X-Message-Number: 21384 Date: Mon, 10 Mar 2003 23:50:09 -0000 Subject: Infinite life may be possible From: <> Very interesting article I found on the Extropians list: Indefinite Information Processing in Ever-expanding Universes http://arxiv.org/abs/gr-qc/0302076 Authors: John D. Barrow, Sigbjorn Hervik Comments: 6 pages We show that generic anisotropic universes arbitrarily close to the open Friedmann universe allow information processing to continue into the infinite future if there is no cosmological constant or stable gravitationally repulsive stress, and the spatial topology is non-compact. An infinite amount of information can be processed by ``civilisations'' who harness the temperature gradients created by gravitational tidal energy. These gradients are driven by the gravitational waves that sustain the expansion shear and three-curvature anisotropy. //////// I have always tried to take the perspective, when explaining cryonics, that we should simply assume that the universe will somewho allow us infinite life. The above paper would seem to provide more ammunition for my viewpoint. Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=21384
