"Relativity and Its Roots" By Banesh Hoffmann p.92: "There are various remarks to be made about this second principle. For instance, if it is so obvious, how could it turn out to be part of a revolution - especially when the first principle is also a natural one? Moreover, if light consists of particles, as Einstein had suggested in his paper submitted just thirteen weeks before this one, the second principle seems absurd: A stone thrown from a speeding train can do far more damage than one thrown from a train at rest; the speed of the particle is not independent of the motion of the object emitting it. And if we take light to consist of particles and assume that these particles obey Newton's laws, they will conform to Newtonian relativity and thus automatically account for the null result of the Michelson-Morley experiment without recourse to contracting lengths, local time, or Lorentz transformations. Yet, as we have seen, Einstein resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether. If it was so obvious, though, why did he need to state it as a principle? Because, having taken from the idea of light waves in the ether the one aspect that he needed, he declared early in his paper, to quote his own words, that "the introduction of a 'luminiferous ether' will prove to be superfluous." http://www.amazon.com/Physical-Relat.../dp/0199275831 Physical Relativity: Space-time Structure from a Dynamical Perspective Harvey R. Brown "It is the ultimate irony that the paper which would spell the demise of the luminiferous ether had as one of its central postulates what Wolfgang Pauli aptly called the 'true essence of the old aether point of view'. (...) The most remarkable feature of Einstein's light postulate is the fact that it seems at first sight antithetical to his own revolutionary notion of the light quantum. In 1905 it was far from clear to Einstein what sort of thing the light quantum precisely is, but it must have seemed closer in nature to a bullet than a wave. The fact that nonetheless Einstein adopted the LP over an emission theory of light is testimony to the sureness of his physical intuition in the midst of blooming, buzzing confusion." In 1954 Einstein realized that the "ultimate irony" had turned into ultimate tragedy: http://www.perimeterinstitute.ca/pdf...09145525ca.pdf Albert Einstein 1954: "I consider it entirely possible that physics cannot be based upon the field concept, that is on continuous structures. Then nothing will remain of my whole castle in the air, including the theory of gravitation, but also nothing of the rest of contemporary physics." If there is doubt as to whether the statement: "physics cannot be based upon the field concept, that is on continuous structures" is equivalent to the statement: "physics cannot be based on the assumption that the speed of photons, unlike the speed of bullets, is independent of the speed of the light source" here are a few clues: http://arxiv.org/ftp/physics/papers/0101/0101109.pdf "The two first articles (January and March) establish clearly a discontinuous structure of matter and light. The standard look of Einstein's SR is, on the contrary, essentially based on the continuous conception of the field." http://www.pbs.org/wgbh/nova/einstein/genius/ "And then, in June, Einstein completes special relativity, which adds a twist to the story: Einstein's March paper treated light as particles, but special relativity sees light as a continuous field of waves. Alice's Red Queen can accept many impossible things before breakfast, but it takes a supremely confident mind to do so. Einstein, age 26, sees light as wave and particle, picking the attribute he needs to confront each problem in turn. Now that's tough." http://arxiv.org/PS_cache/astro-ph/p.../0305457v3.pdf New varying speed of light theories Joao Magueijo "In sharp contrast, the constancy of the speed of light has remain sacred, and the term "heresy" is occasionally used in relation to "varying speed of light theories". The reason is clear: the constancy of c, unlike the constancy of G or e, is the pillar of special relativity and thus of modern physics. Varying c theories are expected to cause much more structural damage to physics formalism than other varying constant theories." http://www.ekkehard-friebe.de/wallace.htm The Farce of Physics Bryan Wallace "Einstein's special relativity theory with his second postulate that the speed of light in space is constant is the linchpin that holds the whole range of modern physics theories together. Shatter this postulate, and modern physics becomes an elaborate farce! (...) The speed of light is c+v." [Bryan Wallace wrote "The Farce of Physics" on his deathbed hence some imperfections in the text!] Pentcho Valev |

