Perhaps this is a completely different topic but maybe
it's related somehow to whether or not the Universe
is open or closed. I believe that the current
thinking is
that there's only about 10% of the matter that it
requires for the Universe to be closed... so if these
two ideas are related, then perhaps the Universe is
not a black hole.

Frankly, I never really understood the fourth dimension
into which the Universe is curved because of the mass
it contains. I'm guessing it's the time dimension,
but it's never been clear to me what that would mean
for it to be closed...except that at some point the
Universe would again collapse (maybe?)

It's easy to picture it as a
spatial dimension, but time... *shrug* too weird.
