This was an interesting read, but I didn't understand exactly what leads to the big crunch. I get the exclusion principle leads to pressure, and this causes the bounce, but why would it continue to accelerate and then decelerate resulting in a big crunch?

I don't understand where the rest of the parent universe is if all of the matter has emerged from the event horizon. Twisted into a new dimension, perhaps?
My take away was that it's still somehow causally disconnected from our universe. They make an assumption that the space outside is empty and that makes the numbers correspond closely with observations. Maybe there is stuff there but very very far away?
