Scientists worry that real aliens might want to kill us

If you're thinking that any aliens we find out there will be more cuddly E.T. than devious V, maybe you should think again. At least if we're to believe Marek Kukula, public astronomer at the Royal Observatory in Greenwich, as reported by The Telegraph.

"We might like to assume that if there is intelligent life out there it is wise and benevolent, but of course we have no evidence for this," said Kukula, who was attending "'The Detection of Extraterrestrial Life and the Consequences for Science and Society," a two-day conference held at the Royal Society in London. "Given the consequences of contact may not be what we initially hoped for, then we need governments and the U.N. to get involved in any discussions."

Considering how well governments have handled first contact with alien life in films and on TV so far—which often turns out to be an exercise in "dissect first, ask questions later"—we're not sure that's such a good idea. But what do you think?
