How does a black hole start?
2016-03-16 but recently Stephen Hawking has said he doesn't believe Black Holes exist.
So there are three sizes of stars: small, medium, and large. All stars rely on nuclear fusion. (Please look it up if you don't know what is because I suck at explaining it :P ). Eventually these stars run out of the fuel that they use for nuclear fusion and they've reached the end of their lives. When this happens the large stars become what's called red supergiants. Eventually, since there isn't any more fuel for nuclear fusion to take place, it stops. Now this can go one of two ways for large stars: (note that this next thing DOES NOT happen for small and medium stars.) they can become white dwarfs or black holes depending on their size, and I'm only gonna explain black holes. When the moment comes that nuclear fusion stops, the gravity of the massive star sucks it in to its own core since nuclear fusion is no longer occurring to keep this from happening. What's left is something with so much density that its gravity is inescapable. This is a black hole. Tada.
A star gets ridiculously big and collapses. It collapses with such force, however, that it never stops collapsing. So, therefore, it never gets down to nothing because that makes it not exist at all. But it gets down so small that it goes negative when the sides pass through each other. The time it would appear to take, to an outside observer, would be absolutely no time at all. Inside the hole it would take an infinite amount of time. At this point the star gets negatively bigger, but is a hole in space-time. This means that it doesn't exist, but in a sense it still does because it is existing negatively. This means that if you were to pass into it, you would never get to the other side because you would go to the negative dimension, where you would also exist negatively. After the hole passing through itself, the time it takes, to an outside observer, for the hole to get big enough that it consumes everything would be infinite. The time it would take inside the hole would be absolutely no time at all. Of course, most of what I am saying is just my theorizing, but to me this seems to be ironically the most 'logical' explanation of black holes.
these links should help:
A black hole forms when any object reaches a certain critical density, and its gravity causes it to collapse to an almost infinitely small pinpoint. The particles attract each other so much (as gravitational force is proportional to mass) that the whole thing collapses into itself. Stellar-mass black holes form when a massive star can no longer produce energy in its core. With the radiation from its nuclear reactions to keep the star "puffed up," gravity causes the core to collapse. The star's outer layers may blast away into space, or they may fall into the black hole to make it heavier.