John Norton: "These efforts were long misled by an exaggeration of the importance of one experiment, the Michelson-Morley experiment, even though Einstein later had trouble recalling if he even knew of the experiment prior to his 1905 paper. This one experiment, in isolation, has little force. Its null result happened to be fully compatible with Newton's own emission theory of light. Located in the context of late 19th century electrodynamics when ether-based, wave theories of light predominated, however, it presented a serious problem that exercised the greatest theoretician of the day." http://philsci-archive.pitt.edu/1743/2/Norton.pdf John Norton: "In addition to his work as editor of the Einstein papers in finding source material, Stachel assembled the many small clues that reveal Einstein's serious consideration of an emission theory of light; and he gave us the crucial insight that Einstein regarded the Michelson-Morley experiment as evidence for the principle of relativity, whereas later writers almost universally use it as support for the light postulate of special relativity. Even today, this point needs emphasis. The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE." There are two facts hinted at in the above texts which, in a world different from Einsteiniana's schizophrenic world, would make the respective theory (special relativity) extremely suspicious: 1. Originally (in 1887) the Michelson-Morley experiment was compatible with the assumption that the speed of light varies with the speed of the light source (as predicted by Newton's emission theory of light) and INCOMPATIBLE WITH THE ASSUMPTION THAT THE SPEED OF LIGHT IS INDEPENDENT OF THE SPEED OF THE LIGHT SOURCE (Einstein's 1905 light postulate). 2. After a century of brainwashing no one wants to hear about the original truth - people just know that the Michelson-Morley experiment has gloriously confirmed Einstein's light postulate and that's it. Note how artfully Norton, while being faithful to the true story, still does not give any sign that something might be amiss. Pentcho Valev |

Albert Einstein 1912 (in letters to Ehrenfest): "I was not annoyed in the least by your article. On the contrary. Such considerations are quite familiar to me from the pre-relativistic time. I certainly knew that the principle of the constancy of the velocity of light is something quite independent of the relativity postulate; and I considered what would be more probable, the principle of the constancy of c, as was demanded by Maxwell's equations, or the constancy of c, exclusively for an observer sitting at the light source. (...) I believe that there are quite simple experiments to test Ritz' conception, which, incidentally, was also mine before rel. theory." The problem is that Maxwell's equations demanded that the speed of light be VARIABLE - it varied with the speed of the observer: http://culturesciencesphysique.ens-l..._CSP_relat.xml Gabrielle Bonnet, École Normale Supérieure de Lyon: "Les équations de Maxwell font en particulier intervenir une constante, c, qui est la vitesse de la lumière dans le vide. Par un changement de référentiel classique, si c est la vitesse de la lumière dans le vide dans un premier référentiel, et si on se place désormais dans un nouveau référentiel en translation par rapport au premier à la vitesse constante v, la lumière devrait désormais aller à la vitesse c-v si elle se déplace dans la direction et le sens de v, et à la vitesse c+v si elle se déplace dans le sens contraire." http://www.amazon.com/Brief-History-.../dp/0553380168 Stephen Hawking: "Maxwell's theory predicted that radio or light waves should travel at a certain fixed speed. But Newton's theory had got rid of the idea of absolute rest, so if light was supposed to travel at a fixed speed, one would have to say what that fixed speed was to be measured relative to. It was therefore suggested that there was a substance called the "ether" that was present everywhere, even in "empty" space. Light waves should travel through the ether as sound waves travel through air, and their speed should therefore be relative to the ether. Different observers, moving relative to the ether, would see light coming toward them at different speeds, but light's speed relative to the ether would remain fixed." http://www.pitt.edu/~jdnorton/papers/Chasing.pdf John Norton: "Finally, in an apparent eagerness to provide a seamless account, an author may end up misstating the physics. Kaku (2004, p. 45) relates how Einstein found that his aversion to frozen light was vindicated when he later learned Maxwell's theory: Kaku: "When Einstein finally learned Maxwell's equations, he could answer the question that was continually on his mind. As he suspected, he found that there were no solutions of Maxwell's equations in which light was frozen in time. But then he discovered more. To his surprise, he found that in Maxwell's theory, light beams always traveled at the same velocity, no matter how fast you moved." This is supposedly what Einstein learned as a student at the Zurich Polytechnic, where he completed his studies in 1900, well before the formulation of the special theory of relativity. Yet the results described are precisely what is not to be found in the ether based Maxwell theory Einstein would then have learned. That theory allows light to slow and be frozen in the frame of reference of a sufficiently rapidly moving observer." Pentcho Valev |

