Extraterrestrials are out there for sure, Hawking says, but he added that it is “probably in our best interests to avoid any contact rather than seeking them out.” In a recently released documentary series, he reveals his latest thinking on some of the universe’s greatest mysteries.
In the new series aired on the Discovery Channel, Stephen Hawking made the following conclusion:
“A few life forms could be intelligent and pose a threat. Contact with such a species could be devastating for humanity, with aliens raiding our planet for resources and then moving on.”
He goes on to say:
“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,” Hawking says. “Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach.”
“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,” he concluded.
Recently, another popular astronomer, Lord Rees, issued the following warning about alien life for humanity in a lecture.
“I suspect there could be life and intelligence out there in forms we can’t conceive,” he said. “Just as a chimpanzee can’t understand quantum theory, it could be there are aspects of reality that are beyond the capacity of our own brains.”
