As search for habitable planets have gained more speed in recent years, scientists from time to time have emphasized the need to move away from earth as the threats of extinction is increasing at an alarming rate. Stephen Hawking recently said that if humane race has to survive, we need to leave the planet within next 100 years.
Hawking’s new prediction come during the documentary tephen Hawking: Expedition New Earth under the Tomorrow’s World by BBC. In the documentary, Hawking pointed out increased amount of terrestrial risks that include climate change, overpopulation, epidemics, and asteroid strikes.
Interestingly, this new prediction is significantly lower than the 2016 prophecy that predicted that human civilization will last in the planet for another 1,000 years. In the documentary, Hawking emphasized the importance of technological innovation as he referred to advances in astronomy, biology, and rocket technology to reach out to new planets including Mars. The documentary also discusses futuristic technologies including human hibernation and plasma rockets.
Back in 2008, Hawking had said that Mars is the next target for human colonization during NASA’s 50th anniversary. While the colonizing in different planets would require technological advancements different fields such as safe transportation, communications, habitat, food, and healthcare, Hawking suggested Moon and Mars as the two possible choices in case of any catastrophic event come into play in future.
The human mission to mars is already in progress as Elon Musk recently announced that SpaceX’s main goal is to establish a human settlement on the red planet in the coming years.
