The
Michelson-Morley, Sagnac, and Michelson-Gale experiments.
Introduction
The introductory note to a recent series of
articles dedicated to the first centenary
of Michelson and Morley's experiment is of the
opinion that, "the 1887 experiment is commonly
hailed as the 'experimentum crucis' that made
necessary a revolution in our understanding
of space and time" [1], a clear reference
to the Einsteinian Theory of Relativity.
Immediately afterwards, L. S. Swenson Jr., when
reviewing Michelson's most significant experiments,
after lingering over the negative result of
the experiment carried out in 1887 attempting
to test the effect of the Earth's orbital velocity
on the velocity of light, carefully noted that
Michelson and Morley, "in their supplement
to that classical paper (of 1887) offered at
least seven ideas - four possibilities for laboratories
and three for observatories - for attacking
all over again the problem of the motion of
the whole Solar System through space" [2].
Yet he did not mention that the offshoot of
one of these ideas, "the attempt at a large
field in Clearing, Illinois to measure the effect
of the Earth's rotation on the velocity of light"
[2], an attempt better known as the "Michelson-Gale
experiment", did in fact have a positive
result.
Oversights and gross mystifications of this
kind are encountered in many scientific texts;
not only those on Michelson's experiments but
also on other experiments carried out with the
same purpose, such as laboratory attempts carried
out by Sagnac and other authors to measure the
effects of the various motions of the Earth
in Maxwell's Aether.
I consequently consider that an accurate, detailed
historical and scientific analysis of these
experiments and of their physical significance
is necessary.
Note
In this paper I was considering, following many textbooks, that the Michelson-Morley experiment had A NULL RESULT.
Later, having read the original papers of Michelson (1881), Michelson-Morley(1887), Morley Miller (1902-1905) and Miller (1925), I could see that Michelson-Morley experiment NEVER HAD A NULL RESULT.
Consequently the first part of this paper, in which I was considering various hypotheses to explain the NULL RESULT of Michelson-Morley, is simply a Non Sense.
Following a wrong information I was simply completely wrong.
Moreover, at the time of this paper, I had no information about the Optical Gyroscope which shows that Δ TF Δ TR
; the experimental contradiction of Einstein�s postulate:
Δ TF = Δ TR
