Kip Thorne Quotes
-
Simplicity is the touchstone in finding new physical laws. … If it's elegant, then it's a rough rule of thumb: you're on the right track.
-
I do hope that 'Interstellar' and this kind of science in film will catch the public fancy and help to reignite an interest in science - and a respect for the power of science in dealing with the problems that society has to deal with.
-
We're going to need a definitive quantum theory of gravity, which is part of a grand unified theory - it's the main missing piece.
-
Our universe - it's three-dimensional, but we can pretend it's two-dimensional so it's like this sheet of paper - and we live in Pasadena over here and London is over there, and it's thousands of miles from Pasadena to London.
-
I have used movies to go to sleep at night. You flip from channel to channel to channel and see just enough to make your brain mushy and go to sleep.
-
The right answer is seldom as important as the right question.
-
Each black hole spins on its axis like the Earth spins. That spin creates two vortexes of twisting space, somewhat like vortexes in a bathtub or a whirlpool.
-
As early as I can remember, I wanted to be a snowplow driver. When you grow up in the Rocky Mountains, like I did, you see the snow drifts piled up six feet high, and you're two feet, so it's impressive.
-
We see no objects in our universe that could become wormholes as they age.
-
A big misconception is that a black hole is made of matter that has just been compacted to a very small size. That's not true. A black hole is made from warped space and time.
-
A black hole really is an object with very rich structure, just like Earth has a rich structure of mountains, valleys, oceans, and so forth. Its warped space whirls around the central singularity like air in a tornado.
-
The human race has a yearning to explore. That's part of our biological and psychological makeup.
-
If you have somebody who's brilliant and highly creative with a different point of view than you have, and a very different intellectual background, great things can happen.
-
If you have a wormhole, then you can turn them into time machines for going backward in time.
-
'Closed timelike curve' is the jargon for time travel. It means you go out, come back and meet yourself in the past.
-
Gravitational waves will bring us exquisitely accurate maps of black holes - maps of their space-time. Those maps will make it crystal clear whether or not what were dealing with are black holes as described by general relativity.
-
I became interested in this question of whether you can build wormholes for interstellar travel. I realized that if you had a wormhole, the theory of general relativity by itself would permit you to go backward in time.
-
It was quite a surprise when I realized that with a single wormhole you could have time hook up towards the future or towards the past and that you can actually manipulate the wormhole and change how time hooked up.
-
We have to have a combination of general relativity that describes the warping of space and time, and quantum physics, which describes the uncertainties in that warping and how they change.
-
Whether you can go back in time is held in the grip of the law of quantum gravity. We are several decades away from a definitive understanding, 20 or 30 years, but it could be sooner than that.
-
If you go down through the horizon of a black hole, at the center you don't find a tunnel that leads you to some other place in the universe.
-
When gravitational waves reach the earth, the waves stretch and squeeze space. This is a tiny stretch and squeeze. Far too small to detect with ordinary human senses.
-
Sending people into space is very important culturally. That's really the justification. You cannot rationally justify it on the basis of the science and technology we get out of it.
