"If the CP domain structure is stretched to astronomical size by a subsequent period of moderate inflation, then, following , s may survive as galaxies in some regions of the universe and antibaryons may survive as antigalaxies in other regions. In this case, we have a "local" matter-antimatter asymmetry instead of a global one. ...[i.e.,] a "locally asymmetric domain cosmology (LADC)." Following baryogenesis, the walls of the initially CP symmetric vacuum between the positive and negative CP domains must vanish because they are quite massive and could eventually dominate the evolution of the universe, in conflict with observations."
