The legendary scientist Stephen Hawking delivering speech this week at the Oxford Union, said that humanity can only survive for another thousand years on planet Earth.
According to him Earth may be doomed after thousand year because of the growing threats, which includes climate change, nuclear wars and excessive use of artificial intelligence, CNN reports said.
“I think the human race has no future if it doesn't go to space," the Daily Express quotes Hawking as saying.
According to the reports of Christian Science Monitor, Hawking says it's a "near certainty" that disaster will strike the human race within a thousand years if it stays on Earth, which he calls "fragile.
" There are some challenges on Earth, such as the depletion of its natural resources, humanity won't be able to overcome, he argues.
“Remember to look up at the stars and not down at your feet," he said Monday.
