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. Kip Thorne bigblackcompact Change image and share on social
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. Kip Thorne backwardbuildgeneral share on social
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. Kip Thorne airblackcentral share on social
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. Kip Thorne axisbathtubblack Change image and share on social
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. Kip Thorne detectearthgravitational Change image and share on social
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. Kip Thorne blackcenterfind Change image and share on social
If you have a wormhole, then you can turn them into time machines for going backward in time. Kip Thorne backwardmachinetime Change image and share on social
