I'd really like to see where the Lorentz contraction was measured. If it can be measured, one can go back and properly redo Michelson-Morley and measure the anisotropy of c.

Michelson-Morely is how we can measure Lorentz contraction. Three things have to come into play to produce a null result in that experiment: the finite speed of light, time dilation, and Lorentz contraction. Now that we can independently measure the first two to a high degree of accuracy, we can take the MM experiment as a test of Lorentz contraction. As predicted by relativity, it is exactly as much as it needs to be to cancel the influence of the first two effects on the interferometer.

That was good. Very good.

The MM experiment was performed in an accelerated reference frame, on the surface of the rotating earth. If the velocity of light is known to a high degree, how come east-west and west-east transit times over the same path (but opposite directions) are not equal?
