POSTSCIENTISM: DOUBLE-EDGED EXPERIMENTS
Normally Einsteinians teach that both the Michelson-Morley experiment
and the Pound-Rebka experiment have gloriously confirmed Divine Albert's Divine Theory. This of course implies that the two experiments are compatible with Einstein's 1905 light postulate stating that the speed of light does not vary with the speed of the emitter. Yet occasionally Einsteiniana's priests admit that the two experiments are equally compatible with the antithesis of the light postulate, the equation c'=c+v given by Newton's emission theory of light and showing how the speed of light varies with v, the speed of the emitter relative to the observer: http://groups.google.com/group/sci.p...abc7dbb30db6c2 John Norton (Einsteiniana's high priest): "THE MICHELSON-MORLEY EXPERIMENT IS FULLY COMPATIBLE WITH AN EMISSION THEORY OF LIGHT THAT CONTRADICTS THE LIGHT POSTULATE." Tom Roberts (Einsteiniana's priest): "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." Clearly in the era of Postscientism experiments have acquired the property of being compatible with both the statement: "The speed of light does not vary with the speed of the emitter" and its antithesis: "The speed of light does vary with the speed of the emitter" Also, since at least two experiments are double-edged, any experiment is presumably double-edged in the era of Postscientism. The experimental verification of Einstein's 1905 light postulate is therefore pointless; it is much more reasonable to simply decree that Einstein's 1905 light postulate be true by definition: http://math.ucr.edu/home/baez/physic..._of_light.html Steve Carlip (Einsteiniana's high priest): "Is c, the speed of light in vacuum, constant? At the 1983 Conference Generale des Poids et Mesures, the following SI (Systeme International) definition of the metre was adopted: The metre is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second. This defines the speed of light in vacuum to be exactly 299,792,458 m/ s. This provides a very short answer to the question "Is c constant": Yes, c is constant by definition!" Pentcho Valev |

POSTSCIENTISM: DOUBLE-EDGED EXPERIMENTS
Lunacy generated by double-edged experiments:
http://www.amazon.com/Faster-Than-Sp.../dp/0738205257 Joao Magueijo: "I am by profession a theoretical physicist. By every definition I am a fully credentialed scholar-graduate work and Ph.D. at Cambridge, followed by a very prestigious research fellowship at St. John's College, Cambridge (Paul Dirac and Abdus Salam formerly held this fellowship), then a Royal Society research fellow. Now I'm a lecturer (the equivalent of a tenured professor in the United States) at Imperial College. (...) A missile fired from a plane moves faster than one fired from the ground because the plane's speed adds to the missile's speed. If I throw something forward on a moving train, its speed with respect to the platform is the speed of that object plus that of the train. You might think that the same should happen to light: Light flashed from a train should travel faster. However, what the Michelson-Morley experiments showed was that this was not the case: Light always moves stubbornly at the same speed. This means that if I take a light ray and ask several observers moving with respect to each other to measure the speed of this light ray, they will all agree on the same apparent speed! Einstein's 1905 special theory of relativity was in part a response to this astonishing result. What Einstein realized was that if c did not change, then something else had to give. That something was the idea of universal and unchanging space and time. This is deeply, maddeningly counterintuitive. In our everyday lives, space and time are perceived as rigid and universal. Instead, Einstein conceived of space and time-space-time-as a thing that could flex and change, expanding and shrinking according to the relative motions of the observer and the thing observed. The only aspect of the universe that didn't change was the speed of light. And ever since, 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. Hundreds of experiments have verified this basic tenet, and the theory of relativity has become central to our understanding of how the universe works." Magueijo is surely aware of this: http://books.google.com/books?id=JokgnS1JtmMC "Relativity and Its Roots" By Banesh Hoffmann "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." http://philsci-archive.pitt.edu/arch.../02/Norton.pdf John Norton: "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......THE MICHELSON-MORLEY EXPERIMENT IS FULLY COMPATIBLE WITH AN EMISSION THEORY OF LIGHT THAT CONTRADICTS THE LIGHT POSTULATE." http://www.pitt.edu/~jdnorton/papers/companion.doc 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." The explanation "Magueijo is lying about the Michelson-Morley experiment" would be too simplistic. He is just exercising himself in doublethink: http://www.liferesearchuniversal.com...html#seventeen George Orwell: "Doublethink means the power of holding two contradictory beliefs in one's mind simultaneously, and accepting both of them. The Party intellectual knows in which direction his memories must be altered; he therefore knows that he is playing tricks with reality; but by the exercise of doublethink he also satisfies himself that reality is not violated. The process has to be conscious, or it would not be carried out with sufficient precision, but it also has to be unconscious, or it would bring with it a feeling of falsity and hence of guilt. Doublethink lies at the very heart of Ingsoc, since the essential act of the Party is to use conscious deception while retaining the firmness of purpose that goes with complete honesty. To tell deliberate lies while genuinely believing in them, to forget any fact that has become inconvenient, and then, when it becomes necessary again, to draw it back from oblivion for just so long as it is needed, to deny the existence of objective reality and all the while to take account of the reality which one denies - all this is indispensably necessary. Even in using the word doublethink it is necessary to exercise doublethink. For by using the word one admits that one is tampering with reality; by a fresh act of doublethink one erases this knowledge ; and so on indefinitely, with the lie always one leap ahead of the truth. (...) It need hardly be said that the subtlest practitioners of doublethink are those who invented doublethink and know that it is a vast system of mental cheating. In our society, those who have the best knowledge of what is happening are also those who are furthest from seeing the world as it is. In general, the greater the understanding, the greater the delusion ; the more intelligent, the less sane." Pentcho Valev |

