There is no place for God in theories on the creation of the Universe, the physicist and mathematician Professor Stephen Hawking has said.
He had previously argued that belief in a creator was not incompatible with science - but in a new book The Grand Design, he concludes that the Big Bang was an inevitable consequence of the laws of physics.
