided that the Earth was nothing like a sphere but was shaped like a Bartlett pear dangling in space. Actually, the pearlike deviation from oblate-spheroid perfect was a matter of yards rather than miles and the adjustment of curvature was in the millionths of an inch per mile.

In short, my English Lit friend, living in a mental world of absolute rights and wrongs, may be imagining that because all theories are wrong, the Earth may be thought spherical now, but cubical next century, and a hollow icosahedron the next, and a doughnut shape the one after.

What actually happens is that once scientists get hold of a good concept they gradually refine and extend if with a greater and greater subtlety as their instruments of measurement improve. Theories are not so much wrong as incomplete.

This can be pointed out in many other cases than just the shape of the Earth. Even when a new theory seems to represent a revolution, it usually arises out of small refinements. If something more than a small refinement were needed, then the old theory would never have endured.

Copernicus switched from an Earth-centered planetary system to a Sun-centered one. In doing so, he switched from something that was obvious to something that was apparently ridiculous. However, it was a matter of finding better ways of calculating the motion of the planets in the sky and, eventually, the geocentric theory was just left behind. It was precisely because the old theory gave results that were fairly good by the measurement standards of the time that kept it in being so long.

Again, it is because the geological formations of the Earth change so slowly and the living things upon it evolve so slowly that it seemed reasonable at first to suppose that there was no change and that Earth and life always existed as they do today. If that were so, it would make no difference whether Earth and life were billions of years old or thousands. Thousands were easier to grasp.

But when careful observation showed that Earth and life were changing at a rate that was very tiny but not zero, then it became clear that Earth and life had to be very old. Modern geology came into being, and so did the notion of biological evolution.

If the rate of change were more rapid, geology and evolution would have reached their modern state in ancient times. It is only because the difference between the rate of change in a static Universe and the rate of change in an evolutionary one is that between zero and very nearly zero that the creationists can continue propagating their folly.

Again, how about the two great theories of the twentieth century; relativity and quantum mechanics?

 

Newton’s theories of motion and gravitation were very close to right, and they would have been absolutely right if only the speed of light were infinite. However, the speed of light is finite, and that had to be taken into account in Einstein’s relativistic equations, which were an extension and refinement of Newton’s equations.

You might say that the difference between infinite and finite is itself infinite, so why didn’t Newton’s equations fall to the ground at once? Let’s put it another way, and ask how long it takes light to travel over a distance of a meter.

If light traveled at infinite speed, it would take light 0 seconds to travel a meter. At the speed at which light actually travels, however, it takes it 0.0000000033 seconds. It is that difference between 0 and 0.0000000033 that Einstein corrected for.

Conceptually, the correction was as important as the correction of Earth’s curvature from 0 to 8 inches per mile was. Speeding subatomic particles wouldn’t behave the way they do without the correction, nor would particle accelerators work the way they do, nor nuclear bombs explode, nor the stars shine. Nevertheless, it was a tiny correction and it is no wonder that Newton, in his time, could not allow for it, since he was limited in his observations to speeds and distances over which the correction was insignificant.

Again, where the prequantum view of physics fell short was that it didn’t allow for the “graininess” of the Universe. All forms of energy had been thought to be continuous and to be capable of division into indefinitely smaller and smaller quantities.

This turned out to be not so. Energy comes in quanta, the size of which is dependent upon something called Planck’s constant. If Planck’s constant were equal to 0 erg-seconds, then energy would be continuous, and there would be no grain to the Universe. Planck’s constant, however, is equal to 0.000000000000000000000000066 erg-seconds. That is indeed a tiny deviation from zero, so tiny that ordinary questions of energy in everyday life need not concern themselves with it. When, however, you deal with subatomic particles, the graininess is sufficiently large, in comparison, to make it impossible to deal with them without taking quantum considerations into account.

Since the refinements in theory grow smaller and smaller, even quite ancient theories must have been sufficiently right to allow advances to be made; advances that were not wiped out by subsequent refinements.

The Greeks introduced the notion of latitude and longitude, for instance, and made reasonable maps of the Mediterranean basin even without taking sphericity into account, and we still use latitude and longitude today.

The Sumerians were probably the first to establish the principle that planetary movements in the sky exhibit regularity and can be predicted, and they proceeded to work out ways of doing so even though they assumed the Earth to be the center of the Universe. Their measurements have been enormously refined but the principle remains.

Newton’s theory of gravitation, while incomplete over vast distances and enormous speeds, is perfectly suitable for the Solar System. Halley’s Comet appears punctually as Newton’s theory of gravitation and laws of motion predict. All of rocketry is based on Newton, and Voyager II reached Uranus within a second of the predicted time. None of these things were outlawed by relativity.

In the nineteenth century, before quantum theory was dreamed of, the laws of thermodynamics were established, including the conservation of energy as first law, and the inevitable increase of entropy as the second law. Certain other conservation laws such as those of momentum, angular momentum, and electric charge were also established. So were Maxwell’s laws of electromagnetism. All remained firmly entrenched even after quantum theory came in.

Naturally, the theories we now have might be considered wrong in the simplistic sense of my English Lit correspondent, but in a much truer and subtler sense, they need only be considered incomplete.

For instance, quantum theory has produced something called “quantum weirdness” which brings into serious question the very nature of reality and which produces philosophical conundrums that physicists simply can’t seem to agree upon. It may be that we have reached a point where the human brain can no longer grasp matters, or it may be that quantum theory is incomplete and that once it is properly extended, all the “weirdness” will disappear.

Again, quantum theory and relativity seem to be independent of each other, so that while quantum theory makes it seem possible that three of the four known interactions can be combined into one mathematical system, gravitation—the realm of relativity—as yet seems intransigent.

If quantum theory and relativity can be combined, a true “unified field theory” may become possible.

If all this is done, however, it would be a still finer refinement that would affect the edges of the known—the nature of the big bang and the creation of the Universe, the properties at the center of black holes, some subtle points about the evolution of galaxies and supernovas, and so on.

Virtually all that we know today, however, would remain untouched and when I say I am glad that I live in a century when the Universe is essentially understood, I think I am justified.

Summary

Civil engineers and climate change scientists are on a collision course.  The outcome could have very serious, nationally important consequences.  These differences should be resolved as a matter of urgency.

In this submission it is demonstrated with a very high degree of assurance that southern Africa, and possibly the rest of the world as well, is about to enter a period of severe droughts commencing within the next twelve months.  There is an estimated 20% likelihood that they will be as serious as the Great Depression Drought of the early 1930s.  These drought sequences could have disastrous consequences for South Africa if the authorities are caught unawares.

This prediction is based on the well researched multi-year periodic behaviour of the hydro-meteorological processes.  It is shown that this periodicity is in turn causally related to synchronous variations in solar activity.  This linkage is well documented, and has been studied in South Africa for more than a hundred years.

However, climate change scientists vigorously deny both the predictable, multi-year periodicity in the hydro-meteorological processes, as well as the solar linkage.  The study of the solar linkage with the hydro-meteorological processes does not feature in the Water Research Commission’s recently released publication on future research for the period 2008 to 2013.  This period coincides with the predicted occurrence of severe drought sequences.  The drought sequences will be causally related to the ‘quiet sun’. This is raising concern among international solar physicists.

