Default WHAT DID MICHELSON AND MORLEY REFUTE ?

Most Einsteinians deceitfully teach that the Michelson-Morley experiment has refuted the variable speed of light predicted by Newton's emission theory of light:

http://www.berkeleyscience.com/relativity.htm
"The conclusion of the Michelson-Morley experiment was that the speed of light was a constant c in any inertial frame. Why is this result so surprising? First, it invalidates the Galilean coordinate transformation. Note that with the frames as defined in the previous section, if light is travelling in the x' direction in frame O' with velocity c, then its speed in the O frame is, by the Galilean transform, c+v, not c as measured. This invalidates two thousand years of understanding of the nature of time and space. The only comparable discovery is the discovery that the earth isn't flat! The Michelson Morley experiment has inevitably brought about a profound change in our understanding of the world."

http://www.amazon.com/Faster-Than-Sp.../dp/0738205257
Faster Than the Speed of Light, Joao Magueijo: "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!"

The question "Why do Einsteinians lie?" is equivalent to "Why do dogs bark?" - it is pointless to discuss it. Another question makes more sense: If the Michelson-Morley experiment did not refute the variable speed of light predicted by Newton's emission theory of light, what did it refute? Other Einsteinians explain:

http://en.wikipedia.org/wiki/Michels...ley_experiment
"The Michelson-Morley experiment was published in 1887 by Albert A. Michelson and Edward W. Morley and performed at what is now Case Western Reserve University in Cleveland, Ohio. It attempted to detect the relative motion of matter through the stationary luminiferous aether ("aether wind"). The negative results are generally considered to be the first strong evidence against the then prevalent aether theory, and initiated a line of research that eventually led to special relativity..."

That is, the Michelson-Morley experiment refuted the ether theory. This means that Michelson and Morley took something from the ether theory, used it in their calculations, but in the end the calculations produced a wrong result - incompatible with the outcome of the experiment. To put it simply, the "something" proved false.

What was the "something" that Michelson and Morley took from the ether theory and used in their calculations? The principle of constancy of the speed of light of course ("the speed of light relative to the observer is independent of the speed of the light source"). The experiment refuted that principle as false in the first place, and only secondarily did it refute the ether theory as a whole:

https://www.physics.umn.edu/classes/...slides-SR1.pdf
University of Minnesota (Slides entitled: "History of special relativity I: debunking the myth of the Michelson-Morley experiment"): "The nail in the coffin of the myth [of the Michelson-Morley experiment]: Simple explanation of the result of Michelson and Morley is to assume that the velocity of light does depend on the velocity of the source. But that is the exact opposite of the light postulate!"

http://www.philoscience.unibe.ch/doc...S07/Norton.pdf
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: "The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE."

http://books.google.com/books?id=JokgnS1JtmMC
"Relativity and Its Roots" By Banesh Hoffmann, p.92: "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."

Einstein's schizophrenic world:

http://abyss.uoregon.edu/~js/glossar...on_morley.html
University of Oregon: "The Michelson-Morley experiment was an attempt to detect the velocity of the Earth with respect to the hypothetical luminiferous ether, a medium in space proposed to carry light waves. First performed in Berlin in 1881 by the physicist A.A. Michelson, the test was later refined in 1887 by Michelson and E.W. Morley in the United States. The procedure depended on a Michelson interferometer, a sensitive optical device that compares the optical path lengths for light moving in two mutually perpendicular directions. It was reasoned that, if the speed of light were constant with respect to the proposed ether through which the Earth was moving, that motion could be detected by comparing the speed of light in the direction of the Earth's motion and the speed of light at right angles to the Earth's motion. No difference was found. This null result seriously discredited the ether theories and ultimately led to the proposal by Albert Einstein in 1905 that the speed of light is a universal constant."

