Anything that falls into a black hole becomes part of that black hole's mass, which makes the gravity stronger and causes the event horizon to grow larger.
Well first of all white holes aren't proven to exist yet so nobody knows if they pose a threat at all. Unlike black holes, white holes repel everything and spit stuff back into space, so they wouldn't really pose a threat unless they spat out a large amount of mass right at the earth.
Black holes, super novas, and lots of other stuff
No, it just keeps growing as more stuff falls in.
No one knows. Most black holes are assumed to not have or be part of a wormhole (hole in space from one side of the universe to another) - most will just crush anything to infinitely small parts.
There isn't an exact opposite of a black hole in terms of cosmic phenomena. Some theories suggest the existence of "white holes," which are hypothetical regions of spacetime where matter and energy are ejected instead of being pulled in, mirroring the behavior of black holes. However, white holes are purely theoretical and have not been observed or confirmed.
Yes, all black holes 'suck stuff up'.

Stars, nebula, black holes... stuff like that is WAY out there.
Since nothing, not even light, can escape black holes, they are invisible (so to speak). You can only see a black hole when it is sucking up light, since the object with light looks like something is pulling it away.Actually, there isn't much imagination in this. Black holes are named as such because they are, basically, holes in the universe which emit no light.
You can find Planets, Billions of Stars, and Comets, meteoroids, comets, black holes and alot of other stuff.
yes, there are the nebulae, black holes, and planets, but mostly the space in between the stars is nothingness
Yes, just like the Sun, the Earth or the Moon "suck stuff up". Though I would prefer a different term, for example "attracts objects gravitationally".
The reason that a black hole does this is because of its immense gravitational pull. It is so immense that nothing, not even light can escape. Therefore, anything that gets too close to a black hole would be sucked in. Yes, it does. Black holes come in various sizes. It is currently believed that most if not all galaxies have super-massive black holes at their centers. Sometimes these massive black holes will be in a very active state, literally consuming whole stars at a time.

For black holes that last more tham a second, It forever becomes part of the black hole. The short lived ones smash everything to energy then bleed off that energy as Hawking radiation.
