Futurologists (or any forecasters in the social or natural sciences) will tell you
that prediction/forecasting beyond 20 years is folly. I think this is sort of
like the extropian idea of the Singularity. Brilliant people like Stephen Hawking
does talk about "Baby Universes" that could be pinched off from our own (possibly
from wormholes) and the possibility of traveling to a prior point in time within
this universe is also plausible. These notions are more likely to me than saving
a part of the current cosmos we live in per se. Sincerely, Bill
