Uniformity of universe expansion

  1. Oct 2, 2009 #1
    As far as I understand, the justifications for the uniformity of the expansion of the visible universe comes from the CMBR and from the uniformity of the red shift around us. However, I was wondering whether theoretically one could make an interferometer sensitive enough to measure this: the sensitivity of the Michelson Morley interferometer was enough to measure differences of the speed of light with respect to the vacuum, but it would need greater sensitivity to see whether, assuming this result, the expansion of space would make a difference in different directions. Is this an unrealizable thought experiment, or is the thought experiment itself faulty?
