STEPHEN HAWKING IS STILL AFRAID OF ALIENS

Humanity should be wary of seeking out contact with alien civilizations, Stephen
Hawking has warned once again.




In 2010, the famed astrophysicist said that intelligent aliens may be rapacious
marauders, roaming the cosmos in search of resources to plunder and planets to
conquer and colonize. He reiterates that basic concern in "Stephen Hawking's
Favorite Places," a new documentary streaming now on the CuriosityStream video
service.




"One day, we might receive a signal from a planet like this," Hawking says in
the documentary, referring to a potentially habitable alien world known as
Gliese 832c. "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."

For what it's worth, some other astronomers believe Hawking's caution is
unwarranted. Any alien civilization advanced enough to come to Earth would
surely already know of humans' existence via the radio and TV signals that
humanity has been sending out into space since 1900 or so, this line of thinking
goes.

PLAY SOUND



The alien musings are just a small part of "Stephen Hawking's Favorite Places."
The 26-minute documentary shows the scientist zooming through the cosmos on a
souped-up CGI spaceship called the "S.S. Hawking," making five separate stops.




"In 1974, Caltech [the California Institute of Technology] offered me a job in
California," the Englishman Hawking says in the documentary. "I jumped at the
opportunity. In the sun with my young family, it was a world away from the gray
skies of Cambridge, [England]. I've traveled the globe, but I've never found
anywhere quite like this."
