I understand that MM measured the speed of light with and perpendicular to Earth's motion looking for interference effect and didn't find one. But wouldn't the light waves be out of phase if there was only the tiniest difference in the length of the arms of the inferometer? Why weren't they out of phase if the 2 beams traveled slightly different distances?
