Sorry for the recent hiatus from the blogosphere, but I was in the process of switching coasts.
Maybe I should have been changing more than that, if what Stephen Hawking recently said is correct. Looking to start a colony on a different planet?
In a new series about the Universe on the Discovery Channel, Hawking said humans should fear a potential alien encounter, and he believes that their existence is virtually guaranteed.
[Hawking] suggests that aliens might simply raid Earth for its resources and then move on: "We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet. 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 colonise whatever planets they can reach."
He concludes that trying to make contact with alien races is "a little too risky". He said: "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."
