Yes
Yes, all black holes 'suck stuff up'.
black hole got it's name because when look at a black hole, you only see black. also if you drop an item in the black hole the item is gone because there is a hole in there. so that's how black hole get's its name
it is said that there are black holes in space which we have discovered is true and how gravity realates to a black hole is well, a black hole is said to suck away other universes we have not discovered yet gravity pulls things to the ground and a black hole uses that same pull force to suck in universes
Since whit holes only exist mathematically, a black hole could not pull in a white hole.
They're still called black holes. A black hole remains defined as a black hole as long as it absorb everything near them, both energy and matter, including gas.
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.
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.
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.
A black hole will attract you through its gravity - just like any other object will.
Unlikely. The universe is a very big place, even next to the largest black holes we know. For a black hole to suck in the entire Universe, it would need to be nearly as massive as the universe itself. There is no way that such a black hole could form.
No, black holes are actually invisible because it can suck it Light as well, so no light can escape from the black hole.
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.
