Two-way speed of light and Lorentz-FitzGerald’s contraction in aether theory<\/strong> \/ Dr. Joseph Levy. – [Frankreich],\u00a012 S.\u00a0 URL: http:\/\/arxiv.org\/pdf\/physics\/0603267<\/span><\/strong><\/a>
\n<\/strong>Updated version of "How the apparent speed of light invariance follows from Lorentz contraction", International Meeting "Physical Interpretations of Relativity Theory" (PIRT), 7. 2000 (15.-18.9.), Imperial College, University of London. Late papers, p. 175.<\/p>\n

This paper aims at demonstrating that:
\n1\/ Assuming the equality of the two-way transit time of light in vacuo, along the two perpendicular arms of Michelson\u2019s interferometers (modern versions of Michelson\u2019s experiment), and the anisotropy of the one-way speed of light in the Earth frame, two facts supported today by strong experimental arguments, length contraction (in Lorentz and FitzGerald\u2019s approach) should no longer be regarded as an ad hoc hypothesis, it appears necessary and can be easily deduced.
\n2\/ Builder and Prokhovnik had the great merit of having shown that, as a result of to length contraction, the two-way transit time of light along a rod is the same in all directions in space <\/em>(and not only in two privileged directions). We agree with these authors up to this point, but, contrary to what is often believed, their approach failed to reconcile aether theory with the invariance of the apparent <\/em>(measured) two-way speed of light. Yet, as we shall show, due to the systematic measurement distortions entailed by length contraction and clock retardation assumed by aether theory, the two-way speed of light, although anisotropic and dependent on the absolute speed of the frame where it is measured, is always found equal to C. The reasons of this paradoxical but important result will be developed here. They confirm Lorentz-Fitzgerald\u2019s contraction and lend support of the existence of a preferred aether frame.<\/p>\n

I. Introduction.
\n<\/strong>Since the early days of relativity theory, Lorentz-FitzGerald\u2019s contraction has been the focus of adebate which is still lively today, and divides physicists in opposite camps.\n<\/p>\n

Some regard length contraction (L.C) as a na\u00efve opinion, for example Wesley 1<\/sup>, Phipps 2<\/sup>, Cornille 3<\/sup>, Galeczki 4<\/sup>. Some others consider it as a fundamental process which explains a lot of experimental facts. Among them Bell 5<\/sup>, Selleri 6<\/sup>, Builder, Prokhovnik 7<\/sup>, Dishington 8<\/sup>, Mansouri and Sexl 9<\/sup>, Wilhelm 10a<\/sup>.<\/p>\n

Length contraction has been proposed by Lorentz and FitzGerald 11<\/sup> in order to explain the null result of Michelson\u2019s experiment. (In fact the result was not completely null, but much smaller than the result expected. We know today that a completely null result can only be observed in vacuum experiments, see later).<\/p>\n
