If the total energy of the universe must always remain zero, and it costs energy to create a body, how can a whole universe be created from nothing?
Stephen HawkingI believe in the possible. I believe, small though we are, insignificant though we may be, we can reach a full understanding of the universe. You were right when you said you felt small, looking up at all that up there. We are very, very small, but we are profoundly capable of very, very big things.
