Hawking has depicted what kinds of alien could be out there
The scientist, who is paralyzed by motor neuron disease, warned today that contact with alien life could spell disaster for the human race. He says there must be ETs out there and that humanity should do everything to AVOID them!
"The real challenge is to work out what aliens might actually be like."
Professor Cox added:
"Closer to home, the evidence that life could exist on Mars is growing."
