there is belived to be a black holes but is about billions of miles away, when a star exploxed it could go into a supernova and i am not sure about this but it may turn into a black hole.
it is really your hole the black one it is really your hole the black one
A black hole can't really form inside of another black hole. If you think of a black hole forming after a star goes supernova, then there isn't really a star to go supernove inside of the already created black hole. In fact, there isn't even any space inside of the blak hole for anything to happen. Two black holes can join together, but they wil eventually go to one.
That's not exactly what happens. What really happens is that they just absorb each other and become a bigger black hole.
A black hole relates to physics, because it "bends" the laws of physics. Noone really knows what a black hole does. It bends the law of gravitation (a black hole has way too much gravity).
Not really.
really really dense material that comes from a supernova explosion
Not really, but in a Galaxy next to the milky way there is alot of activity and possibly a black hole.
None, really. At least, for us, and now. A black hole can be dangerous if it's very massive (such as a supermassive black hole). But mainly, a black hole would be completely harmless, unless it gets close - and the nearest known black hole is at a distance of about 3000 light-years. Even a supermassive black hole would be harmless at such a distance.
Well, a singularity is part of a black hole. Although no-one really knows what existed before, a likely explanation is that every black hole contains another universe. So when our black hole was created, we were too.
Astronomers indicate the probability of us all really going to be sucked into a black hole to be quite low.
Yes, a black hole is usually a star that has been compressed to a point where the density is really high.
No really, no. A black hole does that.
