Stephen Hawking to Human Race: Move to Outer Space or Face Extinction (VIDEO)

Posted: Updated:

Is the future of the human race in outer space? Theoretical physicist Stephen Hawking, in an interview with Big Think, warns that if humans can't find another planet to inhabit, they will face extinction.


Because we are rapidly depleting the finite natural resources that Earth provides, and because our genetic code "carries selfish and aggressive instincts," our "only chance for longterm survival" may be to "spread out into space."

But how do we get there? Scientists estimate that it would take roughly 50,000 years to make it to the nearest star, if we traveled using chemical-fuel rockets. To arrive within our life span, humans would need the technology to travel at near the speed of light and to remain shielded from cosmic radiation for the duration of the journey.
