    Edgar,

    Everything you describe above is consistent with coordinate time (which is 
equal to
    the time reported by a clock at absolute rest). The problem then becomes 
defining
    some reference for absolute rest...

    You can do it, but it won't explain anything that is not already accounted 
for by
    relativity.


Ooh, please sir, I know what it is!

I suggested the CMB might define Edgar's absolute rest frame :-)

Hey, I suggested it first. :-)

But the thing about the CMB rest frame is that it's position dependent due to expansion of the universe. Just look at Ned Wright's diagrams. So it's not a single inertial frame, it's an epoch at which the proper time to the big-bang is the same for all the stuff that's always been locally stationary.
