Aliens exist but they may be dangerous: Hawking
Aliens may exist but mankind should avoid contact with them as the consequences could be devastating, British scientist Stephen Hawking warned on Sunday. "If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans," the astrophysicist said in a new television series, according to British media reports. The programmes depict an imagined universe featuring alien life forms in huge spaceships on the hunt for resources after draining their own planet dry. "Such advanced aliens would perhaps become nomads, looking to conquer and colonise whatever planets they can reach," Hawking warned. The doomsday scenario is suggested in the series Into the Universe with Stephen Hawking on the Discovery Channel, which began airing in the United States on Sunday. On the probability of alien life existing, he says: "To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.
