British theoretical physicist Stephen Hawking has warned that the human race would face extinction, should it fail to go to another planet to live on. The Honorary Fellow of the Royal Society of Arts, in an interview with Big Think, said that the human race's "only chance for long-term survival" may be to "spread out into space."
"We are entering an increasingly dangerous period in our history," Hawking said, the Huffington Post reported on Saturday. Hawking said the human "survival has been a question of touch and go," in the past and such occasions "is likely to increase in the future." He said with regards to man's rampant use of finite natural resources on the Earth, and his genetic code which "carries selfish and aggressive instincts," he has no way but to choose another planet to reside on. According to scientists getting to the nearest star onboard a chemical-fuel rocket, will take human around 50,000 years. To achieve such a goal within his life span, human needs to develop spacecraft that travels at near-light-speed and protect him from the killing cosmic radiations.
