The theory of wormholes and multiverse suggests that the parameters of the Standard Model are fixed in such a way that the total entropy at the late stage of the universe is maximized, which we call the maximum entropy principle. In this talk, We show that Higgs vacuum expectation value is determined in order to satisfy maximum entropy principle. We assume that the baryon number is produced by the sphaleron process, and that the current quark masses, the gauge couplings and the Higgs self coupling are fixed when we vary Higgs vacuum expectation value. It turns out that the existence of the atomic nuclei plays a crucial role to maximize the entropy.
