Current theory indicates that once matter (or light) crosses the event horizon, it can never leave, since the escape velocity exceeds the speed of light.
This depends on the size of the black hole, and on the density of the surrounding material.
There is no limit to how much a black hole - any black hole - can "swallow". Any matter that gets close enough falls into the black hole, increasing its mass.
heck ya the biggest one is large enough to swallow the one beside it
No. We are at a safe distance from the galaxy's central black hole and there is no reason to believe that will change.
A single one, no, not realistically. A single one, no, not theoretically. Most of what black holes "suck up" isn't really destroyed inside the black hole. It may be spaghettified and then thrown off into the infinite ether of space in a quasar, but no black hole is large enough (or is there a galaxy small enough) for one to destroy (or suck up) a galaxy.
No, the black hole will swallow it because it's gravity is much stronger than the blue giant star.
anything it can reach that cant travel even faster than the speed of light. Absolutly everything.
Yes a black hole could envelope our solar system but it does not swallow anything.
no of course not no of course not
heck ya the biggest one is large enough to swallow the one beside it
No.
A black hole can,but it is very rare for a black hole big enough to swallow Earth.
In general, nothing. Another black hole could swallow a smaller one, if it's small enough it would destroy itself, but anything else would lose to the black hole.
it may expand and swallow and swallow us.
No, a supermassive black hole is what makes a quasar.
Yes, it is possible for a black hole to capture another one and "swallow" it.
No. We are at a safe distance from the galaxy's central black hole and there is no reason to believe that will change.
Nothing, unless a black hole comes very near to us. By the way, you shouldn't say "the" black hole, unless you make it clear which black hole you mean. There are many black holes.
