4 May 2017 (USA Today) – It’s no secret that physicist Stephen Hawking thinks humans are running out of time on planet Earth. In a new BBC documentary, Hawking will test his theory that humankind must colonize another planet or perish in the next 100 years. The documentary Stephen Hawking: Expedition New Earth, will air this summer as part of BBC’s Tomorrow’s World season and will showcase that Hawking’s aspiration “isn’t as fantastical as it sounds,” according to BBC. For years, Hawking has warned that humankind faces a slew of threats ranging from climate change to destruction from nuclear war and genetically engineered viruses. While things look bleak, there is some hope, according to Hawking. Humans must set their sights on another planet or perish on Earth. [more]
