it's called "time dilation" if you look into relativity, Einstein describes the constant of the universe being the speed of light. Since a black hole is infinte in gravity, the black hole sucks in the light. So it in a since changes the constant that constrains time and so to speak "eat's time!"
Don't know which black hole.
yes. but the intense gravity is so strong it seems to bend time so slowly some people believe that there is no time in a black hole I WOULD JUST LIKE TO POINT OUT that time does exist in a black hole it is just extremely slow on another note if time did not exist in a black hole then a black hole would not suck things into it. so time does exist in a black hole.
yes it can eat ANYTHING in space.
They just sit - and "eat" anything that comes too close.
Scientists cannot be certain, as we have yet to experiment with a black hole, but they theorize that time would slow down relative to time far from the black hole.
Yes. In the neighborhood of a black hole, both time and space are distorted, due to the black hole's strong gravitational attraction.
First, it isn't the "weight", but the mass of the black hole that is relevant. Second, the black hole does, indeed, greatly distort space and time in its neighborhood.
Yes the black hole can be destroyed. However, man-made objects cannot resist the gravity without getting sucked in. The only thing that can destroy a black hole is time in a process called Hawking Radiation in which the black hole evaporates over time. The smaller the black hole, the faster the process.
Gravity is stronger in a black hole, if that's what you mean. It's in a black hole that space and time are distorted to such an extent that not even light can escape.
If you mean strike as is first "eat" a star, than this happens as soon as the black hole is created. The black hole will eat its own nova (gas and dust) when it implodes and if it has a star close to it such as a binary system, the black hole shreds the star apart. This will happen over millions of years since black holes distort time and space around them. Black holes can only "suck" in object that are very close or or objects that get close to them. For example if our sun were to become a black hole (which it wont) it could only "suck" in stuff that were in a three kilometer radius. So all the planets would orbit normally like they are now.
This is because the gravitational force of a black hole is so strong that it literally warps the fabric of space and time around it.
No, the universe is mostly a vacuum but a black hole is (theoretically) when gravity goes wild and rips a hole in space and time
