>but that may be corrected in a few generations. Or not, as the case may be. That's why you send out many such probes. You would have to assume that most attempts would fail. You are, after all, attempting to transplant human life with no human oversight. Either way, it's merely prolonging the inevitable. The Sun has about 5 billion years of fuel left, which is coincidentally about the time the Milky Way will collide with Andromeda, ruining everyone's day. The Sun would be far too hot to support life on Earth long before that, but let's assume we've moved to a more gentrified suburb. Even were humanity to somehow escape the Milky Way in the next 5 billion years, we'll still just be building sandcastle walls in an attempt to hold back the tide. I'm reminded here of Asimov's The Last Question, an excellent short story: http://www.multivax.com/last_question.html http://www.multivax.com/last_question.html
