Re: Tipler's universal resurrection


If you believe in the concept of "uploading" minds
(which I don't), then Tipler's closed universe
endstate may be feasible. Most recent observation
point to an open universe. Dyson has postulated life
of some sort may be able to survive indefinitely via
harnessing vacuum quantum fluctuations.
Another one of Tipler's postulations may hold the key
to immortality: A Time Machine. MNT replicator probes
may one day be able to transform a galaxy sized object
into a massive Time Machine. A viable suspension
technology would be a trivial feat, given the
resources of a Time Machine's own future light-cone.

I'm pessimistic quantum computers will get past about
150 q-bits any time soon (decoherence may not be
avoidable beyond a certain quatum computer size). If
you believe in uploading, a large enough quantum
computer would work. Probably this would require an
even more powerful class of technologies than what is
presently known as nanotechnology.

Could Nanotechnology be used to create some kind of
quantum computer
that would produce the same results?
