how come xayma didn't pounce on this question
I don't have to pounce on every question.
But it didn't show that the aether was wrong. Merely that they got a null result.
From this they deduced that maybe length contracts in the direction of the aether wind. A large body such as the Earth drags the aether with it (which would have disrupted the viewing of stars so it couldn't occur).
It wasn't until Maxwell and his theories of electromagnetism, that the aether model was finally dispensed of. Although Einsteins thought experiements showed it was not needed it didn't explain the propagation of light waves.
