STEPHEN HAWKING WARNS WE HAVE 100 YEARS TO LEAVE EARTH

Renowned physicist Stephen Hawking has warned that humanity needs to become a multi-planetary species within the next century in order to avoid extinction.

Hawking made the prediction in a new documentary called Expedition New Earth, which is set to be released this summer as part of the BBC’s Tomorrow’s World science season.

Existential risks include climate change, overpopulation, epidemics and asteroid strikes, according to Hawking.

Hawking predicted last year that the chance of a species-ending event on Earth was a “near certainty” when all possibilities were taken into consideration.

“Although the chance of disaster to planet Earth in a given year may be quite low, it adds up over time, and becomes a near certainty in the next 1,000 or 10,000 years,” Hawking told the Oxford University Union in November.

“By that time, we should have spread out into space and to other stars, so a disaster on Earth would not mean the end of the human race.”

Despite the dire warning, Hawking did have some positive news for the assembled students. He pointed to how our fundamental understanding of the universe has advanced in his lifetime and said it is a “glorious time to be alive and doing research into theoretical physics.”

He added: “Our picture of the universe has changed a great deal in the last 50 years and I am happy if I have made a small contribution. The fact that we humans, who are ourselves mere fundamental particles of nature, have been able to come this close to understanding the laws that govern us and the universe is certainly a triumph.”
