What was the objective of the MME?
Did the Lorentz contraction actually explain the null result of the MME?

The Michelson-Morely experiment was set up to test the (at the time) rather unexpected prediction of Maxwell's equations that the speed of light in vacuum is constant and independant of the frame of reference.HannonRJ said:What was the objective of the MME?

The original objective was to show that the speed of light was different moving in the direction of the hypothetical ether wind than it would be moving across at a right angle to the ether wind. If ether really existed, it would be unreasonable to believe that it travels along with the earth at all times of the year. You would expect the planet to be moving through it at some time of the year, if not all the time.HannonRJ said:What was the objective of the MME?
Since the observers were moving along with the apparatus, I don't think so.Did the Lorentz contraction actually explain the null result of the MME?
the only curiosity to me is why they would expect the "the relative velocity of the earth and the ether [to be] certainly less than one-fourth" earth's orbital velocity at all times of the year. if the earth happened to be moving along with the ether wind in spring, it should be moving rapidly through it in the fall. the only reason to suspect not would be some wild theory that the ether wind moves along side of the earth wherever it is, as if the earth is the center of all things.HannonRJ said:According to M+M, the purpose of their experiment was to test the validity of Fresnel's hypothesis that "the ether is supposed to be at rest except in the interior of transparent media." M+M concluded that their experiment indicated that, "...the relative velocity of the earth and the ether is probably less than one sixth of the earth's orbital velocity, and certainly less than one-fourth".[The American Journal of Science, No. 203, Nov. 1887, p333.]
i have absolutely no idea why anyone would be applying any Lorentz transformation to the experiment at all. is the observer moving relative to the apparatus?If one applies the Lorentz contraction to M+M's math (in the cited article), it does not explain the results of the experiment.
isn't the ostensible answer obvious? you need to read what responses given you previously.Why did the MME produce the result that it did?
The question relates to the Lorentz contraction (actually first thought up by Fitzgerald, so it is also known as the Fitzgerald-Lorentz contraction), not the Lorentz transformation. The Fitzgerald- Lorentz contraction did explain the MME result. The problem was that no one could explain why distances would contract in the direction of the motion through the ether by exactly the right amount needed to make the speed of light appear to be equal in all directions.rbj said:i have absolutely no idea why anyone would be applying any Lorentz transformation to the experiment at all. is the observer moving relative to the apparatus?
