- 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*.
