I'm assuming, as Physicist said, that the Lorentz contraction can be measured from the MM experiment. I'm having trouble with the v/c term. What v do I use? Are you saying v is zero? If it's zero, then where is the contraction? There's no relative motion between the light source, apparatus and observer. What is the causitive agent of the contraction? I believe that v was the velocity of the frame of reference (that is, the earth) in its motion around the sun.
So we can neglect the rotational velocity at the surface of the earth due to its rotation?