This is an urgent, national policy issue.

Introduction

Just before the outbreak of World War II Albert Einstein fled from Germany to the USA. He warned President Roosevelt that the Germans were developing nuclear weapons.  The Americans assembled a group of scientists, who examined this possibility. They eventually developed their own nuclear weapons.  Two of these were used in Japan, and brought World War II to an end.

I now find myself in a similar position.  Based on my exhaustive studies, starting in 1970 through to the present day, it is my duty to report that there is a very real possibility (about 20%) that South Africa and other parts of the world could experience drought sequences of severity equal to the Great Depression drought experienced in the early 1930s.  This was a global drought.  It was called the Dustbowl Drought in the USA.

This led to joblessness in both South Africa and the USA.  Governments launched large construction projects to relieve unemployment.  These included the construction of the Vaal-Harts and other large water supply projects in South Africa, and the Boulder Dam and other projects in the USA.

I personally recall seeing ‘white labourers’ pushing cocopans for upgrading the roads, while on my way to school.  My parents had to support three of my cousins, whose parents lost their jobs.

In later years, from 1970 to 1984, I was directly responsible for developing national scale policies for flood routing through South Africa’s major rivers, and more importantly, drought operation procedures for our major dams.  I developed drought operation procedures for the Vaal and Mgeni River systems for use by their water boards.

I can assure SAICE Council that a repetition of the droughts of the 1980s could potentially cause considerable damage to South Africa’s economy on a scale equivalent to the consequences of present electricity shortages.  A repetition of the Great Depression droughts would be disastrous, particularly if, as is quite likely, they occur concurrently with the restrictions on electricity usage, and the global economic recession that has already started to occur. These droughts will increase the incidence of poverty, malnutrition and disease in South Africa, and more so in the countries to the north of us.

Drought predictability

In 1970 the multi-disciplinary, national Commission of Enquiry into Water Matters produced a comprehensive report.  Its recommendations led to the establishment of the Water Research Commission and the post of Manager: Scientific Services in the Department of Water Affairs.  I later occupied this post.

Regarding drought analyses, the commission recommended that research be undertaken on the development of a river flow prediction model, however approximate it may be, and that the possible connection with solar activity be researched.

This possible linkage with sunspot activity was not new. It was well known that in the 1850s British astronomers reported that a linkage existed between sunspot activity and famines in India. Here in South Africa, in 1892 DE Hutchins published an extensive report Cycles of drought and good seasons in South Africa. He demonstrated that there was a predictable linkage between sunspot activity and temperature, rainfall and river flow. During the first 50 years of the past century there was sporadic mention of the linkage in the reports of national drought commissions.

I was appointed as Chief of the Division of Hydrology in 1970.  Together with my staff, we addressed the predictability issue and the linkage with sunspot activity.  I published a comprehensive technical report in 1978. I reported that although a linkage existed, it was too weak for predictive purposes.  In retrospect, the reason for the lack of success was the shortness of the hydrological records at that time.  As we were later to demonstrate, it was not the single (about 11-year) sunspot cycles that were important, but the double (about 21-year) sunspot cycles.

Also in 1978 I held a  course on water resource and flood analyses at the department’s Hydrological Research Institute.  This proved to be very popular, and I received requests for repeats from the Department of Agriculture and from Professor Rooseboom at the University of Pretoria. Together with colleagues I continued presenting these courses every two years from then on. As and when time permitted, I continued my research on the predictable linkage.

I retired from the Department of Water Affairs and Forestry at the end of 1984 after a long and very satisfying career.  I then accepted (with alacrity), the offer of a post as professor in the Department of Civil Engineering (now Department of Civil and Biosystems Engineering) at the University of Pretoria.  In addition to my undergraduate teaching, I continued my research.  Together with colleagues, I also continued with our popular Hydro courses.  These have been attended by some 2000 participants to date, many of them repeats.

Climate change 

My first experience with the climate change issue commenced in 1993 when, at the request of the Department of Water Affairs and Forestry, we hosted a small discussion group on this subject.  Some of the participants expressed concerns that climate change would have an adverse effect on South Africa’s water supplies.

By then I had already undertaken further studies of the hydrological data for my own research as well as for our courses. Hydro courses.  I informed the meeting that there was no evidence in the data that could be attributed to climate change.

This was obviously a very important issue, so I decided to follow the publication route in peer reviewed journals, where I specifically addressed the predictability issue and the solar linkage.  By then it was obvious from my studies that there was a predictable, multi-year periodicity in the data and that this was closely, but not exactly, synchronous with the double sunspot cycle. A flip-flop mechanism was also present. There were sudden climatic reversals from low to high runoff conditions and back again.

It is very important that readers of this submission should note that at all times in my studies, I used periodicity in the data as the prediction tool and NOT the sunspot cyclicity. In our joint SAICE paper last year my colleagues and I demonstrated that there is a causal relationship between the predictable multi-year periodicity in the data, and the acceleration and deceleration of the sun as it moves along its trajectory through galactic space. 

The diagram below is our river flow prediction model prepared by my co-author Alwyn vd Merwe. We are presently in period year 13 (2007-08).

Note the very clear, well above average recorded river flows for the present hydrological year (13). Even more importantly, note the succession of below average river flows in the period years that lie ahead (14 to 20). Analyses of other long hydrological data series show similar characteristics.    

Once again, our prediction model based on this thoroughly studied, synchronous linkage between periodic solar activity and the hydrometeorological processes has been tested and verified. The likelihood of prolonged, severe droughts from next year onwards is very real. My research over the years and the successful predictions based on it, were reported in the following published papers and reports.

It has become increasingly clear that the South African hydrometeorological database is one of the best in the world. This, together with our geographical location within the band of maximum rate of poleward redistribution of incoming solar energy, makes southern Africa the ideal region for testing the validity of climate alarmist theories.

My predicament

All the above is a straightforward lead-up to my prediction of an imminent severe national, and probably global, drought.

There is, however, another very important but unpleasant issue that I’m obliged to bring to the SAICE Council’s attention.  Since 1993, I have become increasingly aware of the considerable body of scientific opinion that maintains that continued global increases of undesirable greenhouse gas emissions, principally carbon dioxide, from coal burning power stations, heavy industries (including cement manufacture) and transport, will create a greenhouse effect in the atmosphere.  This will result in increasing global temperatures. 

Climate change scientists used complex global climate computer models to predict a whole range of undesirable consequences.  These include increases in the magnitude and frequency of damaging floods, droughts and threats to water supplies.  They go further, and specifically maintain that there is no linkage between variations in solar activity and climatic responses.  They are forced to do this, as an admission would diminish their claims of exclusive human causality of the postulated consequences of global warming.

I emphasise the word ‘postulated’, because the claims are based on unverified (and unverifiable)  computer models.  This is the essence of my problem.  There is simply no evidence in the hydrological data to support these claims. For example, during the 20 years since the establishment of the IPCC in 1988, there have been no floods or droughts that have exceeded the historical maxima. Nor are there any observable trends in the rainfall and river flow data. 

My own position and responsibilities are very clear.  Since 1993 I have devoted considerable time and effort in a search for evidence that would support these claims.  Had I found this evidence, I would not have hesitated for one moment to report it and include it in my teaching, publications, articles and our Hydro course notes.

