The Michelson–Morley experiment was an attempt to measure the motion of the Earth relative to the luminiferous aether, a supposed medium permeating space that was thought to be the carrier of light waves.
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. No such velocity was detected, and this result seriously discredited ether theories.

Material from a York University course by Prof. Byron E. Wall provides a good summary of the Michelson-Morley experiment and its result. Below are slides that tell the story. Interested readers should feel free to go through the entire slide deck. Course Description (Archive) Full Slideshow (.ppt Archive) Note: Aether Drag Hypothesis was later reje...
Since 1887 the Michelson-Morley experiment has been repeated and verified on many occasions, with several different methodologies. The Michelson-Morley Wikipedia article (Archive) maintains a list of subsequent experiments. A 2009 repetition of the experiment is described below:
In a lecture titled How I Created the Theory of Relativity (Archive) Albert Einstein points this experiment out as a basis on developing Special Relativity: “ I was familiar with the strange results of Michelson’s experiment while I was still a student pondering these problems, and instinctively realized that, if we accepted his result as a fact, i...

In 1887 Albert A. Michelson (1852-1931) and Edward W. Morley (1838-1923) performed what has become one of the most famous physics experiments in history. Using an extremely sensitive optical instrument—the interferometer—they attempted to measure Earth's velocity with respect to the luminiferous ether, a hypothetical substance that most ...
Jul 12, 1987 · On July 12, 1887 Albert A. Michelson and Edward W Morley made the final measurements in an experiment that inadvertently changed forever the way we view the workings of the universe. The pair hoped to prove the existence of the ether—the invisible fluid thought to permeate the universe and to serve as the medium through which light waves travel.
At the heart of the experiment was an interferometer—a device invented by Michelson—which utilized the interference of light waves to perform measurements of incredible precision. Although an identical experiment undertaken by Michelson at Potsdam in 1880-81 failed to detect any motion of the earth relative to the ether, leading physicists ...
Dec 5, 2015 · In 1887, Michelson and Morley set up an experiment to prove that an ether existed and to understand its motion relative to the Earth. The purpose of the experiment was to study the speed of light in different directions.
