Michael Wohlgenannt answered my question, but I still have the most important 
part unanswered.  LIGO is attempting to detect gravity waves by measuring the 
deformation of space caused by the passing wave by using laser interferometers 
in right angle configurations.  I understand that.  My question is this:  The 
passing gravity wave not only deformes space, but also TIME.  This is going to 
have an effect on the laser by changing its frequency as it passes, in effect 
changing the very measuring device trying to detect the very small change in 
dimensions of the arms of LIGO. 
I'm sure the scientist have taken this into consideration but I would like to
