To be more precise The MMexperiment should distinguisch between the stationary aether model of Fresnel and the draggedalong aether model of Stokes see History of special relativityThe search for the ether Michelson at first  believed that Stokes model was confirmed but in  he already knew that Stokes mode violates the law of aberration That was the starting point for Lorentz Poincare etc However it was shown by Einstein that all those develepments makes the ether and the classical concepts of space and time useless BTW Maxwells himself left only a few statements of the relative motion of aether and matter see his article Ether from
