In 1887 two American scientists, physicist Albert Michelson and physical chemist Edward Morley, performed an experiment that was designed to detect the motion of Earth through a hypothetical medium known as the luminiferous ether, which was thought to be present throughout space. They made their measurements with a very sensitive optical instrument now called a Michelson interferometer. Their observations showed no indication of movement through the predicted ether. This outcome was unexpected and has become one of the fundamental experimental results in support of the theory of special relativity, developed by Albert Einstein in 1905.

Michelson-Morley experiment An experiment, conducted in 1887 by the US physicists Albert Michelson (1852-1931) and Edward Motley (1838-1923), that attempted to measure the velocity of the earth through the ether. Using a modified Michelson interferometer (see illustration) they expected to observe a shift in the interference fringes formed when the instrument was rotated through 90°, showing that the speed of light measured in the direction of the earth s rota-... 

In 1881 the American physicist Albert Michelson and in 1887 with Edward Morley carried out some experiments showing that the speed of light is the same in the directions perpendicular and parallel to the Earth s orbit, i.e. the Earth s orbital velocity did not change the speed of light with respect to the Earth. The results were published in American Journal...
