Michelson-Morley experiment

Definitions

    • n Michelson-Morley experiment a celebrated experiment conducted by Albert Michelson and Edward Morley; their failure to detect any influence of the earth's motion on the velocity of light was the starting point for Einstein's theory of relativity

The data from this experiment shows that De Witte had detected absolute motion of the earth through space, as had six earlier experiments, beginning with the Michelson-Morley experiment of 1887.
The Roland De Witte 1991 Detection of Absolute Motion and Gravitational Waves
This was despite the fact that the Michelson-Morley experiment did observe fringe shifts of the form indicative of such an anisotropy.
The Roland De Witte 1991 Detection of Absolute Motion and Gravitational Waves
However assuming exactly the same declination as Miller the speed observed by De Witte appears to be also in excellent agreement with the Miller speed, which in turn is in agreement with that from the Michelson-Morley and other experiments.
The Roland De Witte 1991 Detection of Absolute Motion and Gravitational Waves
Many experiments had been performed in an effort to detect the motion of the aether relative to Earth, with Michelson and Morley’s being just one of them, but they had all failed.
Some Comments on the Tests of General Relativity
So, by 1905, without the use of the four dimensional space-time, it had been shown how the null result of the Michelson-Morley experiment could be consistent with aether theory.
Some Comments on the Tests of General Relativity
These two kinds of experiments are sensitive to the one-way speed of light in contrast to the round-trip experiments as the Michelson-Morley one.

Also included for comparison is the corresponding limit obtained from Michelson-Morley type experiments.
The Confrontation between General Relativity and Experiment: A 1998 Update
We discussed the Michelson-Morley experiment that employs a single photon interferometer, and pointed out that this experiment demonstrates that interference is independent of the motion of the earth. We also proposed a means of interpretation of this experiment using de Broglie-Bohm picture.

These problems also apply to the famous measurements of Michelson and Morley, and to most if not all similar experiments; appendices are provided discussing several such experiments.
