If I remember correctly, they are attributing both expansion and contraction to black holes and other things of massive gravity that distort space time. Although black holes absorb matter, they do constantly loose some of their density, when there is nothing left to absorb, they only get smaller in size. This plays into the safety of creating black holes on earth, they would be so small they would instantly disappear. There is some other theory out there that says that when then last black hole ceases to exist, so will the universe. If you look at black holes in the common diagrams, they are marked by severe alterations to space time. See image:

That would act as grounding. Think of it as putting a pin through a sheet of paper on a bulletin board, as the pin is slowly removed, the piece of paper loses its connection to the lower piece. When the grounding ceases to exist (as in there are no more black holes) the universe will simply fall apart. I don't know if I buy into that idea, and it was really confusing to read about and I probably rephrased it wrong, but it is an interesting theory.
Another theory is that eventually one black hole will absorb all the information in this universe. All that information will be ejected into a parallel universe or it will recreate the conditions prior to the big bang. When the ultra black hole no longer can support its own massive gravity, it will explode, similar to the big bang.
Edit: Whoops. Didn't see your last post, Paul. Hehe.
You phrased it correctly, but yeah it is confusing...
I kinda believe the parallel universe theory..

One thing that always intrigued me was the thought of super black holes. Collapsed stars that become so massive that they become black holes (even light cannot escape their pull of gravity), and eventually these get larger and larger as they suck up more and more matter around them, eventually whole solar systems and galaxies.. Perhaps it is one of these that sparks an explosion that is similar to the "Big Bang", but maybe on an individual scale (unless the black hole becomes large enough to suck in the whole universe, and the point of "explosion" just happens to exactly be the size OF the universe's matter combined...)

What do you think is inside of a black hole?
What if it's just a universe transporter, and it's really nothing to be afraid of?

It just sucks in light, and planets and everything and just moves up to a different spot.
Hopefully black holes are friendly, cause I could see something like that happening in the future.
Who cares about the economy if we're gonna get eaten by a super black hole?
I just don't see how an 'explosion' creates matter, or our planets. And then how does life begin? How did we even get that first organism?
It would have had to come from somewhere, maybe it got sucked out of somewhere by a black hole

The theory of a black hole can't be actually proven, as its name describes. Since no light can escape from it, it is invisible to the naked eye. Right now all we know is that we can see the gamma radiation being emitted from them and the fact that there is definitely SOMETHING that has so immense a gravity that it distorts all space around it. However, it is a pretty safe bet that such a thing exists. That, or something very close in nature to what we coin as a black hole.
If it exists, It's not safe

So since we can't we can't see it, there could be an enormous one forming far away in space where we can't detect it?
Is that why space is black? The light is sucked out of it?
