Edward P. Tryon is an American scientist and a professor of physics at Hunter College in Manhattan. Tryon's specialization is in theoretical quark models, theoretical general relativity, and cosmology. In 1973, he proposed that the universe is a large-scale quantum fluctuation in vacuum energy. This is called vacuum genesis or the zero-energy universe hypothesis. He has been quoted as saying, "the universe is simply one of those things that happens from time to time."[1]
