both of the black hole will join together as one big black hole. they can either have a direct hit or both spin, twirling into each other until it create a new super big black hole.
I'm not sure what you mean, but in luminescence, the crab nebula trumps black holes infinitely. However, if the two met, the black hole would still be around the next day.
You would have a black hole the size of the combined mass of the two black holes.
A vacuum and a black hole are two very different things.
If you go into a black hole you will be stretch out into two and then you will be crushed.
The two black holes will merge to form a single, larger black hole with a mass equal to the combined masses of the original two.
When two black holes get close enough together, they might merge, to form a larger black hole.
The two parts of a black hole are the event horizon and the singularity. The event horizon is the "surface" of the black hole, and is imaginary. The event horizon's appearance is caused by the bending of light. The singularity is a point of space where everything that gets sucked in is crushed to about the size of an atom.
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.
No, the two things are quite different.
black and hole are two ask some one else for others
one
Define a "hyper black hole". A "Hyper Black Hole" is a massive "Black hole" thought to be created by many Black holes merging together. Theological Physics now believe that most galaxies, including our own Milky Way, have a "Hyper Black Hole" in the center
