Michelson made a mistake in his calculations, he assumed the phase shift was only proportional to the time the wave needs to travel the distance L. But in reality phase shift is proportional to the distance from the source (how many wavelengths fit in that distance)
It is proportional to the time only in stationary case in which the distance is given by c*t in case of ligth.
Since there was no significant phase shift at any time, how could a mistake in calculation have any effect on the outcome of the experiment?
