According to Linde et al, supergravity may cause the dark energy to
become attractive and trigger a very fast collapse in the near
future (just a few tens of billion years! scramble! fasten the
hatches!). Unfortunately for the orthodox tiplerites, this collapse
looks very fast, so it is likely not slow enough to allow infinite
information transmission.

Wild speculation (besides the highly speculative physics here): if
the change of the fields could be made inhomogeneous things might
become *very* interesting - parts of the universe collapsing while
others are still expanding or collapsing at very slow rates. That
would be a shear energy heaven, and maybe one could engineer the
whole thing to be more life-friendly. But we better find a way to do
that engineering soon! :-)
