[A 2] Of this experiment, Albert Einstein wrote, "If the Michelson–Morley experiment had not brought us into serious embarrassment, no one would have regarded the relativity theory as a (halfway) redemption." [A 3]: 219 Michelson–Morley type experiments have been repeated many times with steadily increasing sensitivity.
Edward Williams Morley (January 29, 1838 – February 24, 1923) was an American scientist known for his precise and accurate measurement of the atomic weight of oxygen, and for the Michelson–Morley experiment.
The Michelson–Morley experiment was conducted in 1887 by physicist Albert A. Michelson of Case School of Applied Science and chemist Edward W. Morley of Western Reserve University. This experiment proved the non-existence of the luminiferous ether and was later cited as circumstantial evidence in support of special relativity as proposed by ...
Albert Abraham Michelson (surname pronunciation anglicized as Michael-son; December 19, 1852 – May 9, 1931) was an American physicist known for his work on measuring the speed of light and especially for the Michelson–Morley experiment.

In this theory, the reason that the Michelson–Morley experiment "failed" was that the apparatus contracted in length in the direction of travel. That is, the light was being affected in the "natural" manner by its travel through the aether as predicted, but so was the apparatus itself, cancelling out any difference when measured.
Shankland's report on the Albert A. Michelson's Irvine Ranch experiments was published in 1953. In the British journal Nature, Shankland gave the historical background of how Einstein formulates the first two principles, in 1905, of the special theory of relativity from the Michelson–Morley experiment. Shankland believed that the accepted ...
A big challenge for the Lorentz ether theory was the Michelson–Morley experiment in 1887. According to the theories of Fresnel and Lorentz, a relative motion to an immobile aether had to be determined by this experiment; however, the result was negative.
