It is argued that the small horizon when the Universe was close to the Planck temperature restricted the possible energies of elementary particles, preventing them from being in full thermal equilibrium. Grand unified particle interactions seem unlikely to have thermalized the universe much before the temperature fell to the mass scale of the baryon-number violation bosons. (14 refs)
