Michelson–Morley experiment. For interference experiments on matter, see Hughes–Drever experiment. The Michelson–Morley experiment was an attempt to measure the motion of the Earth relative to the luminiferous aether, [A 1] a supposed medium permeating space that was thought to be the carrier of light waves. The experiment was performed ...
Jun 14, 2024 · Michelson-Morley experiment, an attempt to detect the velocity of Earth with respect to the hypothetical luminiferous ether, a medium in space proposed to carry light waves. First performed in Germany in 1880–81 by the physicist A.A. Michelson , the test was later refined in 1887 by Michelson and Edward W. Morley in the United States .

Jun 11, 2024 · Light - Michelson-Morley, Experiment, Wave-Particle: The German-born American physicist A.A. Michelson set the early standard for measurements of the speed of light in the late 1870s, determining a speed within 0.02 percent of the modern value. Michelson’s most noteworthy measurements of the speed of light, however, were yet to come. From the first speculations on the wave nature of light by ...
May 9, 2020 · The Michelson-Morley experiment was performed by American scientists Albert Michelson and Edward Morley between April and July 1887. The purpose of this experiment is to prove the existence of ether. This hypothetical medium permeating space was thought to be the carrier of light waves. This experiment aimed to measure the speed of light in two ...

By the end of the 1800s, the dominant theory of how light worked was that it was a wave of electromagnetic energy, because of experiments such as Young's double slit experiment. The problem is that a wave had to move through some sort of medium. Something has to be there to do the waving. Light was known to travel through outer space (which scienti...
The result was disappointing because they found absolutely no evidence of the relative motion bias they were looking for. No matter which path the beam took, light seemed to be moving at precisely the same speed. These results were published in 1887. One other way to interpret the results at the time was to assume that the ether was somehow connect...

The Michelson Morley Experiment was one of the failed experiments that stands as proof against the existence of the luminiferous ether concept. Michelson and Morley tried to explain that Earth moved around the sun on its orbit, and the flow of substances like ether across the Earth’s surface could produce a detectable “ether wind”.

First off, the Michelson-Morley experiment ran in 1887. It did find a small positive effect (not the null or zero effect often mentioned) Second, between 1906 and mid-1930s, Dayton Miller ran a series of experiments that did find solid positive results for ether 'wind.'.