I therefore have an equal if unpleasant responsibility. It is to report that there is no observable substance to claims related to the effects of climate change on river flow and South Africa’s water resources.

International situation

The IPCC reports claim that the world will face very serious environmental and humanitarian consequences if global greenhouse gas emissions are not reduced, let alone stabilised. There is virtually unanimous international support for these conclusions at the political level. It is the implementation of measures to control these emissions that has become a major economic and political issue.  

I attended the United Nations conference on climate change in Bali last December at the invitation of a New Zealand organisation.  The purpose of the conference was to develop an enforceable agreement whereby all the nations of the world would pass legislation to reduce their greenhouse gas emissions.  However, the major developing nations, China and India, with their rapidly rising industrial activities and consequent increases in greenhouse gas emissions, were not prepared to implement these restrictions on the basis that the high expenditures would retard their poverty alleviation measures. The conference failed to meet its objectives.

It was then decided to continue the attempts to reach an international agreement by a series of meetings culminating in a final meeting in Copenhagen at the end of 2009.

The first of these meetings was held two weeks ago in Bangkok.  A third element entered into the picture. The poor nations, particularly the African nations and the island states, were also under pressure to implement these restrictive measures.  At Bangkok, they insisted that the developed nations that had caused the global warming with all its consequences, should compensate them for all the damage that, according to the IPCC documentation has already been caused, and will continue to be caused in the future.  These are huge sums of money. It is most unlikely that in addition to imposing economic burdens on their own populations, the major developed countries will be willing to impose further taxes on their citizens for donations of this magnitude to African countries. An impasse has been reached.

The Bangkok discussions not only failed to meet their objectives, but the international political situation has deteriorated still further.  The United Nations Commissioner conceded last week that a future substantial international agreement on the reduction of greenhouse gas emissions (the successor to the Kyoto Protocol) was unlikely to be achieved in future. This is particularly so in the light of the current economic recession.  Here in South Africa we are already suffering from the delay in the expansion of our coal-fired power generation network. As a consequence, global greenhouse gas emissions will continue to rise inexorably.

To make matters worse, the rising oil prices have resulted in an international rush for coal. Instead of decreasing, South Africa’s exports of coal have risen dramatically as has our domestic usage. The same applies to many other countries. Environmentalists are up in arms.

Climate change science

Until about 2001 there was virtual unanimity among climate change scientists that greenhouse gas emissions have caused and will in future continue to cause severe environmental and humanitarian damage.

This has changed.  Scientists in the affected sciences, particularly those in the applied and engineering sciences, have started to raise serious doubts regarding the very basis of climate change science.  Our research on the solar linkage is an example.  Russian and other solar physicists have noted the unusual delay in the commencement of the next sunspot cycle.  They are warning that there is a possibility that the world could be entering another cold period similar to the historical ice ages that lasted for decades.

Other scientists are questioning the postulated linkage between rising carbon dioxide emissions and global temperatures.

In my article on the likelihood of a global drought submitted to the SAICE magazine and my more extensive course notes that I presented at the University of Pretoria earlier this year, I demonstrated that a linkage also exists between variations in solar activity and global temperatures. My analyses replicate the slowing down in the rate of increase of global temperatures followed by the present decreasing tendency. This is despite the increases in global greenhouse gas emissions.

Summary so far

  1. There is overwhelming evidence of a causal and predictable linkage between variations in solar activity and climatic responses, specifically rainfall and river flow.
  2. There is no evidence of trends in rainfall and river flow data that could be attributed to unnatural climate change.
  3. There is increasing worldwide research that questions the fundamental basis of climate change theory.
  4. The international political situation regarding the implementation of universal measures to restrict greenhouse gas emissions has collapsed.
  5. Recommendations that South Africa should resort to the development of measures to adapt to human caused climate change will fail because they would be adapting to something that does not exist.

Water Research Commission

I now have another unpleasant task.  Please accept my assurance that this is not a personal issue.

Yesterday I was shown a copy of a report published by the Water Research Commission titled Towards defining the Water Research Commission’s research portfolio on climate change for 2008-2013.  I was amazed, frightened and disappointed in that order.

The very first requirement when planning future research is to carry out a literature study of existing knowledge.  This was obviously not done. The huge volume of decades of research by civil engineers on floods, droughts and water resources were completely ignored. In my 93-page extended summary of my technical report An assessment of the likely consequences of global warming on the climate of South Africa, I list 50 references on this subject. A literature study would have demonstrated that virtually all the principal research fields in the WRC document have already been researched.

In the report no attempt at all is made to evaluate the basic assumption that human activities have had and will continue to have adverse effects on South Africa’s water supplies.

The well-documented causal linkage between solar activity and river flow is ignored.

My own conscientious and detailed research published in peer-reviewed literature, copious notes, and presented at courses for practitioners from 1978 onwards, some of which are listed above, was completely ignored.

My peer-reviewed paper in the Water Research Commission’s Water SA and magazine articles Water Wheel were obviously ignored.

I have no wish to comment on the report in detail, but would gladly do so, if requested.

Department of Water Affairs and Forestry

This brings me back in a full circle.  I served with honour and pleasure in the department for 34 years.  I fully appreciate that things have changed since I retired from the department.  However, there are basics that do not change.  The very foundation of all the department’s actions and responsibilities rest on an understanding of the properties of river flow.  This is all the way from initial planning through to design, construction and operation of water resource development projects.

My major concern, and reason for this submission to the SAICE Council, is that the department does not seem to fully realise the consequences that severe water resource droughts will have on their future drought operations, bearing in mind our recent research and publications.  This is compounded by the department’s apparent acknowledgement that climate change will have an adverse effect on South Africa’s water resources, for which there is no believable evidence.

Recommendations

I’ve done my best and achieved great satisfaction for the work that I have done for my profession and my country.  I cannot shoulder these responsibilities any longer.  It is now up to SAICE to decide on what action should be taken from here onwards.  I suggest that this submission, plus any comments that the council wishes to add, be submitted by the SAICE Council as a matter of urgency to Director General of the Department of Water Affairs and Forestry, and to the Chairperson of the Water Research Commission, together with the accompanying second draft of my article that is in press.

I recommend that a joint workshop be organised by SAICE, the Department of Water Affairs and the Water Research Commission. It should be held in July this year as a matter of urgency. Its limited objective should be to discuss the likelihood of severe water resource droughts occurring in the near future, and the action that should be taken to minimise the consequences. Notice of the workshop and invitations to attend and participate in it should be distributed as soon as possible and included in the June issue of the SAICE magazine.

My further urgent recommendation is that the Water Research Commission should take note of the unequivocal, predictable periodicity in the hydrological data and its causal linkage with synchronous variations in solar activity. The commission should consider what this undeniable periodicity has on all the commission’s future research activities, specifically those linked with climate change as set out in its recent publication on research proposals, where this fundamental causal linkage is completely ignored.

Finally, I urge the Department of Water Affairs and the Water Research Commission to seriously consider the consequences if this warning and its linkage with solar activity are ignored and the droughts occur.

I appreciate that the contents of this document are likely to be hotly contested as lucrative research funding is at stake. This debate should be encouraged, provided it is conducted in an appropriate forum where both sides are given the opportunity to present their views. In this connection I must place on record that my several attempts to have round table discussions on this subject were either refused or ignored. 

