"The Omega Point Theory suggests that the particle physics Standard Model (SM) is sufficient to explain both [dark matter and dark energy]: the Dark Energy is just the currently uncancelled part of the positive cosmological constant, and the Dark Matter is just the Standard Model SU(2)_{left} field, coupled to the SM Higgs field. I was very worried when I wrote PHYSICS OF IMMORTALTIY that the entropy in the CMBR would make an acceleration in the collapsing phase of universal history impossible. I propose to solve this problem by claiming the temperature of the CMBR — currently "measured"... 2.2726 degrees — is actually... ! I show in a paper I put on the lanl data base (xxx.lanl.gov) last November that such an apparently ridiculous claim is possible, because any quantized gauge field in a homogeneous and isotropic universe would NECESSARILY have a Planckian spectrum, even at zero temperature! What the measurements of CMBR showing that it is Planckian... are really measuring... not the temperature, but the size of the universe. In my paper, I show how to convert the... "temperature" of 2.2726 into the size of the universe."
