The assumption running through these posts is that an open universe
would tend toward a flat energy gradient -- that "heat death" would be
the outcome. I question this assumption. Again, I offer the work of
David Layzer as a possibility. His model of an open hyperbolic
universe does not allow for heat death.
Anyway, as Anders mentioned, we've a long time, if the universe is
open, to think about it.:)