This submission is not confidential. On the contrary, it is my wish that it be widely distributed. I intend distributing it immediately after my discussions with the SAICE Council.

First and foremost, for me, knowledge is a journey, and I’m happy to hang around with people I can learn from. I prefer to do this in a pleasant way, hence the preference for comfortable chats over a cup of tea. My mother was a veritable teapot, and my late academic advisor, Professor Tony Bray, conducted all our research fuelled by tea and scones. It involves respect, courtesy, charming etiquette, and admission of our own ignorance.

Tony once described what I do as “agricultural astrophysics”. I try not to be disparaging about particle physics because a) I don’t understand it, and b) it sometimes does something useful (or so I’m told). In the field of experimental particle physics, I probably come closest to a glimmer of understanding when I’m thinking about neutrinos. An extra, distinct energy transport mechanism (besides light) was needed to explain conservation of energy and momentum in chemical reactions, so neutrinos were predicted, along with a means of detection (they are optically invisible). When a neutrino impacts an atomic nucleus (preferably a single proton), it emits a flash of mauve Cherenkov light (which is optically visible) aligned with the source. When large bodies of interactive material with prominent protons (like heavy water) are put somewhere shielded from ambient radiative pollution, we do in fact see patterns of Cherenkov light apparently aligned with sources of radio activity. 

 In order to make sense of this, statistical adjustments are made to get a fit with the model of the day. For example, although the neutrino flux density on Earth according to theory must be on the order of several billion neutrinos per square millimetre per second, neutrino observatories like Sudbury typically see less than one Cherenkov flash per hour. From that they extrapolate a beautiful, complex sub-model like flavour-changing. All this is accomplished without yet dealing with antineutrinos. When matter particles meet antimatter particles, they tell us, there is an energetic explosion and both are annihilated. Well don’t hold your breath! Not a single explosion has been observed, although, they tell us, the neutrino-antineutrino blizzard is thicker than Scotch broth by a factor of about 1050. 

 Nor does something need to be seen to qualify as “observed”. The tau neutrino is listed as the latest addiction of “directly observed” particles in the Standard Model of Particle Physics, and likewise, the MSW effect (oscillation between types of neutrinos) is credited in the literature with having been “directly observed”. With respect, in both cases what was actually observed was the mathematical formalism.

 I don’t think it’s hard to see why I plough the fields of science with a tractor I can sit on. These guys just don’t make sense to me. I’m glad they don’t build bridges!

The principles I am following (and which seem to appeal to your sensibilities) are that 1). Physics is a branch of science that deals with quantities that are measurable. 2.) All measurements in physics can be made in four basic dimensions - mass, length, time, and polarity (charge). With these we understand distance and time, and therefore speed and acceleration. Thus we understand the effects of force, and consequently projectile motion, ballistics, friction, optics, and action-at-a-distance (like orbital motion and magnetic fields). Motion can be expressed differently depending on the co-ordinate frame preferred, and that is what we call relativity. Tie physics in with chemistry, and we have a coherent, empirical explanation of our physical neighbourhood. No hocus-pocus. In my view, any theory concocted outside of these (physical) principles is just a mind-game, and falls into the category of “green elephant theories” (after the guy who famously offered US$100,000 to the first person who could disprove his theory that the Universe propagates by green elephants laying speckled eggs in Black Holes. Of course, his money was safe). 

I miss Tony so much, he was the rudder on my ship, and I’ve had a hard time of it regaining forward momentum since he left. I hasten to add that he was a professor of electronics engineering, specialising in high-energy circuits. As a consultant for GEC, he travelled the world, designing and installing huge projects that spanned continents. They worked and as far as I know, are working still. He was not interested at all in Green Elephant theories.

Common sense tells us that when we weigh an elephant, we must take into account the creature that rides upon its back and subtract it to get the correct weight for the elephant; quantitative observation tells us that the creature is in fact a flea and that we needn’t bother because the difference is insignificant. Studies involving fine measurement indicate that anthropogenic carbon emissions are a flea on the climate’s back, and spending billions on trying to cut that little flea in half will do nothing but make the poor poorer. The fact of the matter is, we cannot significantly control the climate, for better or for worse. Global warming, when it happens, is a completely natural, inevitable, solar-driven cycle. If it were not for global warming, without any input from mankind, then we would not have emerged from the last ice age. The major problem facing our terrestrial environment is human over-population. If we could cut the population density, then the waste products of human enterprise, including carbon and DDT and methane from sheep, would be cut along with it. That’s the core of the problem, the actual cause of our headache, and taking an aspirin doesn’t cure it. Anthropogenic Global Warming is a myth feeding off our collectively guilty political conscience.

Firstly, on the question of bias, we all have bias. As soon as one has an opinion, one has bias. It’s as natural as having an ego, which after all is just the apparent identity of our consciousness. Both ego and bias are necessarily part of a healthy psyche, unless and until they dominate our personalities. Then we become a right old pain to deal with! Our job as scientists is characterised by a battle to see the results of experiment and observation without the taint of bias, or with as little of it as possible. In a perfect world (which I believe is what we strive for, although it is unattainable), we would let the facts fall where they will, and follow the clues wherever they might lead. I think the first step in this direction is to do the primary analysis of any data set without reference to any particular model. We should look at solar data without first marshalling them into the corral of the Standard Solar Model, and we should look at cosmological data quite regardless of Big Bang Theory. That way we significantly reduce the effect of user bias on the object of observation.

The stars are what they are irrespective of the opinions expressed in the field of cosmology. It amazes me that pronouncements are made about distant objects with such unshakeable certainty when in the cold light of day the reach of verifiable science is not nearly so self-assured. I am reminded of Al Gore’s brazen assertion that “the science is settled” in climatology, a field which rivals cosmology in chaotic outcomes. The most daunting challenge facing space science is that of scale. In an infinite Universe, we will always be infinitely more ignorant than we are wise. In my view, we have more than enough to keep us occupied in the celestial neighbourhood, and would do well to take things one step at a time. Compare the science proposed in Hannes Alfven and Gustav Arrhenius “The Evolution of the Solar System” with Alan Guth’s pronouncements on Inflation Theory, or George Smoot’s take on the CMB, or indeed, even the core principles of General Relativity and Quantum Mechanics. The question I like to ask myself is “How does this theory connect to observed reality?” In a sitting room conversation with Halton Arp a few years ago, the late Fred Hoyle said, “I suppose that in the end, Chip, the Universe will have its say.”

The shocking reality is that research is done for money, not in pursuit of truth. The Theory of Everything which will no doubt be pronounced by high-energy physicists in the not-too-distant future will, I fear, be a set of mathematical sentences so arcane that none could render them false, and they would in any event be based upon experiments that have no intrinsic meaning discernable to scientists in more general research. In short, the magic will be witnessed and explained exclusively by the conjurors themselves, and we will have to decide on blind faith alone whether we believe them or not. What really happens in the Large Hadron Collider remains for the vast majority of us nothing more than conjecture, and I suppose their conclusions are inevitably going to form the basis of a large chunk (or even all) of cosmology.

Astronomers will play no part in where astronomy is going.

