Black Holes

Black holes are pretty much a mystery to everyone. Since we've never been out in space, we've never actually been able to study them close up. However, based on observations, some theories have been produced to try to explain them. The most accepted one is that black holes have gravity wells so deep that time is stopped near them. This makes an event horizon that things can go in, but nothing comes out. Once something (such as light) is past the event horizon, it can't get back out. It's also been shown that black holes have a temperature and give off Hawking radiation. This means that a black hole actually can evaporate if it's small enough if it's giving off more radiation than taking in mass. The study of things like this could make space exploration safer when we get more technologically advanced and are able to go that far into space. I wish that in my lifetime I would get to see humankind adventure that far space into space to see what a black hole actually does, but I know that it will most likely not happen for many, many years.
