Sounds not bad.. but what keeps the bubble from

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.

You should develop that idea a little further ... How about
space being a form of likewise infinitely dense mass of
packed quantum singularities? With just some inverse
quality .. ? C.

Now that you mention it, I think someone proposed something like
that about 30 years ago. Unfortunately, the place where I read
that was in a book published by Maharishi International
University. It was the "meditators'" explanation for the
existence of everything. I don't remember much of what they
said, but since they're into "transcendental meditation," I know
it was just verbal manure. Here's my own response to your
suggestion.

The universe bubble is actually filled with an incompressible
exotic substance called Singularium, whose density just barely
exceeds that of an elementary particle. (The incompressibility
explains why the bubble doesn't collapse.) Given that density,
the Singularium pressure at the center of the universe is nearly
infinite. All the matter is just contamination. Since the
density of a galaxy is far less than that of the Singularium,
it's subject to enormous buoyant forces. As it rises toward the
outside, it behaves like a bubble rising from the bottom of a
glass of champagne. It expands in the decreasing pressure,
displacing more Singularium and therefore accelerating. I'm not
sure why the galaxy behaves as a single entity rather than just
a bunch of stars, but it clearly does, else this whole idea
would be nonsense.

That settles the accelerating universe question again.
