Stephen Hawking: Don't talk to the aliens!
But according to Stephen Hawking, we should stop looking and start hiding.
His brainiac ability tells him that yes, there is probably life out there.
"To my mathematical brain, the numbers alone make thinking about aliens perfectly rational," he says on his new "Into the Universe with Stephen Hawking" show on Discovery Channel. "The real challenge is to work out what aliens might actually be like."
He believes most of it will be like the microbes and simple celled animals that has dominated Earth for most of its history.