Two points, Pentcho, not that you care... 1. The 1905 postulate is a statement of SPECIAL relativity, not of general relativity. It applies to INERTIAL frames, not to frames at different gravitational potentials. What you are doing is akin to applying Newton's 1st law of motion to a case where an object is clearly accelerating. That is pilot error, not a problem with the theory. 2. The Michelson-Morley experiment is also compatible with a ballistic theory of light. The fact that Michelson-Morley's experiment supports relativity is NOT the same as saying that it supports relativity at the exclusion of all other possible theories. If you have it in your head that an experiment can support one and only one theory at the exclusion of all others, then you just need to correct that simple mistake in your head. |

POSTSCIENTISM: DOUBLE-EDGED EXPERIMENTS
If it were not for the postscientific schizophrenia, the frequency
shift f'=f(1+gh/c^2) measured by Pound and Rebka would just be a manifestation of the variation of the speed of light: c'=c(1+gh/c^2) predicted by Newton's emission theory of light, in accordance with the formula: (frequency) = (speed of light)/(wavelength) In the era of Postscientism this interpretation of the Pound-Rebka experiment is a grand secret between Einsteiniana's priests. Believers should know something different: the frequency shift f'=f(1+gh/c^2) is a glorious manifestation of Einstein's discovery that upstairs time moves faster than downstairs: http://student.fizika.org/~jsisko/Kn...Morin/CH13.PDF David Morin: "The equivalence principle has a striking consequence concerning the behavior of clocks in a gravitational field. It implies that higher clocks run faster than lower clocks. If you put a watch on top of a tower, and then stand on the ground, you will see the watch on the tower tick faster than an identical watch on your wrist. When you take the watch down and compare it to the one on your wrist, it will show more time elapsed."

POSTSCIENTISM: DOUBLE-EDGED EXPERIMENTS
More blatant lies about the Michelson-Morley experiment (or just
exercises in doublethink): http://arxiv.org/ftp/arxiv/papers/1011/1011.1318.pdf Farid Ahmed, Brendan M. Quine, Stoyan Sargoytchev, A. D. Staufferb: "The great precision Michelson-Morley experiment is beautiful in its simplicity, but it tests only the constancy of the round-trip averaged speed of light. So, based on the results of the classic or modern tests of Michelson-Morley experiment as shown in the in Fig.6, we can establish the special theory of relativity only for the round-trip averaged speed of light." http://www.hawking.org.uk/index.php?...64&It emid=66 Stephen Hawking: "Interestingly enough, Laplace himself wrote a paper in 1799 on how some stars could have a gravitational field so strong that light could not escape, but would be dragged back onto the star. He even calculated that a star of the same density as the Sun, but two hundred and fifty times the size, would have this property. But although Laplace may not have realised it, the same idea had been put forward 16 years earlier by a Cambridge man, John Mitchell, in a paper in the Philosophical Transactions of the Royal Society. Both Mitchell and Laplace thought of light as consisting of particles, rather like cannon balls, that could be slowed down by gravity, and made to fall back on the star. But a famous experiment, carried out by two Americans, Michelson and Morley in 1887, showed that light always travelled at a speed of one hundred and eighty six thousand miles a second, no matter where it came from. How then could gravity slow down light, and make it fall back." http://205.188.238.109/time/time100/...of_rela6a.html Stephen Hawking: "So if you were traveling in the same direction as the light, you would expect that its speed would appear to be lower, and if you were traveling in the opposite direction to the light, that its speed would appear to be higher. Yet a series of experiments failed to find any evidence for differences in speed due to motion through the ether. The most careful and accurate of these experiments was carried out by Albert Michelson and Edward Morley at the Case Institute in Cleveland, Ohio, in 1887......It was as if light always traveled at the same speed relative to you, no matter how you were moving." http://www.techno-science.net/?ongle...efinition=1711 "En effet, dès la fin du XIXe siècle, diverses expériences (notamment, celle de Michelson) et observations laissaient apparaître une vitesse de la lumière dans le vide identique dans tous les repères inertiels." http://www.pauljorion.com/blog/?p=9459 Paul Jorion: "Ce que Michelson et Morley parvinrent à établir grâce à l'expérience qu'ils réalisèrent en 1887 (Michelson la répéterait en 1897 à lUniversité de Chicago où il enseignait désormais), c'est que le principe newtonien ne s'applique pas à la lumière. Imaginons cette fois, que vous vous trouvez sur le toit d'un vaisseau intergalactique se déplaçant dans l'espace à la moitié de la vitesse de la lumière et que vous dirigez le faisceau de lumière émanant d'une torche d'un modèle courant dans la direction où progresse le vaisseau stellaire. Si le principe newtonien d'addition des vitesses s'appliquait à la lumière émanant de votre torche, elle voyagerait maintenant à une vitesse égale à une fois et demie celle de la lumière. Or, ce que l'« expérience cruciale » de Michelson et Morley révéla, c'est que ce n'est pas le cas : le principe d'additivité des vitesses ne s'applique pas : quelle que soit la vitesse à laquelle se déplace l'émetteur de lumière, la vitesse de la lumière dans le faisceau émis est c : 300 000 kilomètres par seconde, ni plus ni moins. Autrement dit, la vitesse de la lumière est constante (c représente en fait la vitesse de la lumière dans un vide)." http://philosophie.initiation.cours....-48902702.html "A la fin du XIXème siècle, les travaux de deux physiciens, Michelson et Morley, mirent en évidence le constat suivant : quelque soit le référentiel utilisé, la vitesse de la lumière est constante, ce qui est en totale contradiction avec la vision classique ayant cours à leur époque." http://www.sciences.univ-nantes.fr/p...at/51relat.htm Claude SAINT-BLANQUET, Maître de conférences: "Compte tenu des résultats de l'expérience de Michelson et Morley, on doit renoncer à la transformation de Galilée."
