| The text below contains my findings which may be of interest to people who have inquisitive minds and want to discover how Nature really works. (This text is taken from my book "Foundational Flaws in Modern Physics", which can be found at [Only registered users see links. ]) FOREWORD Writing about modern science - Roger G. Newton remarked that Its most important characteristic is to rely neither on authority nor on individual revelation or intuition. That is not to say that scientists and mathematicians never take the word of an authoritative and highly regarded colleague on faith. They often do; no one can go through the details of every mathematical proof or repeat every experiment. ..."Nobody knows more than a tiny fraction of science well enough to judge its validity and value at first hand," argues Michael Polanyi. "For the rest he has to rely on views accepted at second hand on the authority of a community of people accredited as scientists." (Newton: [R#1] p.120) Obviously, one can't check every mathematical proof and repeat every experiment; and one should not have to. This would be a terrible waste of time and resources. However, there are facts which force us to re-examine experimental evidence and the conclusions which are based on it. As a well-known physicist - Stephen Hawking - concluded: "the general theory of relativity and quantum mechanics ... are known to be inconsistent with each other - they cannot both be correct" (Hawking: [R#2] p.11-2). However, we know that both theories are claimed to be experimentally proved to be correct. Obviously, this is an indication that some of our so-called 'proofs' are misleading and that it is necessary to re-examine them. When re-examining experiments - it is not that difficult to discover that in some important cases people who designed and conducted these experiments have not done a good job in drawing conclusions from the data they collected. It seems that due to this, even the leaders in physics are sometimes unaware of what experimental evidence really tells us. Moreover, as Brian Martin (a Professor of Social Sciences at the University of Wollongong) pointed out: In spite of popular views to the contrary, scientific research is an incredibly conservative enterprise: innovation of particular sorts is welcomed, but challenges to fundamental principles are typically rejected out of hand. The reason is simple: many prestigious and not-so-prestigious scientists have an enormous stake in the prevailing set of ideas and directions. (Martin: [R#3]) One would think that Brian Martin exaggerates and that in the field of physics - if such "challenges to fundamental principles" were well supported by evidence, they would not be rejected. What may surprise you, dear reader - this is not always the case. We should not forget the fact that these leaders are only human; as Mendel Sachs remarked, one must take account of the fact that, far from being totally objective thinking machines, scientists are only human - along with all of the 'hang-ups' that go with this label! - such as irrational prejudices in science to fight off, as well as other emotional restraints, such as the near-omniscience that the scientist sometimes attributes to the leaders in his field! (Sachs: [R#4] p.108) And this is detrimental for progress in physics. When a prominent physicist writes that some tenet is proved by experimental evidence, it doesn't seem to come to other physicists' minds that just the opposite may be true. Hence, in practice, many assumptions in physics are based only on the authority of people with impressive credentials. And, what is very unfortunate, these assumptions are presented then as undeniable facts - even though they are disproved by modern experimental evidence. For example, the assumption that a body following a geodesic is in inertial motion - as the geometric explanation of gravitation implies - has been contradicted by the Gravity Probe 'A' experiment (which has been conducted in 1976). As has been explained in section 2.2.1 ([Only registered users see links. ]), the results showed that the freely falling clock, which was used in this experiment, was perfectly well "aware" of changes of its speed (even though it did not "feel" any force). The clock was also well "aware" of the magnitude of the gravitational potential. And this proves that the commonly accepted assumption, that the gravitational field is cancelled in free fall, is incorrect. This also proves that the equivalence principle is not strictly correct (see §2.3 [Only registered users see links. ] to §2.5 [Only registered users see links. ] in other words, there is no complete equivalence between the effects of gravitation and the effects of accelerated motion. So we cannot consider the equivalence principle as a law of nature; as we do now. But no physics textbook even mentions these facts. Is it that physicists are unaware of them? It is possible because the article ([R#5]), in which the results of the above mentioned experiment have been published, has been written in a really enigmatic way. E.g., although the clock employed in this experiment was in free fall like in Einstein's elevator - the authors did not mention this and didn't even use the expression "free fall". It is very puzzling that the authors did not explicitly write about the most significant findings of this experiment, which I mentioned above. So one can see why other physicists could have overlooked them and don't discuss them. On the other hand, many of the physics texts discuss experimental evidence which is in agreement the Equivalence Principle (EP). Thus, the impression has been created that this principle is correct and that the gravitational fields are of relative existence. But this is a false clue which leads astray new investigators who work on trying to unify physics. For example, there are many experts who work on quantizing the energy of gravitational fields. However, evidence seems to indicate that this work doesn't make sense. Energy - like mass - gravitates. However, as has been explained in section 5.1 ([Only registered users see links. ]), there are experiments which tell us that there is no gravitation of the energy of gravitational fields; which means that this energy does not exist. It is hard to believe, but EP is used to disvalue this experimental evidence. This is done by repeating the argument which has been brought up in "Gravitation" by Misner et al., according to which the gravitational energy "is not localizable. The equivalence principle forbids" (Misner et al.: [R#6] p.467). If EP is not valid, there is no basis to claim that this energy exists; and this means that quantizing the energy of gravitational fields is a futile exercise. Moreover, because EP has been the only basis for the claim that acceleration is relative - this claim is incorrect too. But this means that, contrary to what physics text books state, acceleration is absolute. And, hence, the general relativity principle is incorrect. In 1959 V. Fock wrote in one of his books that "the purely relative nature of acceleration is invalidated" (Fock: [R#7] p.208). And he presented valid arguments for this claim and also for his claim that the equivalence principle is not valid. But his arguments have been ignored and many physicists with impressive credentials claim that acceleration is relative, as if they were unaware of the fact that the 1976 experiment proved Fock's conclusions right. In any case, what young physicists are taught now is - in this case - in contradiction with experimental evidence. Another example: We know that the speed of light measurements always render the same result. Let's say we have a measuring rod and points A and B mark its ends. We send a light signal from point A to point B, where the signal is reflected by a mirror back to A. If we measure the time it took this signal to travel from A to B and back to A, we get the speed of light by dividing the total distance (2 * AB) by this time. However, we know that the lower in a gravitational potential a clock is - the lower its rate is. So how can a local measurement of the speed of light in a gravitational field give the same result as such measurement outside of this field? If the clock is slower it must take light more time to cover the same distance in a gravitational field; otherwise the result would imply that the local speed of light is greater. The assumption that there is some spacetime curvature cannot change anything because we check the straightness of the rod by comparing it to the path of light, so if this path is curved then the rod must be curved too; and the length of the path of light AB would not be affected by this. The results of the experiments conducted by Irwin Shapiro (in 1966-7) and later by others - are also in agreement with the conclusion that the speed of light in a gravitational field is decreased (depending on the magnitude of gravitational potential). The time delay (of the returns of radar signals) observed there, cannot be explained by the increase of the path of the signal due to the bending of this path, because this contribution is a few orders of magnitude too small (see §4.5 [Only registered users see links. ]). What makes the issue especially puzzling is the fact that in his book, "Relativity - The Special and General Theory", Einstein wrote that: according to the general theory of relativity, the law of the constancy of the velocity of light in vacuo, which constitutes one of the two fundamental assumptions in the special theory of relativity ... cannot claim any unlimited validity. A curvature of rays of light can only take place when the velocity of propagation of light varies with position. (Einstein: [R#8] p.76) But despite all this - leading physicists deny the fact that "the velocity of propagation of light varies with position". In his book - "Faster than the Speed of Light" - Joćo Magueijo writes: Very few things in science are as rock solid as Einstein's theory of relativity. Yet my idea challenges nothing less - to extremes that could be perceived as a physicist's career suicide. Unsurprisingly, a well-known popular science tabloid used the title "Heresy" for an article about this work. (Magueijo: [R#9] p.1) And a few pages further, he explains what this "heresy" was. He writes: And ever since [1905], the constancy of the speed of light has been woven into the very fabric of physics, into the way physics equations are written, even into the notation used. Nowadays, to "vary" the speed of light is not even a swear word: It is simply not present in the vocabulary of physics. (Magueijo: [R#9] p.6) So despite experimental evidence - leading physicists imply that the speed of light does not vary, because special relativity does not allow for this. And Einstein's statement - that "the law of the constancy of the velocity of light in vacuo ... cannot claim any unlimited validity" - is also ignored; as is his explanation that: "A curvature of rays of light can only take place when the velocity of propagation of light varies with position". It seems that, today, Einstein himself would probably be considered as a heretic. The question must arise: Why is it that leading physicist don't want to accept the fact that the coordinate speed of light varies? There seems to be only one explanation. We know only one reason for the speed of light to be changed: a change of the index of refraction of space through which the light travels. Ironically, attributing physical properties to empty space is also considered as a "heresy", because such space is like the old ether. In 1920, in his Leiden lectures, Einstein pointed out that: "Certainly, from the standpoint of the special theory of relativity, the ether hypothesis appears at first to be an empty hypothesis" (Einstein: [R#10] p.15). However, as he added further on: But on the other hand there is a weighty argument to be adduced in favour of the ether hypothesis. To deny the ether is ultimately to assume that empty space has no physical qualities