 * I chose to do my wikispace on something that is very unknown. [|Black holes], they are the scariest thing out in space, anything even close to it gets sucked in never to return. Nothing has ever been sent into a black hole so we dont know what happens in there. But one thing we do know, it cant be good.**


 * A black hole is a concentration of unblievable mass, with a [|gravitational pull] beyond that of the suns. That is what prevents things from escaping it, except for space tunneling activity. Or in simple terms, getting sucked around through it until you come out the other end. This means that nothing can escape not even light, thus the name "Black" hole.

To explain to you how the black hole works, it is like throwing a tennis ball. Imagine it, the harder you throw the ball the higher it goes and the longer it takes for it to get pulled back by the earths gravitational pull. But if you can throw it hard enough, it will escape the earths pull, and never stop going until it hits something. They call that an** [|**escape velocity**]//,// **an escape velocity just means how fast something needs to go to escape gravity. The earths escape velocity is about seven miles per second. Right now light is the fastes moving thing ever, nothing can travel faster. And black holes have such a high escape velocity that light cant even escape, so you can see how hard it would be for nything to get out.

My theory on black holes is that whatever goes in gets stuck inside with everything else that has been sucked in and gets stuck together. Some people think that black holes have another side, and that anything that goes in, comes out the other side. But this is impossible, since it has such a high escape velocity nothing would be able to get out the other side. Since light can't even escape a black hole, then the object would have to be going faster then the speed of light to escape the gravitational pull. And if it comes out the other end of a black hole, wouldnt we have seen this other end? Well we havent so there goes that proof. Other people think that whatever goes in a black hole gets crushed down into nothingness. But what causes it to get crushed? Nothing in a black hole could crush it. They are just huge balls of matter, with gravitational pull. Gravity can crush something, but it could stretch something. That is what I think would happen. Imagine going into a black hole feet first, your feet would be closest to the unbelievable gravitational pull so your feet would be getting pulled harder. So your body would be getting slightly stretched. I think that once you were inside the black hole, everything else that was in there would be stuck together and you would be sucked into them, because that is where the source of the black holes gravity would be. Then everything that went in the black hole would just keep making a bigger ball of space junk.
