Oh dear, now I'm definitely out of my depth.  Omega refers to space-time
curvature, that everything will come back in a Big Crunch, something like
that?  No, no reason at all.  But, hypothetically, is there any reason to
think that those phase changes are irreversible, if the necessary heat
and pressure conditions are established?  I mean, it's not as though we've
actually done the experiment ourselves either way... though I'll concede
that what the cosmogenists are coming up with sounds convincing *to me*.