whatever. The fundamental facts of mechanics do not harmonize with this view. (Einstein: [R#10] p.16) And on the next page he presented one of these facts, writing that: It is true that Mach tried to avoid having to accept as real something which is not observable by endeavouring to substitute in mechanics a mean acceleration with re- ference to the totality of the masses in the universe in place of an acceleration with reference to absolute space. But inertial resistance opposed to relative acceleration of distant masses presupposes action at a distance; and as the modern physicist does not believe that he may accept this action at a distance, he comes back once more, if he follows Mach, to the ether, which has to serve as medium for the effects of inertia. (Einstein: [R#10] p.17-8) There can be no doubt that inertial effects hint us that space has some physical properties; otherwise a body would not even "know" that it is accelerated and would not resist to its acceleration the more the faster it moves. So it is hard to understand why the ether was rejected. Moreover, the retardation of clocks due to motion is a causal effect; which means that the clocks must physically "feel" that they are moving. Obviously these clocks can feel only motion relative to something physical; and whether we call it ether, or space with physical properties, is of little importance. Besides, the fact that the speed of light does not depend on the speed of its source - must also be considered as evidence for the existence of the ether (or space with physical properties). Also, the fact that Maxwell deduced the speed of light from the knowledge of properties of space such as permittivity and permeability - indicates that these properties are real and of physical significance. But because abstract concepts don't have physical properties - these properties must also be considered as evidence for the existence of the ether or space with physical properties. Paradoxically - all this evidence is ignored, because it is claimed that Einstein disproved the ether and nobody seems to care that in 1920 Einstein wrote that, Recapitulating, we may say that according to the general theory of relativity space is endowed with physical qualities; in this sense, therefore, there exists an ether. Ac- cording to the general theory of relativity space without ether is unthinkable; for in such space there not only would be no propagation of light, but also no possibility of existence for standards of space and time (measuring-rods and clocks), nor therefore any space-time intervals in the physical sense. (Einstein: [R#10] p.23) So there are many roles which something, like the ether, has to play; and therefore, many reasons to believe that it does exist. Simply, without it - we have no way to explain how nature works. (See §§1.3.3 ([Only registered users see links. ]) - 1.3.6 for more details.) In spite of the above, leading relativity physicists are definitely unwilling to accept the fact that space has physical properties which depend on gravitational potential. Why? There are two main reasons: 1. If the index of refraction of empty space varies with gravitational potential, then the bending of light and the time delay of light don't prove that space is curved. As we know, light rays will also be bent when they travel through the atmosphere, if its density or temperature varies. Would it make sense to claim that this atmosphere is curved? The same way it does not seem to make sense to say that empty space is curved if it is the varying index of refraction that causes light rays to be bent. 2. If the index of refraction of empty space varies with gravitational potential, then the total energy of the electrostatic field of a charged elementary particle must also vary. And this must mean that the rest mass of this particle depends on the gravitational potential. However, this undermines the belief that spacetime geometry explains gravitation. This also proves that the equivalence principle is of limited validity and that it cannot be considered as a law of Nature. The problems mentioned in the last two sentences seem to be unacceptable for leading relativity physicists; so they claim that the rest masses do not vary depending on the gravitational potential. And this leads us to another controversial subject. Let me explain: Today many prominent physicists imply (in their books on physics) that a photon which climbs up in a gravitational field looses energy and frequency. We know that the natural frequencies of atoms are affected by gravitational field. The lower in a gravitational field an atom is, the lower its resonant frequencies. Let's imagine that an atom A emits light at one of its resonant frequencies towards another atom B which is of the same kind and is positioned "higher" in this gravitational field. The radiation is compared there to the resonant frequency of the atom B undergoing the same transition. We know what the difference will be; moreover, experiments leave no doubt that the magnitude of the observed difference is only the result of these atoms radiating at different frequencies and that the radiation from the atom A does not loose its frequency while travelling "up". So why do even known physicists falsely imply that it does? For example, a known relativist, Clifford M. Will, wrote: A question that is often asked is, Do the intrinsic rates of the emitter and receiver or of the clocks change, or is it the light signal that changes frequency during its flight? The answer is that it doesn't matter. Both descriptions are physically equivalent. Put differently, there is no operational way to distinguish between the two descriptions. ...to get a gravitational red shift, we must separate the clocks in height; therefore, we must connect them by a signal that traverses the distance between them. But this makes it impossible to determine unambiguously whether the shift is due to the clocks or to the signal. ... [p. 50] ... This is a key aspect of relativity, indeed of much of modern