Everyone knows that BLACK HOLES suck up everything around them, even light can't escape.
Consider a black hole. It keeps on sucking up the space around it endlessly,
Since there is no limit, infinite amount of space and time are twisted and sucked up,
THERE MUST BE ANOTHER UNIVERSE WITHIN THAT BLACK HOLE!!
IS THAT POSSIBLE? Please Explain.
Waiting for ur kind response.... :confused:

No they don't. Black holes are not vacuum cleaners. The gravity of a black hole depends on it's mass in exactly the same way as that of a star. The difference is that a black hole is smaller than it's own event horizon and if something finds itself inside the horizon then it can never get out. A star is not small enough for this. As far as an observer outside the horizon is concerned a black hole behaves just like any other massive object.
even light can't escape.
If you are outside the horizon and shine a light away from the black hole then it certainly can escape.

Black holes do not "suck up space" any more than they suck up anything (see above). Matter may fall into the black hole and increase it's mass but space is not dynamical in that sense.
If our sun could turn into a black hole (too small), it is said it would not affect the rotation of the Earth around it, since it still has only the same gravity.
Escape velocity is faster than light so light cannot escape it. But only inside the event horizon around the black hole.
Space is literally nothing and only defined by what is occupying it or travelling through it, so not affected by a black hole. Time is just a man made measurement of change.
What is inside a black hole is the material from the original star plus anything sucked into it. The largest black hole found so far is 18,000,000,000 solar masses but even that is far, far too small to permit even atoms to exist inside it.
