The Virgo stuff seems to imply that the CMB may not be cosmological. Actually, if the CMB photons were not generated at z~1000 this would invalidate the BB framework since this is a central pillar of the BB theory. As the universe expanded, it cooled. The primordial plasma had a temperature of 3000K, but as a result of the expansion of the universe it has cooled to a chilly 2.7K. In 1991 the COBE satellite found the CMB radiation has a precise blackbody spectrum, exactly as the hot big bang had predicted.I don't know where you got the idea that the Virgo stuff would somehow invalidate the entire BB framework.
Zahl mentions DASI. Here is a quote from the DASI team:
So, although we not be able to accurately deduce the cosmological parameters from polarization at the moment, the detection of the E-modes strongly support the notion that the majority of CMB photons came from z~1000.The shape and amplitude of the detected E-mode angular power spectrum are in agreement with theoretical predictions based on CMB temperature measurements. These results lend strong support to the underlying framework for the generation of the CMB anisotropy....
Sticking to this threads main topic, some of us have decided it may be a good idea to collectively email them (see JohnL's posts). Zahl, have you tried emailing the WMAP site lately?
