So remember to look up at the stars and not down at your feet. Try to make sense of what you see and hold on to that childlike wonder about what makes the universe exist.
Stephen HawkingIt is impossible to imagine a four-dimensional space. I personally find it hard enough to visualize a three-dimensional space!
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.
