OK - Odd thread. Sorry about this and please move to GD if more suited... I think Stephen Hawking's essay on life in the universe hit me quite hard after his death: http://www.hawking.org.uk/life-in-the-universe.html What worries me is that even if we were to advance to a stage where we can harness the power of our own star (a tier 2 civilisation on the Kardashev Scale) then what is the point of it all? Are we suddenly going to improve the universe somewhow and to what end? Even now our very existence just seems like some cruel practical joke IMO. The whole thing just seems like a massive troll IMO. I suppose that given the pretty smart demographic here, I'm just looking for other peoples' outlook on the whole thing rather than the usual cheesy gutter discussion.
