  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].
