There's nothing "absolute" about the CMB.  It's just a widely available

relative to the Earth or Moon.

What does "absolute" mean? 

It would mean that the laws of physics were special in some sense, e.g. 
took a special form, in an *absolutely* stationary state.


It sure seems as absolute as anyone can imagine; the same everywhere in the 
universe. AG 

No.  It's just something that can be used as a reference, as could any 
other frame in inertial motion.  And it's not even a perfect reference 
since some parts move relative to others.

I didn't think it was a problem for SR since it's not the luminiferous 
ether which was thought to be the only frame in which light speed was a 
constant. I gave the problem to Quentin as an exercise to take his mind off 
irrelevancies. AG

 Since the CMBR defines a frame of absolute rest, how does this effect 
Special Relativity, if at all? AG
