The same way we often use the Earth as a reference. The laws of physics are the same when moving inertially relative to the CMB as relative to the Earth or Moon. Brent 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. Brent Some parts actually moving relative to other parts? I never heard that claimed. Are you referring to the tiny temperature variations which have been measured? AG -- You received this message because you are subscribed to the Google Groups "Everything List" group.
