There are hypotheses about so called 'virtual particles' that may travel faster than speed of light, and hence are not sucked up by Black Holes. Also, Black Holes cannot suck another bigger Black Hole, when they meet a bigger one, they get sucked up rather.
Black holes have such strong gravitational pull that they can theoretically pull in anything that gets too close, including people and rocket ships. However, the likelihood of a person or a rocket ship getting close enough to be pulled into a black hole is extremely low, as we are very far away from any known black holes.
White holes are theoretical regions of spacetime that expel matter and energy outward, the opposite of black holes which pull matter in. They do not suck up objects like black holes do. However, there is no observational evidence for the existence of white holes in the universe.
You can't because they suck in light, there for you cannot see them
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.
Even though black holes suck through parts of the universe, the universe is inevitably big, and growing so as the universe is being sucked into another dimension by black holes, it is also expanding.
Absolutely anything and everything. They may even suck up time(!!!!!), but no one knows for sure.
I think they are black because I saw a nonfiction movie about black holes and the pix from a sattelite showed them black. they either have no color or we can't see what color it is, because black holes suck in light, and anything else within a certain distance. a black hole is formed when a star combusts and its gravity absorbs itself and anything else.
Black holes. They can be so large that they can suck up universes at a time

yes
Anything - whether it be gas, liquid, solid, light, etc. - can be pulled into a black hole if it gets too close.
Yes. The gravitational "Pull" of a black hole is so intense that EM radiation is pulled into it, and even time is warped. However, black holes do not "suck in" anything. A black hole is a region of space toward which things are forced. So light is actually pushed, rather than pulled, toward a black hole.
Yes, all black holes 'suck stuff up'.
Yes
yes but not likely
Yes.
Black holes don't in fact 'suck in' anything; I know you are using the word as a figure of speech. The gravity of a black hole is so strong that if an electric current, or something conducting an electric current, goes below the event horizon, the electricity will not escape. There is some evidence suggesting that black holes do decay over vast time periods. Currently, even the absorption of the background radiation is more than enough to compensate for any decay that is happening in most large black holes.
