A black hole is the result of the gravitational collapse of a massive star. This happens when the star runs out of fuel.
Only around a black hole. There is a sphere around every black hole where light orbits the black hole.
We know nothing about the conditions within a black hole, but it seems unlikely that a black hole could exist within a black hole, or even if this concept would have any meaning at all.
Nothing, unless a black hole comes very near to us. By the way, you shouldn't say "the" black hole, unless you make it clear which black hole you mean. There are many black holes.
no you can not
no black holes are stars
A black hole needs to be a minimum of about 3 or 4 solar masses.
you lure the sharks toward you, fly to the black hole, and the sharks get sucked in the black hole
It takes a dying star 20 times the size of our sun to create a black hole. So no they can't.
Space doesn't, mass does.
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

A black hole originated as a star, that is, the star converted to a black hole.
Since the nearest black hole is many light years away from Earth, it's impossible for a scientist to physically travel to a black hole to study it. Instead, they have to make do with observing the effects of black holes from Earth.
