No one we know about
No, a black hole is not actually a hole in space. It is a region in space where gravity is so strong that nothing, not even light, can escape from it.
the black hole is a matter in outer space that is made by the force of gravity
Yes, a black hole could travel through space.
The interior space is just black, a black hole is something that light can't escape through and no one has ever been in one, and no one will ever go in one because they are most likely going to get torn up and shredded into molecules. So, the interior space in a black hole is nothing.
Obvisouly it is not a black hole! :)
Yes
no because it would destroy the space if it went in to a black hole
The black hole itself cannot be seen, however, its pulling effects of the surrounding area can be seen.
No non-fictional astronomical body know as black circle. If the question is meant to employ the term 'black hole' in space, what a black hole does is to exist.
Theoretically a rip in the fabric of space
Space doesn't, mass does.
