Negative Result Of Michelson Morley Experiment. Though the ultimate result was negative the experiment key in that it opened the door for. The above experiment shows that the speed of light is constant in space irrespective of the direction and speed of inertial frame.
Another suggestion to explain the negative result of the Michelson-Morley experiment was the idea that the Earth drags the ether along with it as it orbits the sun galactic center etc. Michelson and Morley did not find any significant difference between the speed of light in the direction of the presumed ether and the speed at right angles. Almost two decades after the Michelson-Morley experiment in 1905 Albert Einstein published a paper which explained its puzzling results.
It attempted to detect the relative motion of matter through the stationary luminiferous aether aether wind.
The negative results are generally considered to be the first strong evidence against the then. Michelson the test was later refined in 1887 by Michelson and Edward W. Morley in the United States. As the theoretical results of the M-M experiment did not match with the experimental results Theoretically fringe shift result was not zero it was about 04 but the experimentally it was 0.
