A thought just came to me while considering alternate explanations for the CMB. Dark matter is assumed to be distributed throughout the universe and is supposed to clump together around galaxy centers and other large massive objects. I have long wondered how this congregation of material could occur in matter that has no way to release the gravitational energy by radiation as with normal matter. Perhaps the CMB is generated gradually by the condensation of the dark matter. Or . perhaps dark matter is another aspect of the Dirac Sea ? http://arxiv.org/ftp/arxiv/papers/0705/0705.2908.pdf
