That messes up space such that the outward direction is
always downhill, so the universe is literally falling
apart. This might seem a bit too speculative, or even dumb
as hell, but it's a lot shorter than Sarfatti's.....[snip]

Sounds not bad.. but what keeps the bubble from collapsing?

From my point of view, the only answer I can think of is "It
just doesn't." The other possibility is that it is collapsing,
but there's no time out there, nothing really changes-for now.

And do you think the matter beyond the "horizon" returns
into that infinitely dense mass of packed quantum
singularities? C.

Yes! This universe will just end up as a bunch of new
singularities, one for each galaxy. After a certain number of
galaxies take their time with them into the mass, the clock will
start and the bubble will snap shut. Note that I can't prove
any of this.
