For larger objects, this is unlikely to be a problem unless we are talking about billions of years (but I switched out of physics after a year ; -). Cosmic rays and natural background radiation damage is much more of a problem and that only becomes a problem when we get to a hundred thousand years or so. > > My guess for what it's worth is that if cryonics fails, it won't be > for > medical or scientific reasons, but social or political ones.

I don't think patients can be secure, unless there are facilities in at least two countries. That would at least give the option of moving on short notice. Unfortunately, I have yet to find financial support for doing anything along these lines. dss David Stodolsky Skype: davidstodolsky Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=29817
