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. When the temperature of the phase transition TPT is higher than 109 GeV, these black holes evaporate until now. If TPT<109 GeV, we may see these black holes in our universe. 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. We can guess the SUSY breaking scale from the mass of the black holes.
