In one of his final on-camera appearances, iconic physicist Stephen Hawking issued a warning to humanity about the existential threats we face and how our survival depends on colonizing another planet.
Some scientists, including world-renowned physicist Stephen Hawking, believe that in order to safeguard humanity's future, we need to leave Earth and colonize another planet. But is there an alien world out there that we could call home? How would we travel across the vast distances of space to get there? And what would it take to set up a new civilization? See how visionary scientists and engineers are pushing their imaginations and ingenuity to the limits to prepare humanity for what would surely be its greatest adventure yet.
Stephen Hawking was born on January 8, 1942 (300 years after the death of Galileo) in Oxford, England.
He was a theoretical physicist and cosmologist, renowned for his work on black holes. He ran the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge.
Stephen was diagnosed with ALS, a form of Motor Neurone Disease, shortly after his 21st birthday. In spite of being wheelchair bound and dependent on a computerized voice system for communication, Stephen Hawking continued to combine family life (he has three children and three grandchildren) and his research into theoretical physics together with an extensive program of travel and public lectures. His hope was to make it into space one day.
The award-winning film The Theory of Everything was based on his first wife's memoirs of her life with Hawking. Professor Hawking has also appeared in The Simpsons and The Big Bang Theory.
