Yes that is what I am refering to.

Yes many "universes" could have been created. All this means is that
there is a non-zero number of "inflationary" universes. This would be
supported, I believe, in the current model.

It may be that the reason that time is special has to do with the fact
that we are being dragged towards the "big crunch" . If you went inside
the event horizon of a black whole things would be different. Inside a
black whole (simple ones) you have no choice but to smack into the
singularity, but you are free to move back and forth in time. If we
currently are inside a black hole we are being dragged towards the
singularity in the future.

"What good is memory if you cant remember the future?" There is still a
little debate on the arrow of time issue. We know it exists; its just
hard to explain exactly why.

The odds of something like a universe popping up would be very-very low.
If we wait around long enough it may happen but dont bet on it any time soon.
