According to the renowned physicist Stephen Hawking, mankind won’t survive for another 1,000 years on Earth unless people move to another planet. He issued the warning at the Monday debate on universe and the origin of people at the Oxford Union. He also mentioned that 2016 was a great year for research in theoretical physics.
“Our perception of the universe has changed drastically over the past 50 years, and I’d be honored if I’ve had some contribution to this,” the well-known physicist said.
As suggested by Hawking, human beings may have less than 200 years to find another planet for survival; if they fail to do so, all the species on Earth will face a risk of extinction.
In the interview he gave for video site Big Think, he said, “It will be difficult enough to avoid disaster in the next hundred years, let alone the next thousand or million.”
“Our only chance of long-term survival is not to remain inward-looking on planet Earth, but to spread out into space.”
According to the famous physicist, there are two types of catastrophes threatening people on Earth. First, there are man-caused catastrophes, such as climate change, nuclear or biological warfare, all of which produce devastating impacts on the planet.
Second, cosmic phenomena, such as an asteroid impact, or a supernova or gamma-ray burst near Earth, could also mean an end to life on out planet.
Last, but not least, an extraterrestrial civilization taking over the planet and claiming its resources could also threaten life on earth, according to Hawking.
The professor concludes that the best back-up plan for survival of the humankind is to have people living on other worlds.
“The human race shouldn’t have all its eggs in one basket, or on one planet,” he told Big Think. “Let’s hope we can avoid dropping the basket until we have spread the load.”