"if the speed of light were constant with respect to the proposed ether through which the Earth was moving"

is equivalent to:

"if the speed of light relative to the observer were independent of the speed of the light source"

On the other hand, Einstein's 1905 exact proposal was that the speed of light relative to the observer is independent of the speed of the light source.. So, essentially, the above text says the following:

The Michelson-Morley experiment was an attempt to detect the velocity of the Earth with respect to the hypothetical luminiferous ether, a medium in space proposed to carry light waves. First performed in Berlin in 1881 by the physicist A.A. Michelson, the test was later refined in 1887 by Michelson and E.W. Morley in the United States.

No difference was found. This null result seriously discredited the ether theories and ultimately led to the proposal by Albert Einstein in 1905 that the speed of light relative to the observer is independent of the speed of the light source.

Banesh Hoffmann, perhaps the cleverest Einsteinian, hinting at the idiocy:

http://books.google.com/books?id=JokgnS1JtmMC
"Relativity and Its Roots", 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.."

In 1911 Jean Perrin explains that the Michelson-Morley experiment is compatible with the variable speed of light predicted by Newton's emission theory of light; Paul Langevin agrees reluctantly:

http://www.sofrphilo.fr/telecharger.php?id=69
Séance du 19 Octobre 1911, LE TEMPS, L'ESPACE ET LA CAUSALITÉ DANS LA PHYSIQUE MODERNE
M. PERRIN. - Il est remarquable qu'un retour à l'hypothèse de l'émission, en admettant que les particules lumineuses sont émises par chaque source avec une même vitesse par rapport à elle dans toutes les directions expliquerait, dans les conceptions de la Mécanique classique, le résultat négatif de l'expérience de Michelson et Morley quel que soit le mouvement d'ensemble du système. D'autre part les physiciens, en développant la théorie des ondulations au point de vue du principe de relativité, sont amenés à conclure que la lumière est inerte et probablement pesante. N'est-ce pas un retour vers l'ancienne théorie de l'émission ?
M. LANGEVIN. - Tout d'abord la théorie de l'émission sous sa forme ancienne compatible avec la mécanique s'est montrée impuissante à expliquer les phénomènes les plus simples de l'optique en particulier la réfraction et les interférences utilisées dans l'expérience même de Michelson et Morley. Elle a dû être abandonnée depuis l'expérience cruciale de Foucault sur la vitesse de la lumière dans les milieux réfringents. S'il est vrai que par un singulier retour le principe de relativité conduise à reconnaître à la lumière des propriétés analogues à l'inertie et même à la pesanteur, une théorie de l'émission qui représenterait ces faits devrait être singulièrement différente de la théorie ancienne et devrait, pour tenir compte de la nature commune des phénomènes optiques et électromagnétiques expliquer aussi ces derniers phénomènes; et comme ceux-ci paraissent exactement régis par les équations des Maxwell, la nouvelle théorie devrait correspondre à l'espace et au temps dont les transformations conservent leur forme à ces équations, c'est-à-dire à l'espace et au temps du groupe de Lorentz. Il est d'ailleurs bien difficile de discuter une théorie non encore formulée.

In 1922 Paul Langevin explains that the Michelson-Morley experiment has gloriously confirmed the constancy of the speed of light; Jean Perrin agrees wholeheartedly:

http://www.scribd.com/doc/966376/La-...de-philosophie
Séance du 6 avril 1922, LA THÉORIE DE LA RELATIVITÉ
M. LANGEVIN. - (...) La théorie de la Relativité restreinte repose sur deux axiomes fondamentaux : le principe de relativité et le principe de la constance de la vitesse de la lumière. Selon le premier principe, les équations traduisant les lois qui régissent les phénomènes doivent avoir la même forme pour tous les systèmes d'inertie en translation uniforme les uns par rapport aux autres ; ce principe fondé sur l'expérience s'est toujours trouvé confirmé dans tous les domaines de la physique.. L'isotropie de la vitesse de la lumière, autrement dit la constance de c quand on passe d'un système galiléen à un autre, est une conséquence de ces lois de l'électromagnétisme que personne ne peut raisonnablement songer à contester, et se trouve directement vérifiée par des expériences du genre de celle de Michelson.
M. PERRIN. - Je m'associe entièrement aux vues de M. Langevin et pense que la théorie a la plus grosse importance dans tous les domaines de la physique.
