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.”
Through March 27, you can also stream, for free, a 90-minute biography of Stephen Hawking on PBS. Hawking, which first aired in 2014, is described as “the intimate and revealing story of Stephen Hawking’s life. Told for the first time in Hawking’s own words and with unique access to his home and public life, this is a personal journey through Hawking’s world.”
PBS is also offering a free stream of Genius by Stephen Hawking. In the six-part 2016 series, Hawking “challenges a selection of volunteers to think like the greatest geniuses in history and solve some of humanity’s most enduring questions. ”
Speaking of time travel …
Narrated by Sigourney Weaver, the film features 100 visionary experts who “collectively dream” about the future in a wide range of categories. Those categories are:
Episode 1 – Cities
Episode 2 – Homes
Episode 3 – Transportation
Episode 4 – Waste
Episode 5 – Food
Episode 6 – Sport
Episode 7 – Entertainment
Episode 8 – Cooking
Episode 9 – Work
