Yes, people who get stressed by the expansion of the universe should
learn to relax. But not too much... :-)

Yes, this is an interesting problem. Mitch made a suggestion a month
ago on the transhuman list for a way of creating a closed
mini-universe, but I think it wouldn't work in its proposed form (just
an idea, Mitch: what about a non-spherical geometry?).

I think it sounds reasonable. Divide the universe into two sides, and
use one as an entropy dump. If it gets too "hot", wait for a while
until it has expanded, and then fump more entropy into it. Of course,
I suppose this would run into the NIMBY (Not In My Back Yard) effect
on a cosmic scale.... :-)
