I'm only coming back here very occasionally so don't count on any quick replies.-In the original post B-M wrote: "If you measure the time it takes for readings from the CMRB to reach a given point, then work backwards to a point where the time from CMRB X+,Y+,Z+ = X-,Y-,Z- you should have origin=X,Y,Z =0 which gives you a universal frame of reference."-This appears to be a misunderstanding of what the CMBR is. We are looking back in time to see microwave radiation emitted around 13.7 billion years ago. This should be more or less the same no matter where you are in the universe.-http://map.gsfc.nasa.gov/universe/bb_tests_cmb.html-To paraphrase: The CMBR fills the sky and can be detected everywhere we look. If we could see microwaves, the entire sky would glow with a brightness that was astonishingly uniform in every direction.-B-M appears to think the Background is the "edge" of a "present" spherical three-dimensional universe within which we are situated.
