Summary

The three observed particle interactions (electromagnetic, weak and strong) are thought to be low energy remnants of a unified theory (gauge symmetry group G) spontaneously broken at two energy scales MU ∼ 1015 GeV and MWS ∼ 102 GeV: [Display Equation] Finite temperature calculations show that in a cooling Universe these symmetry levels become a temporal sequence, with two phase transitions at temperatures of order MU and MWS.

In this paper we review unified interactions and their phase transitions (PTs) , which may considerably change the standard picture of the earliest Universe. Then we consider the impact of PTs on 1) the creation of the observed matter-antimatter asymmetry, 2) the origin of the density perturbations required for galaxy formation, and 3) the related problem of the creation of (too many) monopoles. It appears that 1) and perhaps 3) can be dealt with, provided the PTs, especially the first order ones, preserve the homogeneity of the Universe But 2) probably arises from the unknown epoch of quantum gravity importance.Je m ’accomrr!ode assez3 pour' moi3 des petits corps; Mais le mdde à souffrir me semble difficile3 Et Je Jou~e bien mieu:c la matière subtile.
