When Albert Einstein put forward his theory of relativity, the thing that bothered him was that his equations indicated that the universe was expanding, and therefore must have had a beginning. It was not until Edwin Hubble showed that the furthest galaxies were fleeing away from each other that Einstein accepted what we now call the Big Bang theory; that both the Universe and time had a beginning. He became convinced that matter, energy, time and space were created by an intelligence outside of time and space; an intelligence about which he said: ‘Everyone who is seriously involved in the pursuit of science becomes convinced that a spirit is manifest in the laws of the Universe…a spirit vastly superior to that of man, and one in the face of which we with our modest powers must feel humble.’
