Actually, miriam, BBT DOESN'T claim there was a central starting point.
Since the universe contains all points, at the moment of the monobloc,
all points were contained within it, there was nothing outside it, see?
I think that this is one of the big conceptual stumbling blocks that the
SST people can't seem to grasp.

The problem is that zero point field energy can only be drawn out into
existence as matter in the presence of an event horizon. Without such a
boundary layer to separate particle pairs, the particle pairs cancel
each other out.

I have never understood why most people have a problem with the idea
that the end of the universe does not have to mean the end of
themselves. As one who has subscribed to an extropian way of thinking
isnce early childhood, the prospect of outliving the universe, and
experiencing infinite others, is infinitely more appealing.

There is, after all, a limit to how much you can know and experience in
this universe, and there is far greater possibility for experience in
traveling to other universes.
