## Abstract

This paper revises the theory of Michelson-Morley interferometer, exposing an error in the derivation of the formula for the propagation time of the light beam that moves perpendicular to the direction or Earth motion. It also shows that the Michelson-Morley null result can be fully explaned by the Fresnel formula for partial ether-drag. The Lorentz assumption of length contraction for one of the paths in the interferometer is redundant. So the Fresnel conept and the Lorentz concept are mutually exclusive, and therefore cannot be simultaneously present in a valid theory. The Fresnel concept is not at all denied by contemporary science, and is to be preferred. The elimination of the Lorentz concept might change our view of space and time.
