How do black holes “consume” light?
In: 378
Imagine you are driving down a highway. It’s out in the middle of the desert, and the road just stretches on and on, in a straight line, seemingly forever. You drive and drive, and you don’t turn. You’re going in a straight line, right?
Wrong. You are traveling in a curve. The Earth itself is curved. If you were to look at the road from an angle, from outer space, you could see that it was curved. But on the road you don’t notice that it’s curved.
The gravity around a black hole is so strong that *space itself* is curved. It’s curved all the way in a circle. Not a real circle, but like a freaky circle. You can go forever in a straight line and wind up back in the same place. Even light can’t get away, because it is traveling in a *straight line* through *curved space*. A freaky infinite circle.
What’s it like inside? Nobody knows.
