A black hole is a condensed piece of matter in which its gravitational force is phenomenal. Once you pass the even horizon, not even the speed of light can save you. But as Isaac newton said, energy cannot be created or destroyed, so black holes shoots energy particles in the form of gamma radiation and other particles into space ofter it devours something huge. It is an endless cycle of life, just hope you don't ever come face to face with one.
Not really.
No you really cant walk inside a black hole, you only float then you die shortly
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.
yes, there is actually a giant black hole in the center of our galaxy, but don't worry because we are safely orbiting around it. A black hole is basically really really really dense material, which forms a blob where the gravitational pull is so stong nothing can escape it, not even light. It can also bend the laws of physics
No. A black hole intakes matter. After it is broken down by gravity. Then it releases it as particles (Neutrinos for example) There is not another universe within a black hole. Nor do stars or matter stay within the black hole. Of course all of this is theory with some really fun math attached to it.
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).

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.

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.
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.
