Vacuum Selection by Collapsing

Abstract

In this talk, we discuss the possibility that the vacuum is dynamically determined in the history of the universe. The point is that some of the bubbles with a certain vacuum shrink by the evolution of the universe via gravity and may become black holes. It is interesting that in many cases false vacua are favored in the context of cosmology. By using this argument, supersymmetry(SUSY), if it exists, can be broken cosmologically. This talk is based on Ref.[1].
