Black holes



So I was doing some research and I found a little knowledge about black holes. So basically everything in the world has something known as a Schwarzschild radius, if you we're to collapse anything into a tiny, tiny amount of space, it's density would be so large that it's gravitational pull would be so large that not even light can escape. Therefore, a black hole. If you compressed the entire Earth into the size of a peanut, it would create a black hole. So let's say that your friend was going to fall into one and you were watching. What would it look like? So as he approaches the black hole, the point when he enters the black hole, since there is no light in the hole, his body literally disappears. The light left before he disappears will turn a red shift and then disappear. That's all for today on black holes. I think we'll come to that topic again soon
