Re: Never-ending Universe
That's quite an interesting mail. I've got good news for you.
Don't be worried about an ever expanding universe, their are some weird
physical tricks to get around it...
As Freeman Dyson points out in his book "Time without End", it is
possible (at least in principle) for any civilization to survive FOREVER
- even when the rest of the universe is cooling down to absolute zero.
The trick is a kind of hibernation - not just sleep, but complete
suspension of all technical and biological processes - so no energy is
spent, and we wouldn't even recognize it...
If an entire civilization is subjected to an alternating cycle of
awakeness and hibernation (while the hibernation phases get LONGER each
time), it can survive an INFINITE time - whith a FINITE energy reserve.
According to Dyson, this trick would allow our present civilization to
persist ETERNALLY - and it would only need the energy the Sun produces
during EIGHT HOURS!
So it's up to you now to build a global scale refrigerator....