In the ancient epochs of astronomy, it was tightly bound to social superstition, and there was little to set it apart from the religion of the day. The celestial sphere was perceived to be nearby, and charmingly benign. It was as if the stars in the sky were merely a backdrop to a world that existed entirely to nurture and benefit people. The self-importance that resulted from this myopic view is staggering. I’m trying to stay away from religion as much as I possibly can in telling this story, but gosh it’s a circus! We have in this day and age a popular conception of the creator of the Universe who is proudly male!  Good grief! If there’s any one thing that persuades me that a literal take on biblical philosophy is incredibly naïve, it’s that God looks like a human male, and even more astoundingly, behaves like one, stereotypically. I’m not given to mocking the faith of others, but the conception of a patriarchal, sexist, chauvinist God is surely the most flabbergasting facet of a monumentally incredible belief system.

Science and religion eventually split, thankfully, and astronomy divorced itself at long last from astrology and fortune-telling for the rich and lazy. The development of the telescope in the 17th century gave the art a huge leg-up, and with it came revelation—the scale of the Universe was undoubtedly vast on the terrestrial scale, and there were other systems out there that emulated our own. Galileo saw planets in detail, and saw how they too had moons in orbit. He saw the phases of Venus, thereby verifying Copernicus’ model. Isaac Newton invented the reflecting telescope, published his cathartic, watershed Principia Mathematica, followed it with his Opticks in 1704, and we took off into a brave new world.

Discoveries in optics and the formulation of the concept of electromagnetism brought with them the stark realisation that much—perhaps most—of the cosmos is not perceptible to the human eye, and that the gentle, cocooning sky worshipped by our forefathers masked a Universe characterised by the most awesome violence. The revelation of invisible, high-energy radiation like X-rays and gamma rays, and later, the invention of instruments with which to detect them and transpose the images to optical wavebands, brought and still brings the most astounding discoveries about the large-scale environment. We began to get a glimmer of understanding of the overwhelmingly inhospitable world in which we have fortuitously found ourselves the tiniest speck of eco-friendliness. We are indeed in that sliver of “just-rightness” that we charmingly call the Goldilocks Zone.

The Milky Way is a barred spiral galaxy of average size, about 100,000 light years in diameter, and containing somewhere between 100 billion and 400 billion stars (we are stymied by the fact that we can’t look at it from outside). Some daring astronomers have estimated that it has about 50 billion planets, of which about 500 million are in the habitable zone, like the Earth is. Wow!

It would be easy to make too much of this. Especially in the Greco-Roman world of the last two millennia, patriarchal, monotheistic religion dominated and ruled with a heavy hand. The importance of our own species in the scheme of things was fertile ground for the propagation of a cosmology that was gloriously homo-centric. Quite honestly, I don’t have too much of a problem with that. We are at the centre of our own universe. This is the place that we look from. Apart from that though, the Earth’s address is not special. What is fairly obvious to the trained eye is that whatever we are part of, it is the outcome of these violent processes. Out of the strong came forth sweetness; from the fires of hell came the Earth, in all her sublime glory.      

The search for extra-terrestrial intelligence, and things like the Drake equation that are used to encourage that pursuit, are based on a fundamental assumption that is not only puzzling but indeed also tacitly misleading. The notion is that life is the product of a chemical reaction—given the right ambient chemistry, something lifeless can become a living thing. What on Earth is that based upon? Life as we observe it is a relay race. The ephemeral spirit of living things is passed on through procreation, from one living thing to another, and although the terms and conditions of such a process are carried in a specifically coded molecule called DNA, life itself is quite another phenomenon. Living things always eventually become dead, but nowhere do we have an instance where something properly dead has been made alive again. We can recreate the chemical conditions pretty much exactly, but sorry, no cigar. We might want life to be a purely chemical process, but such a wishful supposition has not a single empirical precedent. Nowhere. I don’t care whether you’re an atheist, the Pope’s cousin, or a bionic meter maid, there is nothing in all the vast body of scientific observation and experiment that you could use to prop up the idea.

I have on my bookshelf a publication by Hoyle and Wickramasingh called “Lifecloud”, in which they put forward their hypothesis of panspermia. Simply put, their idea was that life could have been brought to Earth from other stars by comets. On one hand, it’s an appealing notion because it avoids the dubious premise that biological life could be created from sterile ingredients in a test tube or some particular “primordial stew”. Indeed, panspermia sidesteps the issue of a creation point for life altogether. In an infinite Universe, life could have existed always, and may of course migrate from place to place in living organisms. That brings us to the Achilles heel of panspermia: How would these living things stay alive during the rigours of the journey, from temperatures of minus 270 degrees C in interstellar space to a fiery descent in a planet’s atmosphere? Can’t see it myself. It answers some questions but raises others. Pity…

The proposal that life evolved from some prior lifeless state, given, say, organic compounds, water, and just the right temperature and pressure is utterly without basis in science. That we could spend millions of dollars building models over so fragile a foundation is typical of the way science is going, I’m afraid.

Cosmology: Myth or Science?

 

For the Golden Jubilee of the Indian Academy of Sciences, representing a culture which has investigated cosmology for four millennia

1. Pre-Galilean cosmologies

 

1.1 Ancient Cosmological Myths

Cosmology began when man began to ask: What is beyond the horizon and what happened before the earliest event I can remember? The method of finding out was to ask those who had travelled very far; they reported what they had seen, and also what people they had met far away had told them about still more remote regions. Similarly, grandfather told about his young days and what his grandfather had told him and so on. But the information was always increasingly uncertain the more remote the regions and the times.

 

The increasing demand for knowledge about very remote regions and very early times was met by people who claimed they could give accurate information about the most distant regions and the earliest times. When asked how they could know all this they often answered that they had direct contact with the gods, and got revelations about the structure of the whole universe and how it was created. And some of these prophets were believed by large groups of people. Myths about the creation and structure of the universe were incorporated as essential parts of religious traditions.

 

In different cultures, the mythologies became drastically different, depending on the way the philosophical thinking developed and on the personalities of great prophets. In several of the world religions, both the universe and the gods were believed to the eternal; in others, the gods or one God created the universe. In some religions, there is no conflict between these views; initially the universe was identical with a god and the different members of his body developed into the different parts of the universe. In India during the Vedic period, the god Purusa was initially identical in the whole world, and part of his body became the Earth, other parts the Heaven; the Sun formed from his eyes and the Moon from his soul. In other philosophical-mythological schools, both Heaven and Earth are regarded as gods and as parents of gods. Sometimes one god—in India, Agni or Soma or Rudra—and sometimes all gods together are said to have generated or created the whole universe.

 

In Rigveda, there is a remarkable poem telling that originally “There was neither Aught nor Naught, no air nor sky beyond”. There was only “A self-supporting mass beneath, and energy above. Who knows, who ever told, from whence this vast creation rose? No gods had yet been born – who then can e’er the truth disclose?”

 

During the more than three millennia which have passed since the Vedic period, Indian mythology has developed a jungle of co-existing creeds, in part absorbed from neighbours, and in part from earlier cultures which had collapsed. The sophisticated mythological philosophy is, perhaps, somewhat less chaotic. There is a general tendency to consider the evolution of the universe as well as the human society to be periodic. Indeed, there is a hierarchy of periods. ? golden age, followed by a silver, a bronze and the present iron age (Kaliyuga) forms a Mahayuga of 54,000 years. A number of Mahayugas forms a larger period, and so on in steps up to the Kalpa or the day of Brahma, which is 4 × 109 years. This is only half an order of magnitude smaller than what according to the Big-Bang hypothesis should be the ‘age of the universe’.

