Stephen Hawkings, aged 74, the world-renowned British cosmologist and theoretical physicist, wants to find aliens before they find us.

Hawkings has been sounding alarm and warning us that having aliens visiting us is not necessarily a good idea for our survival, especially alien civilizations that have more sophisticated technologies at their disposal.

In his new half-hour program “Stephen Hawking’s Favorite Places” on science-themed subscription service CuriosityStream, the world’s most famous theoretical physicist flies by the potentially habitable exoplanet Gliese 832c in a CGI spaceship as part of his hypothetical dream itinerary for a tour of the universe.

“If intelligent life has evolved (on Gliese 832c), we should be able to hear it,” he says while hovering over the exoplanet in the animated “U.S.S. Hawking.” “One day we might receive a signal from a planet like this, but we should be wary of answering back. Meeting an advanced civilization could be like Native Americans encountering Columbus. That didn’t turn out so well.
