Jul 13, 2019 · the Michelson-Morley experiment proves Earth isn't moving. The physical fact established by the Michelson-Morley experiment is that the speed of light at the surface of the earth is isotropic. This is the famous "null" result of the experiment.
- If somebody really tells you “the Michelson-Morley experiment proves Earth isn't moving”, ask them what observations of the Sagnac Effect say. At...
- Don't forget that the Michelson Morley setup is not the only way to look for possible variations of the speed of light with respect to other things...
- In 1999 E. J. Post showed the equivalence between the Michelson-Morley experiment and the Sagnac experiment. E. J. Post, A joint description of the...
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.

Research fields. Past experiments. Current experiments. Scientists. v. t. e. 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 between April and July 1887 ...
s1/ (c+v) + s1/ (c-v) =/= 2.s1/c. Thus, it does make a difference. However, that's not the important thing about the experiment, testing this only once would prove nothing, since you don't know the speed of Earth relative to the ether, nor the speed of light (with enough precision).

- Depends on who's observing. Suppose you're on the equator and sends a signal travelling both directions. Since you sent the signal simultaneously a...
- Failed for both those reasons. 1. If there was a universal frame of reference (ie. ether), then their experiment would have detected a change in sp...
- Let's say that in ether light would move at c. Also, consider Earth moving at a velocity v relative to the ether, and that, at some day, the ray th...
- You build in a mechanism that lets you make very small adjustments to the length, and you "tune" it before you start the experiment. It was very ch...
- Well, in those days I think the question was about "is there an ether that carries light waves or does light travel through space, which is a void:...
- I think the test was done in country-side room with mirrors in air. You are right. M-M exp assumed either could be detected in air. That could have...
- I think there was a suggestion that the Ether might 'stick' to the Earth as it moves and this is why we dont detect the wind. The wind moves around...
- Let's use an absurd example. You're in a zeppelin, travelling with an airspeed of 50 kph with a 49 kph wind at your back. So your groundspeed is 99...
- Yes, they will both be affected, but the effect is not the the same in the parallel direction as it is in the perpendicular direction.
- Do the math - let vy be your speed, and ve be the ether speed, both with respect to the ground. If distance s=vt, then t=s/v. So going out, _tg = s...
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.

Feb 27, 2019 · The Michelson-Morley experiment was an attempt to measure the motion of the Earth through the luminous ether. Though often called the Michelson-Morley experiment, the phrase actually refers to a series of experiments carried out by Albert Michelson in 1881 and then again (with better equipment) at Case Western University in 1887 along with chemist Edward Morley.
