“In the early universe—when the universe was small enough to be governed by both general relativity and quantum theory—there were effectively four dimensions of space and none of time. That means that when we speak of the “beginning” of the universe, we are skirting the subtle issue that as we look backward toward the very early universe, time as we know it does not exist! We must accept that our usual ideas of space and time do not apply to the very early universe. That is beyond our experience, but not beyond our imagination, or our mathematics.”
― Stephen Hawking, The Grand Design

“The idea of 10 dimensions might sound exciting, but they would cause real problems if you forget where you parked your car.”
― Stephen Hawking, The Grand Design

“Simplicity is a matter of taste”
― Stephen Hawking, The Grand Design

“It is hard to imagine how free will can operate if our behavior is determined by physical law, so it seems that we are no more than biological machines and that free will is just an illusion.”
― Stephen Hawking, The Grand Design