"In sum, Einstein rejected the emission hypothesis prior to 1905 not because of any direct empirical evidence against it, but because it seemed to involve too many theoretical and mathematical complications. By contrast, Ritz was impressed by the lack of empirical evidence against the emission hypothesis, and he was not deterred by the mathematical difficulties it involved. It seemed to Ritz far more reasonable to assume, in the interest of the "economy" of scientific concepts, that the speed of light depends on the speed of its source, like any other projectile, rather than to assume or believe, with Einstein, that its speed is independent of the motion of its source even though it is not a wave in a medium; that nothing can go faster than light; that the length and mass of any body varies with its velocity; that there exist no rigid bodies; that duration and simultaneity are relative concepts; that the basic parallelogram law for the addition of velocities is not exactly valid; and so forth. Ritz commented that "it is a curious thing, worthy of remark, that only a few years ago one would have thought it sufficient to refute a theory to show that it entails even one or another of these consequences...." (...) Einstein's theory garnered prestigious supporters such as Planck, Sommerfeld, and Wien, who endorsed and protected it from the attacks of others, while Ritz's theory acquired no supporters. Ehrenfest and Tolman called for unambiguous empirical evidence to test Ritz's emission theory, but neither spent any effort in extending it, and soon they both epoused Einstein's theory unreservedly, especially following de Sitter's work. For a few years immediately following its publication, Ritz's theory may have seemed to be an odd and complicated curiosity, in comparison to the leading approaches in electrodynamics. Ritz, the one man who had both the skill and the motivation to advance it, had died." Nowadays it is psychologically impossible to test, experimentally, the statements "the speed of light depends on the speed of the light source" (c'=c+v) and "the speed of light does not depend on the speed of the light source" (Einstein's 1905 light postulate, c'=c). The reason is that in Einsteiniana's schizophrenic world experiments are double-edged - if they confirm c'=c+v, they at the same time GLORIOUSLY confirm c'=c: http://groups.google.com/group/sci.p...abc7dbb30db6c2 John Norton: "THE MICHELSON-MORLEY EXPERIMENT IS FULLY COMPATIBLE WITH AN EMISSION THEORY OF LIGHT THAT CONTRADICTS THE LIGHT POSTULATE." Tom Roberts: "Sure. The fact that this one experiment is compatible with other theories does not refute relativity in any way. The full experimental record refutes most if not all emission theories, but not relativity." Pentcho Valev: "THE POUND-REBKA EXPERIMENT IS FULLY COMPATIBLE WITH AN EMISSION THEORY OF LIGHT THAT CONTRADICTS THE LIGHT POSTULATE." Tom Roberts: "Sure. But this experiment, too, does not refute relativity. The full experimental record refutes most if not all emission theories, but not relativity." Still people not affected by the schizophrenia could choose between c'=c+v and c'=c. If, as the observer starts moving towards the light source and wavecrests start hitting him more frequently, the frequency and the speed of light (relative to the observer) increase while the wavelength remains constant, then c'=c+v predicted by Newton's emission theory of light is TRUE and c'=c, Einstein's 1905 light postulate, FALSE: http://a-levelphysicstutor.com/wav-doppler.php "vO is the velocity of an observer moving towards the source. This velocity is independent of the motion of the source. Hence, the velocity of waves relative to the observer is c + vO. (...) The motion of an observer does not alter the wavelength. The increase in frequency is a result of the observer encountering more wavelengths in a given time." http://www.expo-db.be/ExposPrecedent...%20Doppler.pdf "La variation de la fréquence observée lorsqu'il y a mouvement relatif entre la source et l'observateur est appelée effet Doppler. (...) 6. Source immobile - Observateur en mouvement: La distance entre les crêtes, la longueur d'onde lambda ne change pas. Mais la vitesse des crêtes par rapport à l'observateur change !" http://www.hep.man.ac.uk/u/roger/PHY.../lecture18.pdf Roger Barlow: "Now suppose the source is fixed but the observer is moving towards the source, with speed v. In time t, ct/(lambda) waves pass a fixed point. A moving point adds another vt/(lambda). So f'=(c +v)/(lambda)." http://www.astrosurf.com/quasar95/exposes/redshift.pdf "Appliqué à la lumière, cet effet Doppler-Fizeau engendre un décalage des fréquences émises par une source en mouvement par rapport à un observateur. Comment expliquer ce phénomène ? Par un exemple simple : Une personne est debout sur le rivage d'un bord de la mer. Des vagues lui arrivent sur les pieds toutes les dix secondes. La personne marche, puis court en direction du large (là où se