Planet Earth is the only one we know of that can support life. We know that it has been around for approximately 4.5 billion years. And we know that it will continue to exist (if we don’t cause irreparable damage to it by our actions, a possibility that is becoming more and more real everyday) for another 5 billion years until the sun swells into a red giant star. Of course these possibilities are very much in the future, we don’t know if we will exist at that time (or we may have evolved into some form of less savoury organism, much like the super slugs portrayed in Star trek : Voyager).
I was re watching ‘The Hitchhiker’s guide to the Galaxy’ for the umpteenth time the other day. Which led me to wonder, again, for the umpteenth time, if there is something, anything at all, that we can do if we are actually faced with possibility of the demolition of our planet. The answer, of course, is nothing. We are not sufficiently technologically advanced to have seen the demolition plans which have been posted in Alpha Centauri for 50 years and there is no way in hell we can relocate almost 7 billion people to another planet outside our solar system (we don’t even know our own system that well, but as far as we know nothing in here can support life as of yet). So in the face of overwhelming odds, I’m forced to say,’we’re screwed’ if that happens.
P.S : Also, there’s absolutely no point to this post, I’m just bored !
