Abstract

The influence of the Grand Unification scale on the thermal history of the early Universe is discussed. Above M≈6.8·1015 GeV the irreversibilities seem to be too strong to ignore them, and the usual calculations lose their validity. Therefore at such scale parameters the low upper bound yielded by observations for the monopole entropy ratio is not neccessarily a counterevidence against the minimal SU(5) GUT.
