Megaport writes "Promoting his new series on the Discovery channel, Stephen Hawking has given an interview to the Times in which 'he has suggested that extraterrestrials are almost certain to exist but that instead of seeking them out, humanity should be doing all that it can to avoid any contact.' He says, 'I imagine they might exist in massive ships, having used up all the resources from their home planet. Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach. ... If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn't turn out very well for the Native Americans.' Personally, I've always thought that the indigenous people of the world really had no chance to avoid contact here on such a small planet, but is hiding under our collective bed an option for humanity in the wider galaxy?"
