For those of you wondering what it would be like inside one of those, it would be nothing, just an endless void of blackness. Now i know the theories about it sort of being a worm hole and taking people back in time or forwards in time. But if that is true, we will never know. You see, what black holes do is not just suck up stuff. A black hole, no matter what size can easily swallow anything it can fit. What a black hole does is takes the star, or planet, and squeezes it till there are nothing but atoms left. So if a human were to go in they would be able to live for a few but the further they get in the black hole the more dangerous it is. You will just reduce to atoms. Now a black holes grip is strong. Once you are stuck in one, or once something is stuck, there is almost no chance of getting out. Black holes are strong enough to devour light, grow, squeeze literal stars and planets to microscopic atoms. That is something to think about.
