No. We have never even directly observed a black hole; only the effects of what we think are black holes. The nearest black holes are many light years away, much farther than we have ever been eable to explore. We can only observe through telescopes.
The black hole nearest to our Earth is (fortunately) several thousand light years away. No human has been farther from our Earth than our Moon. Thus, we are technologically quite a ways away from being able to travel to a black hole.
No one has ever visited a black hole.
There already are black holes.
Well, since nobody has ever been in a black hole....... what do you think?
No non-fiction person has ever gone into a black hole.
Should Earth ever collide with a black hole, it would get destroyed.
According to current theory, a black hole, if it exists, begins its life full,and nothing that falls into it ever leaves it.
No,it is impossible
No.

no the galaxy is way to big for a black hole to do much in fact we now know that there is a supermassive black hole in the center of our galaxy right now.
