Can someone briefly explain what Stephen Hawking meant about there being no creator? I have no real views on religion - it doesn't really affect me, but he is quoted in the times as saying 'as long as there is such a law as gravity, the universe can and will create itself from nothing.' Sorry if that's not quite word for word I'm remembering a 2 day old article haha.
Anyway the thing I don't get is before the universe there would be no 'law such as gravity' because there would be nothing, and so surely the universe could not create itself according to his reasoning? What am I missing here? Someone must know physics well enough - I've already tried all my friends!
