“The cyclic universe theory predicts no gravitational waves from the ea...” — Stephen Hawking Quote

“The cyclic universe theory predicts no gravitational waves from the early universe.”

“Only black holes of very low mass would emit a significant amount of radiation.”

“The people who actually make the advances in theoretical physics don't think in these categories that the philosophers and the historians of science subsequently invent for them”

“Wormholes are a gravitational phenomena. Or imaginary gravitational phenomena, as the case may be.”

“Why do guests always end up in the kitchen at parties? Is it a social phenomenon? Some strange gravitational pull? I don't know, but one thing is for sure: If your friends are going to congregate in your kitchen, you'd better make it as nice as possible.”

“I said, suppose you take a light - I was thinking of just light bulbs because, in those days, lasers were not yet really there - and sent a light pulse between two masses. Then you do the same when there's a gravitational wave. Lo and behold, you see that the time it takes light to go from one mass to the other changes because of the wave.”
