Abstract
Extrapolating the measured mass density of the universe to near a time when the universe’s mass converged 13.7 BYA, suggests temperatures and densities reached unimaginably high values. Extrapolation of the radiation (photon) density of the universe to this time indicates that the radiation-energy density dominated the mass-energy density in an explosive fire ball.