 

However, there are 365 Brahma days in one Brahma year, and Brahma lives for 100 years, so the ancient Indians used time units which were four orders of magnitude longer than in the Big Bang. (Of course, when Brahma dies after his 100 years, he is immediately reborn). Indian estimates of the size of the world were not so fantastic.

 

Sometimes the figure10,000 yojanas is given, which means less than half the distance to the Moon. The Mediterranean-Middle East thinking was initially as closely related to the Indian mythologies as Greek, Latin, and Persian are related to Sanskrit. The way of life of the people speaking these languages was also similar. The battle of Kuruksetra and the battle before the walls of Ilion took place at about the same epoch and were fought in a similar way. The heroes spent day after day fighting, and at dusk they went back to their camps, drinking and bragging. Their gods took a decisive part in the fight. (By the way, in Scandinavian mythology, the Vikings who fell in battle came immediately to Valhalla, where they enjoyed the same type of daily life). In the same way, the Mediterranean mythology was initially similar with a golden, silver, bronze and iron age in sequence. However, the Greek cosmological philosophy which took the lead at the Greek cultural explosion around 500 B.C. did not develop like the Indian. First of all, the world remained very limited in time. Indeed, the guesses of the age of the world considered periods of some thousand years, which is only one micro-kalpa. On the other hand, the estimates of the size of the universe were not so different.

 

Not all the early cosmologies were so intimately connected with religion. The sages of China had no preconceived theories, and seem to have based their cosmological thinking more on phenomena which they observed. But the observations they could make did not suffice for any certain conclusions, and any more elaborate scenarios were no less speculative than those which originated from divine revelation to prophets.

 

1.2 Buddhist Cosmology

 

Buddhism developed views on cosmology which were drastically different from the other Indian cosmologies. As Buddhism is basically an agnostic religion, it does not deny the possible existence of gods, but it does not claim that there are any. The existence of gods is irrelevant to the aim of Buddhism, which is to find the right way to salvation, to the annihilation of desire, to the state of Nirvana.

 

As a logical consequence of this, when the Buddha was asked whether the universe was eternal or created he is reported to have answered in his characteristic style:

 

It is wrong to say that it is eternal.

It is wrong to say that it is created.

It is wrong to say that it is both eternal and created.

It is wrong to say that it is neither eternal nor created.

 

Perhaps this is an echo from the quoted Rigveda poem which probably derives from one millennium earlier: As man got his knowledge about the early states of the universe from prophets who got their knowledge directly from the gods, then no information could be gained about the epoch when the gods had not yet been born. Similarly, as the Buddha did not believe in gods—or in any case, did not care much about them—there was no possibility to get information about early cosmology.

 

Perhaps one could also find an echo two millennia later, when Descartes proclaimed: De omnibus est dubitandum (We should question everything). However, this is not altogether correct because Descartes had also inherited the Galilean scientific tradition according to which controversial issues should be settled by reference to experiment and observation. But there does not seem to be any basic logical conflict between Descartes and the agnosticism of Rigveda and the Buddha.

 

1.3 Rise of Mathematics

 

1.3.1 The Pythagoreans

 

A new element in the cosmological discussion was introduced by the rise of science and natural philosophy in Greece as a part of the cultural explosion around 500 B.C. The Greeks had absorbed astronomical knowledge both from the Mesopotamian and Egyptian cultures, and, as we have mentioned already, their mythology was genetically related to the Indian. The new element consisted of the rise of geometry, which to a large extent derived from Egypt, where it was of practical importance for land surveying. The Greeks developed this to the still unsurpassed masterpiece of logically stringent structure which we know as Euclidean geometry. It is questionable whether the beauty of the theorem of the regular polyhedrons will ever be surpassed. By a simple discussion which anyone can understand in a few minutes, the a priori surprising conclusion is reached that there are five and only five such bodies.

 

Strongly connected with this, a much wider breakthrough of new thinking was achieved by the Pythagoreans. They demonstrated that the basis of musical harmony was simple ratios of integers. It is quite understandable that this led to a philosophical optimism. The Pythagoreans tried to incorporate astronomy and cosmology as well into their philosophy. They claimed that astronomy should be to the eye what musical harmony was to the ear.

 

This was indeed a revolutionary idea. It was the first attempt to construct a comprehensive mathematical scheme of cosmology and to work out a synoptic view of the universe as a whole. One may say that its basic principle is that because the world was created by the gods, there must be a sublime order in its basic structure – even if many regrettable local disorders were obvious. According to the Pythagoreans, the most ‘perfect’ geometrical figure is the circle, and the most ‘perfect’ of all solid bodies is the sphere. Ergo the Earth must be a circular disk or a sphere, surrounded by a number of crystal spheres, on which the planets and the stars were located. Further, the most perfect motion was uniform motion. Ergo the crystal spheres must rotate with uniform velocity. This was necessary for the ‘harmony of the spheres.’

 

1.4 Relation between Theory and Observation

 

Neither the Pythagoreans nor Plato cared very much for a comparison with observations. The Pythagoreans formed a secret society with no real contact with the rest of Greek society. Indeed, traitors were severely punished. The rules of Plato’s Academy included: “Let none who has not learnt geometry enter here,” and he advised all scholars to “concentrate on the theoretical side of their subject and not spend endless trouble over physical measurements to the neglect of theoretical problems.”

 

This was in conformity with the general attitude of the intellectual aristocracy in Greece. The belief was that technology, including technological innovation, ought to be largely relegated to the lower classes, especially to slaves. It was degrading for a philosopher to get his hands dirty.

 

It has been suggested that this cleft between sophisticated theoretical thinking and practical work, including experiments, was the basic reason why the highly advanced science in ancient Greece never led to the scientific breakthrough which took place in Europe two millennia later.

 

1.4.1 The Ptolemaic System

 

When, in spite of Plato, observations began to attract interest, the Pythagorean cosmology seemed to be confirmed by observations in one respect: the outermost crystal sphere, the one on which the stars were fixed, did apparently move with a constant speed. This was just what could be expected because this sphere was the outermost one, closest to where the gods lived, and hence most divine. Unfortunately, the theory did not agree so well with observational results when applied to the planets, including the Sun and Moon. The Sun and the Moon sometimes moved more to the north, sometimes to the south, and a planet like Jupiter sometimes reversed its motion in relation to the stars.

 

It was obvious that something was wrong. But the basic principles—uniform motion and perfect geometrical figures—were sacrosanct and could not be given up even if they were in conflict with observations. Instead, very ingenious auxiliary ideas were forwarded. Planets are not directly fixed on the crystal spheres, but each is fixed on a small circle, an epicycle, which moved with a constant velocity with its centre fixed on the crystal sphere. For a time such theories looked promising, but better observations demonstrated that they were not accurate. The reaction of the scientists was to try to patch up an old fiction instead of asking themselves whether, after all, its basis was laid in truth. They tinkered instead of recreating. Hence, increasingly complicated additions to the system were made.

