Black holes are huge peices of matter in space that are one of the biggest mysteries of the [|universe]. They are so mysterious because no [|astronomer] or anybody can find a whole lot about them. They have so much [|gravity] from their absolutly enormus amount of mass and weight that they bring everything into them, even light. To give an example, black holes can have 10-15 times more weight than our sun but arent even bigger than Earth, wow! Since light can't even escape them, (even thought light travells at 186 thousand miles a second) thats the reason why black holes are black. If we could see inside them, then we would probably know more about them. Not knowing anything about this pitch black vacuum, what do you think would happen if someone or something went into one?

Thats another huge mystery of black holes; what happens to someone or anything when they get sucked in? Some [|thoeries] of this are: that it is a [|wormhole] to another black hole or place in space, that you can live inside of it, or that you would instantly be crushed and die. Keep in mind these are just thoeries, but the one that I believe is true, that you would be crushed. Black holes have so much compacted into them. They have so much weight and gravity that would be coming down on a persons body. Its hard to say exactly how much weight a black hole actually has, but as I mentioned before, its 10-15 times more than the suns. I'm 100% sure with that amazing amout of wieght on your body that would would instantly be crushed. Comparing this to the wormhole thoery; whatever goes into the holes would have to come out somewhere, which no astronomer has ever seen. Also when something goes into a black hole its mass adds to the hole, which couldn't mean that its a wormhole since the mass wouldn't stay with the black hole then. I deffenitly think its a bad thing to send somebody into one because I do belive that they will get crushed and die. Thats a really unknown thing about black holes, but how are they created and any other cool facts?

Black holes are fromed when neutron stars collapse. When those stars get too big, they collapse and over time it turns into a black hole. The black hole gains mass by taking in anything that comes near it which is mostly dust and gas in space. They are slowly [|evaporating], returning their enegy to the universe. Nobody knows exactly how long that takes but we know it takes a long, long time. In most pictures, black holes appear differnt colours, but they actually are just black. An [|accretion disk] forms around them when gas falls towards it. It is a rapidly rotating disk of gas around the black hole. The gas heats up to millions of degrees because of all the [|friction]; this makes a different colour around the hole. If two black holes colided, what do you think would happen? The only thing is that they become one big black hole. Astronomers have already proved that. The black hole got its name in 1967 by John Archibald Wheeler. A mystery of the universe, but a very awesome and debatable topic, black holes.
