The stuff it takes in stays in the black hole, making it bigger (i.e., more massive), and thus more powerful.
Uh...the obvious. They produce and reflect no light at all (black) and stuff goes in it (hole.)
A black hole isn't a tunnel to somewhere else. It just does to the center of the black hole, and is crushed into a little speck.
Yes, all black holes 'suck stuff up'.
Its mass. All the stuff it has swallowed.
The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.
It is believed that all galaxies have a black hole at their centers.
Its called a Super Black-hole and scientists believe it is what holds all galaxies together.
there could be a whole new universe or just takes you into a different place in space or they don't end at all
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.
It is a hole because it brings things inside of it, but it's all black so you can't see anything.
A black hole sucks all the mass and energy which passes it, even light. So it's called black hole.