 

The result of this was the Ptolemaic system, which was worked out in the third century A.D. No less than 54 epicycles, eccentrics, etc., had been introduced. But at the same time, as it became more complicated, it became more sacrosanct. When an avalanche of religious fanaticism put the classical culture into a deep freeze for more than a millennium, it did not develop very much, and age made it still more sacrosanct. Criticism was dangerous, and it was a rare exception when the famous astronomer, King Alphonse X of Castile, complained about its degree of complexity: “Had I been present at the creation, I could have rendered profound advice.”

 

1.4.2 Astronomy, Astrology, and Myth

 

This mathematically based cosmology did not come into serious conflict with the ancient myths. They became to a certain extent incorporated, and a jungle grew up of mathematics, astronomy, astrology, and myths from many earlier cultures. Gods and spirits of all kinds began to settle on the crystal spheres, soon causing a population explosion. For example, one group of constellations depicts how Perseus saved Andromeda from Medusa, whose terrible head is represented by a variable star. Still more dramatic is the giant hunter Orion, who, followed by the Big Dog and the Small Dog, lifts his club against the red-eyed Bull.

 

The early motion of the Sun along the ecliptic was illustrated by a number of sun-myths. For example, when Heracles fought a bull and later a lion, this is thought to represent the Sun’s entry—on its walk along the zodiac—into the constellations Taurus and Leo. Another sun myth, in which Delilah cuts Samson’s hair from which his strength derives, tells us that in the fall, when the Sun enters the constellation Virgo, its rays lose their heating power and he becomes a captive for half a year, until spring, when he has regained his force.

 

This chaotic conglomeration of mathematics, astronomy (including cosmology), and myths from many religions has turned out to be a permanent ingredient in our culture. Today, after more than 2000 years, it has as much vitality as ever. Newspapers and periodicals usually have astrological columns; every jeweller sells pendants and pins with signs of the zodiac. From the point of view of our commercialized society, there are many more dollars in astrology than in astronomy.

 

1.5 Creation Ex Nihilo Versus Ungenerated Universe

 

The rise of the monotheistic religions meant that one of the gods became more important than the others; He became the Pharaoh, the dictator of the Heavens, God with capital ‘G’. He also became more important than the material world. He alone was eternal. He was not a product of the evolution of the universe, as in Rigveda. On the contrary, the whole world was a secondary structure created by Him. In the Bible the creation takes six days. It still has the character of bringing order into a pre-existing chaos. It was not until the first few centuries A.D. that creation was thought of as the production of the world ex nihilo (but this is never taught in the Bible). God had now become powerful enough to create the whole world by just pronouncing some magic words, or by his will-power.

 

Monotheistic religions have often a tendency to become fanatic. Certainly Christendom did so, at least during some periods. Tertullian said Credo quia absurdum (I believe because it is absurd). Hence there should be no serious attempt to reconcile religion and science. In the Aristotelian philosophy the material world was ‘ungenerated and indestructible’, a view which is not in conflict with some of the Rigvedic views. It was not until medieval times that Aristotle’s views were accommodated to the idea of creation ex nihilo essentially by Saint Thomas, who remodelled the Aristotelian philosophy in accordance with the requirements of ecclesiastical doctrine.

 

It is of interest to remember that even Saint Thomas confessed that reason could only be satisfied with the assumption that the world had no.beginning. “The doctrine of a beginning or the non-eternity of the world is to be received sola fide, as an act of pure faith in deference to authority.”

 

Not even the monotheistic religions were fatal to the old myths. The ‘pagan’ gods changed their names—some became devils, others became saints. In Italy, one pays homage to saints in the same places in the woods where earlier a nymph or a dryad used to live. They have only acquired more modern dress. Midwinter solstice was in ‘pagan’ times the festival of the Sun-god, and a fertility Moon-goddess was worshipped at the first full moon after the vernal equinox. These nice old traditions remain, even today, although with a modified meaning.

 

The ancient belief that the wandering stars governed the life of men was conserved and developed further. Astrology, mythology and religion formed an increasingly complicated, fascinating structure. The basic conflict between an omnipotent God and the old belief that our destiny is governed by the stars was patched over by the formula: Astra regunt hominem, sed regit astra Deus (Stars rule men, but God rules the stars) The scientific basis of the Ptolemaic system, viz., that the stars move according to certain mathematical laws, was forgotten.

 

1.6 Myth Versus Science; Mathematical Myths

 

The Ptolemaic system was initially a quite attractive theory but, during the centuries, it developed into a sacred and rigid structure increasingly impotent in incorporating new discoveries. The reason for this was that fundamentally the approach was not scientific but mythological.* The basic ideas were the perfect geometrical figures and uniform motion. The idea of building a world system on such general principles represented great progress, because earlier it had been generally believed that events in the world were governed by the will or the whimsies of gods. The Ptolemaic system did not necessarily question that the celestial system was created by the gods, but it claimed that they must have acted according to certain philosophical or mathematical principles which it was possible to analyze and understand. A sufficiently sophisticated mathematician might find out what the divine mathematic principles were.

 

The Ptolemaic system originated from what we may call a mathematical myth. The Pythagorean philosophy had a logical beauty which could well be called ‘divine.’ By pure abstract thinking the theoreticians claimed to have discovered the principles according to which the gods acted when they created the world. And when these principles were found, it was held that the world must be structured according to them. In a way, the demiurges had no choice; it was not even necessary that they existed. But not even observations of physical reality were necessary. The system was based on divine inspiration or logical-mathematical necessity. If Galileo claimed that in his telescope he saw celestial bodies or sunspots which a priori do not exist, it was his telescope and not the theoretical system which was wrong.

 

It is a semantic question whether a model initially deriving from ‘divine inspiration’ should be called a mytheven if it includes philosophical and mathematical elements. Some would no doubt prefer to call it, for example, ‘a priori metaphysics’.

 

But long before Galileo, new ideas had appeared in Islamic culture, which took the lead in science less than 100 years after the Hegira. In the twelfth century, Avaroës from Cordova claimed that the world is eternal—not created, but in a state of evolution (Singer 1959), a view which is similar to the hierarchical cosmology of today. In his impressive treatise Mugadema Ibn Khaldun (around 1400 AD) dared to oppose Plato’s view that the world could be explored by logical thinking alone. Indeed, he said that “logic is not a safe way of thinking, because of its tendency towards abstraction and its remoteness from the tangible world” (Baali & Ward 1981). This is similar to Bertrand Russell’s warning half a millenium later against ‘unaided reason’. Ibn Khaldun claimed explicitly that cosmology must be based on observations.

 

1.7 The Copernican System

 

The Ibn Khaldun idea had to hibernate for two hundred years until it reappeared in Europe, where it led to the well-known crisis which resulted in the victory of the Copernican heliocentric system (but after some time the latter had to abdicate in favour of a ‘galactocentric’ system).

