Hawking and Time Travel

Physicist and cosmologist Stephen Hawking, who passed away this week at 76, not only pushed the boundaries of scientific understanding; he made mind-bending concepts accessible to a curious public.

One such concept was time travel.

Last fall in Cambridge, StarTalk host and Hayden Planetarium director Neil deGrasse Tyson interviewed Hawking about the possibility of time travel, and whether humanity, due to a catastrophe of its own creation, will have to look for a new home elsewhere in the cosmos.

National Geographic has made that interview available to stream free on its website and other platforms.  You can also watch it right here:

During the episode, Tyson and his in-studio guests also try to explain Hawking’s “no boundary” condition. And there’s a review of Hawking’s animated and live-action appearances on such popular shows as The Simpsons, Futurama and The Big Bang Theory.

“His passing has left an intellectual vacuum in his wake,” wrote Tyson on Twitter. “But it’s not empty. Think of it as a kind of vacuum energy permeating the fabric of spacetime that defies measure.”
