That's not a valid summary .. their experiment is consistent with that 
conclusion, but it did not show that that was the only explanation.  What it 
did rule out was an absolute fixed ether.

Shame that that is refuted by Sagnac.  Things would be much simpler if the 
universe actually behaved that way.  But wedont' get to choose the way the 
universe works.
