In theory, yes, if they exist. Unfortunately, you would die in the process. Physics in a black hole are different to the physics we know. First, your body would be sucked in, your body pulled to an infinite length, and your organs and bones would be crushed by the imense gravity. Then, your body (or what's left of it) would be pushed into a singularity, which is about the size of an atom. You would then be dead. Furthermore, whatever you were seeing out of your spaceship/spacesuit would be melted by the heat eminating from the black hole.
So, to answer your question, yes, but I wouldn't try it.
There are already black holes within the universe
If you mean powers like flying and invisibility, that is impossible. The only beliefs of powers like that is if you survive going through a black hole and that is impossible. When you go near a black hole, you stretch like spaghetti and die. Some scientists believe there is a parallel universe on the other side of a black hole. Parallel universes usually are excactly the same but completely opposite. We do not have powers in the real Earth, but in the parallel Earth, powers may be there.So my answer is you can't get powers. You can get magic powers by shaking the hand of a qualified magician.
a black hole sport, a black hole.
Perhaps you are confusing Universe with galaxy. Most galaxies have a black hole in their center. The Universe has no such thing as a center.
No, the universe is mostly a vacuum but a black hole is (theoretically) when gravity goes wild and rips a hole in space and time
Well if it DOES happen and a black hole DOES destroy the Universe, then we won't be around to worry about it.
Unlikely. The universe is a very big place, even next to the largest black holes we know. For a black hole to suck in the entire Universe, it would need to be nearly as massive as the universe itself. There is no way that such a black hole could form.
No. Since the black hole is a part of the universe it would be physically and logically impossible to suck itself into itself.
If you mean the 'other side' of a black hole, we don't really know. The other end of a black hole could be a rabbit hole, spitting matter into a parallel universe. Or perhaps there is no other side and matter is simply gone. Many believe it is possible that black holes could be gates into other universes or parallel worlds. However, since we haven't thrown anyone into black holes, we don't know what lies on the other side.
The universe likely contains millions upon millions of black holes.
It is a possibility that the Universe resulted from a black hole, and that black holes in our own Universe result in new universes. But all this is extremely speculative.
No. If it were, we wouldn't be here, as the atomic structure necessary for life is not possible in a black hole.
