To begin with, I'm not an astronomy major, and I know there are many other factors I should take into account when asking these general questions...
Does a star's life end at the stage of a blackhole instead of recycling itself to become a new star? Would the universe eventually run out of matter?
If the number of blackholes only increase, what theories have been proposed to predict what would happen? Is that a reason for the theory of a Big Crunch of the universe?
THANKS :)

Dr M, could you please elaborate?

Sorry, "not run out of matter", I meant if the life of a star ends at the blackhole, there'll be less matter for creation.

I'm not sure if I understand this correctly, but since a blackhole is believed to hold a galaxy together, would they eventually hold and decrease the size of the universe?

Not All stars end up as black holes. ( read more about this)
Universe will not run out of matter. Stars do burn hydrogen and in the process produce helium.
Universe may run out of fuel. Then some other form of stars has to be born or will end up cold and quiet
The theory of big crunch has nothing to do with black holes.
Big crunch is about expansion of universe. Since the universe expands some think that this expansion is not indefinite. Eventually it will collapse. That is big crunch.
I think reading will help you understand more

Do you belive in UFO'S then how do they travel such distants.
A black hole is a tear in space TIME AND SPACE are then meanless. A project which is some 200 to 300 years away would be to set up a mini black hole 1 light year from the sun in order to travel at light speed to the stars but at the moment this is impossible as the space ship would be chushed to bits. but sciences think a black hole is a gate way to other universe a universe oppersite to this one.

The problem with your question is that due to the extreme density inside a black hole, relativistic effects are so pronounced that time stops - so it's pretty hard to imagine anything happening there at all. I believe the latest theories suggest that black holes slowly "evaporate" - meaning that the matter inside them is lost to this universe
