Best Answer

A black hole is called a black hole because due to its density and therefore intense gravity, nothing, not even light, can escape it. Though it has extreme mass, it is not a light source, and it will not reflect any light, so it appears as a "black hole" in the universe.

As a black hole has massive gravity, light from objects behind it will "bend" around the black hole and an observer will see what is called gravitational lensing. The effect of the lensing will be greatly pronounced because a black hole deforms space-time dramatically. A black hole is a point in space where something is, but because the "thing" that is there generates extreme gravity, it will not be visible under any conditions. It was natural to apply the term black hole to this phenomenon.
Because, the huge gravitational forces inside the black hole ensure nothing - not even light - can escape.

Can any black hole turn into a neutron star?

No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.


Can you make a black hole inside a 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.


Is an Intermediate-mass black hole a type of black hole?

Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.