forment les vagues). Elle va à la rencontre des vagues, celles-ci l'atteignent avec une fréquence plus élevée (par exemple toutes les huit secondes, puis toutes les cinq secondes). La personne fait alors demi-tour et marche puis court en direction de la plage. Les vagues l'atteignent avec une fréquence moins élevée, par exemple toutes les douze, puis quinze secondes. Cette petite démonstration s'applique à une onde physique, comme un son, ou ici les vagues sur l'océan pour une meilleure compréhension. Elle peut être extrapolée à une onde lumineuse, en considérant que le sommet d'une vague est le point d'amplitude maximale de l'onde lumineuse." http://www.eng.uwi.tt/depts/elec/sta...relativity.pdf The Invalidation of a Sacred Principle of Modern Physics Stephan J.G. Gift "For a stationary observer O, the stationary light source S emits light at speed c, wavelength Lo, and frequency Fo given by Fo=c/Lo. If the observer moves toward S at speed v, then again based on classical analysis, the speed of light relative to the moving observer is (c + v) and not c as required by Einstein's law of light propagation. Hence the observer intercepts wave-fronts of light at a frequency fA, which is higher than Fo, as is observed, and is given by fA = (c+v)/Lo Fo. (...) In light of this elementary result invalidating STR, it is difficult to understand why this invalid theory has been (and continues to be) accepted for the past 100 years." If, as the observer starts moving towards the light source and wavecrests start hitting him more frequently, the frequency and the wavelength change while the speed of light (relative to the observer) remains constant, then c'=c+v predicted by Newton's emission theory of light is FALSE and c'=c, Einstein's 1905 light postulate, TRUE: http://www.pitt.edu/~jdnorton/teachi...ang/index.html John Norton: "Here's a light wave and an observer. If the observer were to hurry towards the source of the light, the observer would now pass wavecrests more frequently than the resting observer. That would mean that moving observer would find the frequency of the light to have increased (AND CORRESPONDINGLY FOR THE WAVELENGTH - THE DISTANCE BETWEEN CRESTS - TO HAVE DECREASED)."

David M. Harrison: "Einstein "Explains" the Michelson-Morley Experiment. When Einstein was 16, in 1895, he asked himself an interesting question: "If I pursue a beam of light with the velocity c I should observe such a beam of light as a spatially oscillatory electromagnetic field at rest. However, there seems to be no such thing, whether on the basis of experience or according to [the theory of electricity and magnetism]. From the very beginning it appeared to me intuitively clear that, judged from the standpoint of such an observer, everything would have to happen according to the same laws as for an observer who, relative to the earth, was at rest. For how, otherwise, should the first observer know, i.e.. be able to determine, that he is in a state of uniform motion?" -- As later written by Einstein in "Autobiographical Notes", in Schilpp, ed., Albert Einstein: Philosopher-Scientist. He continued to work on this question for 10 years with the mixture of concentration and determination that characterised much of his work. He published his answer in 1905: "... light is always propagated in empty space with a definite velocity c which is independent of the state of [relative] motion of the emitting body .... The introduction of a 'luminiferous ether' will be superfluous inasmuch as the view here to be developed will not require an 'absolutely stationary space' provided with special properties." -- Annalen Physik 17 (1905). Put another way, the speed of light is 1,079,253,000 km/hr with respect to all observers. As we shall see, this one statement is equivalent to all of the Special Theory of Relativity, and everything else is just a consequence. Notice that the statement also explains the null result of the Michelson-Morley experiment. However, although the evidence is not certain it seems quite likely that in 1905 Einstein was unaware of the experiment..." In the spirit of George Orwell's "1984", the most relevant slogan in Einsteiniana's schizophrenic world is: LIE IS TRUTH Einstein's 1905 light postulate by no means "explains the null result of the Michelson-Morley experiment". Rather, the experiment contradicts the light postulate and therefore refutes "all of the Special Theory of Relativity": http://philsci-archive.pitt.edu/1743/2/Norton.pdf John Norton: "In addition to his work as editor of the Einstein papers in finding source material, Stachel assembled the many small clues that reveal Einstein's serious consideration of an emission theory of light; and he gave us the crucial insight that Einstein regarded the Michelson-Morley experiment as evidence for the principle of relativity, whereas later writers almost universally use it as support for the light postulate of special relativity. Even today, this point needs emphasis. The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE." Pentcho Valev |