 

1.8 The Tycho-Brahe Compromise

 

During the fight between the geocentric and the heliocentric cosmologies, an ingenious compromise was proposed by Tycho Brahe. His cosmology accepted that all the planets moved around the Sun, but the Sun (together with all the planets) moved around the Earth. (The Moon also moved around the Earth.) In this way he satisfied the observations which indicated that the planets moved around the Sun, but he conserved the sacrosanct geocentric cosmology. The Tycho-Brahe cosmology agreed with observations about as well as the Copernican cosmology. But it soon turned out that the basic issue was another. It was the survival or defeat of a sacrosanct myth. The myth had been sterile. It had not been able to predict a single new phenomenon which later was confirmed by observation.

Hi John,

My position is that universal expansion is an extraordinary hypothesis (we do not observe expansion), and that therefore the burden of proof lies with those who propose it. Both redshift (Hubble Law) and CMBR are specious. We have a situation that is analogous with the proposal of Copernicus - from Earth, we observe that the Sun passes around the Earth, which appears to be at rest and central. Copernicus made an extraordinary proposal, that the Earth in fact rotates about its polar axis and creates the illusion that the Sun passes overhead. The burden of proof rested with him, and those who supported him. They succeeded, and now we have a proper understanding of the dynamics of the Solar System. No such verification of the expansion theory has been forthcoming and we therefore must continue to believe what we see (a static Universe) until we are shown otherwise.

To answer your question more directly: The best lines of evidence for a static Universe are those that falsify the expanding Universe - namely, exposing the myth of the Hubble Law (proper motion of quasars is a powerful argument against cosmological redshift) and showing that the fit of the CMBR to the model is extremely loose and heavily contrived. In this respect, I have not developed my arguments much since my book. I have been absorbed by what I regard as increasing certainty that there is design, and therefore a Designer, behind everything we can see in the cosmos. I see order emerge from chaos, time and again, and to my mind, that requires design. The Universe, as I see it, is not decaying to higher entropy. On the contrary…

Kind regards

Subject: Re: question

Hello Hilton,

Thanks for your explanation.

I have a slightly different topic. I know from our conversations that you are convinced that Physics as it is currently practiced is misleading itself spectacularly. 

Specifically you point out that there has been a shift over the last century and a half from an ‘observe first, develop mathematical model second’  style of Physics and Cosmological enquiry to today’s approach of ‘develop mathematical model first, observe second’.

Subtle but crucial.

I’m reading in New Scientist an article entitled “Dark matter no-show at sensitive underground lab”. Its interesting because the article illustrates your concern perfectly. Here we are looking for something because our mathematical model hypnotizes us into ‘knowing’ WIMPs must exist.

But one comment took my eye, “Dark matter is needed to explain where the gravity comes from that stops spinning galaxies from flying apart.” Hilton what does stop the galaxies from flying apart? Don’t we need dark matter or something like it?

Thanks,

Cliff

Good question. We need to take into account the difference between dark matter and Dark Matter, between unseen baryonic matter and unseen non-baryonic matter. My friend and compatriot Gerrit Verschuur (author of the highly recommended popular science book “Interstellar Matters”) went a long way to explaining what dark matter is and how to quantify it. It’s a fairly old term in astronomy and refers to stuff for which the radiant image is too weak by the time it gets to us for whatever reason, and for which we don’t have instruments powerful enough to acquire and resolve the picture. An examples is molecular hydrogen which exists in vast interstellar clouds but which until fairly recently could not be seen. Verschuur (a professional observational astronomer and professor of astrophysics) realised this from the early 20th century work of pioneer astro-photographer E. E. Barnard. There are dark patches in the Milky Way (eg, the Coal Sack near the Southern Cross) which were long thought to be holes or voids because we could see nothing there. Advancing technology brought us redemption from that ignorance however, and we now know from observation that the “voids” in fact contain lots of normal baryonic matter. We just couldn’t see it for a long time. That’s dark matter. Normal, everyday atoms and molecules. I urge you to read Verschuur’s book. It’s a fine example of space science without hocus-pocus.

What stops anything we can see from flying apart? Gravitation. In the Solar System, which is close enough for us to see most of the stuff affecting gravitation, Newtonian Mechanics quantifies it pretty much exactly, and we can make stunningly accurate predictions based upon those laws (eg, the flight path of interplanetary space craft). When we move further afield however, things are not so clear (the Spatial Credibility Factor - uncertainty is proportional to remoteness). The nearest spiral galaxy in our study is M31 (Andromeda), about 3 million LY away. At that distance we have only fuzzy detail and much of what is there cannot be seen. Based on what we can see, the rotation curves of spiral galaxies seem to be anomalous. The way that they rotate does not align with the observed distribution of mass within the galaxy disk, and this is true whether we use the formulae of Newton or Einstein. Something’s missing from the equation.

Here is where East and West part company, and the twain look set upon doing astronomy independently. Both Newtonian camp and Einsteinian camp do agree on one thing however, and that is that we are missing some mass in there somewhere. However, the solutions proposed are radically different. In the classical, mechanical view, if we know enough about the initial conditions, we can safely predict the outcome. Therefore, if the outcome that is observed doesn’t fit, we’ve missed something up front. The common analogy is a roulette wheel - if we know the initial conditions, eg the weight and and size and velocity of the ball, the rotational speed of the wheel, the starting point, etc etc, then we could with confidence predict which number it will land up in. If we try to calculate the result but leave a significant mechanical influence out of the equation (eg, ignoring the Sun’s shifting barycentre when calculating the orbit of Mercury) we get to some degree a wrong or inaccurate answer. The system we are using is not defective; we have just not used it properly.

The Big Bang Model, and its forebear, General Relativity, require some tuneable factors in the equation to work properly in the mathematical sense, and included in these are both Dark Mtter and Dark Energy (which actually work against each other by attracting and repulsing respectively). The theory is so weak in fact, that these dark things would comprise over 96% of the model, and the stuff we observe, experiment with, and analyse in detail less than 4%. The model urgently needs observational support, and desperation sires rose-tinted spectacles. So the rotational anomaly in galaxies filled the need. By adding arbitrary, adjustable quantities of Dark Matter (a supernatural substance), and by awarding Dark Matter just the properties in needs for the job, they get galaxies to work in terms of their model, and consequently imply that their model has received observational support. It’s tragically funny.

This is in my considered opinion extremely weak science. The Newtonian solution is crucially different in concept and execution. Electrophysicists Chuck Gallo and James Feng have shown that by simply reorganising the distribution of normal mass in the galaxy disk, there is no problem. It works. It’s dark matter, not Dark Matter. There is no need to change the laws of physics (see attachments).    

The crucial point to remember is that we have seen the development of mathematics from a set of formulae to return quantities, to become an arcane language that returns concepts. Those in the latter school will argue with some merit that their conceptual interpretations are often aligned with later observation; I reply that the former always aligns with observation since it is derived from observation. Where it appears not to, it is in my view simply a case of weak eyesight.

Thank you for asking the questions you do.

Kind regards

It appears that some clever sod has written a piece of malware which is targeting my blog. It is apparently trawling through email ID lists and registering random new users to my blog, at the rate of about 100 per day. I have no idea how to stop it.

If you have been included in this nuisance, please accept my sincere apologies. If it doesn’t die a natural death the soon, this piece of sardonic Internet programming will force me to shut my blog down and start a new one. I’m kinda wishing that the law of karma really does work, and the author of this little piece gets banished to a colony of virulent mosquitoes for the rest of his days.

If anyone has any idea how I can stop it, please let me know!
