<DIV>Hi Russell,</DIV> <DIV> </DIV> <DIV>You might be correct. But are you absolutely certain it's impossible? I recall reading a paper by Nick Bostrom et al. that was concerned that it was *possible* (although not easily achieved) even in light of the evidence of its difficulty - from cosmic rays.</DIV> <DIV> </DIV> <DIV>There are probably other potential existential risks that haven't even yet occurred to any human minds, that a post-human might easily be able to arrange. Eg. Time travel into the very distant past - I agree that it's still speculative at this time. </DIV> <DIV> </DIV> <DIV>Best Wishes,</DIV> <DIV> </DIV> <DIV>Jeffrey Herrlich <BR><BR><B><I>Russell Wallace <russell.wallace@gmail.com></I></B> wrote:</DIV> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">On 5/26/06, <B class=gmail_sendername>A B</B> <<A

If the Universe turns out to be finite, the Bubble would eventually consume all of it, rendering this Universe lifeless and matter-less as well.
