What discovery by Edwin Hubble led to the development of the Big Bang Theory?. The Universe. The big bang theory. Happened approximately 13.5 billion years ago. The Big Bang was caused by the density of the compressed galaxies. It was in a very high density state, then it expanded. After the beginning expansion, it cool to let subatomic particles and later on, simple atoms to form. .
