The role of primordial black holes in the very early Universe under SU(3)×SU(2)×U(1), SU(5), and their supersymmetric counterparts is investigated. It is found that three of the four theories predict a phase, beginning around the Planck time and ending sometime on the order of ten to a hundred Planck times, in which black holes and radiation are comparable energy density. The fourth theory, SU(5), predicts a radiation-dominated model from the Planck era onward. © 1989 The American Physical Society.
