Yes , they are created when a star implodes (opposite of Explodes) .And has a gravitational force strong enough to curve a beam of light into it.

Some also believe that black holes are at the center of every galaxy including our own and they have been inderectly observed as well. Also know as a singularity, their gravitational pull is so vast that not even light can excape...hence the term 'black hole'.

They were first inferred when astrologists noticed stars near the centers of galaxies rotating around a center at much higher speeds than should have been possible without something with the gravitational force as a black hole.

Does a galaxy contain black holes?

Not really "a" black hole - many black holes. It is currently believed that all, or most, galaxies have a huge black hole at its center. Any galaxy should also have lots of smaller black holes - so-called "stellar" black holes, because they have approximately the mass of a star (larger stars can become black holes).

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.

What happens when a black hole forms in a black hole?

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, black holes are actually invisible because it can suck it Light as well, so no light can escape from the black hole.