physics: we focus only on observable, operationally defined quantities, and avoid unanswerable questions. (Will: [R#11] p.49-50) Why does this prominent physicist write that it doesn't matter whether the photon changes its frequency or not? I was thinking about this for years, but only one answer comes to my mind. Unambiguous statement that this photon does not loose energy - forces one to acknowledge that a particle falling down in a gravitational field does not gain in total energy either; otherwise a perpetuum mobile could be constructed, as I've explained in section 5.4 ([Only registered users see links. ]) in my book. And this means that the rest mass-energy of a particle depends on the magnitude of the gravitational potential. But this is in contradiction to what is commonly assumed on the basis of modern (incorrect) interpretation of general relativity. So saying that we don't know whether the photon looses energy - saves our incorrect assumption and incorrect interpretation of general relativity from being seen as untenable. Moreover, if the value of the rest mass-energy of a particle varies - then it must depend on the properties of space in its position. So everything seems to be interconnected and one change in our assumptions leads to undermining other assumptions. Let's also notice that if a particle falling in a gravitational field doesn't gain energy from the field, then there is no need to postulate quanta of the energy of gravitational fields - gravitons; which are the hypothetical "carriers" of gravitational interactions. Noteworthy, the hypothesis of gravitons as carriers of gravitational interactions is untenable, because it leads to contradictions with the laws of conservation of energy and momentum. So the whole business of quantizing gravitational fields (or spacetime geometry) is a misguided effort and a waste of time and money. But will the experts who work in this field happily admit that they are on the wrong track? Will they be happy to give up on their current works, grants for them, etc.? As Professor Brian Martin pointed out: For any group that is able to acquire a disproportionate share of society's wealth, power, or status, it is advantageous for this inequality to be seen as legitimate. One of the key bases or supports for legitimacy in contemporary societies is scientific and technological expertise. Because scientific knowledge is widely believed to have an authority derived from nature, undisputed scientific knowledge claims can play a powerful legitimating role. ... When dissident experts challenge a scientific or technological orthodoxy, this potentially becomes a challenge to the privileges of groups associated with the orthodoxy, since the legitimacy of those privileges may be thrown into question along with the orthodoxy itself. (Martin: [R#12]) That's why, as Martin writes: "challenges to fundamental principles are typically rejected out of hand. The reason is simple: many prestigious and not-so-prestigious scientists have an enormous stake in the prevailing set of ideas and directions" (Martin: [R#3]). And in another place he writes that: "powerful scientists often develop a commitment to and a career investment in particular ideas, and react strongly against challengers" (Martin: [R#13]). I used to believe that experimental evidence decided whether a statement in physics was correct and acceptable or not. And when I came across some physics texts which seemed to indicate otherwise - I assumed that I must have misunderstood something. For years I used to assume that the problems existed only in my imagination. I could not believe that physics community would put up with so much dubious or incorrect information presented as a scientific truth by people with impressive credentials. In their book, in which they compare the scientific research to a detective story, Albert Einstein and Leopold Infeld wrote that: "It is a familiar fact to readers of detective fiction that a false clew muddles the story and postpones the solution" (Einstein & Infeld: [R#14] p.6). Obviously, false clues in physics also postpone the solution; as can easily be seen in the field of the unification of physics research. In his book "The Trouble with Physics", published in 2006, Lee Smolin (a known expert on quantum gravity) writes that "by 1981, physics had enjoyed two hundred years of explosive growth. Discovery after discovery deepened our understanding of nature... Then, in the early 1980s, things ground to a halt" (Smolin: [R#15] p.XI). In the "Introduction" to the book Lee Smolin writes: "The story I will tell could be read by some as a tragedy." This state of affairs is surprising because, as Smolin writes, "far more people now work on problems in fundamental physics than in the whole combined history of the subject". Moreover, "there may be more professors of physics in a large university department today than there were a hundred years ago in the whole of Europe, where almost all the advances were being made" (Smolin: [R#15] p.262). In spite of this, according to Lee Smolin, "We are horribly stuck..." (Smolin: [R#15] p.311). As we know, relativity and quantum mechanics provide the basic foundation of modern theoretical physics. Lee Smolin pointed out that even though "Each of these is a beautiful, powerful and profound theory. ...neither can, because of the existence of the other, be said to constitute the basis for a general theory of physics." This we must conclude even though, supposedly, experimental evidence 'proves' that both are correct. In a hard to solve case, detectives cannot ignore any evidence. But this is what we do in physics. Should we be surprised that we cannot solve the problems encountered on the road to the unification of physics? Even though my book contains original solutions to couple of specific issues, the main purpose of my writing it - was to help in freeing physics of the incorrect assumptions, explanations and concepts which are responsible for the unprecedented stagnation in this field.
