Renowned British physicist Stephen Hawking has warned that Humans will need to leave Earth and colonise another planet within the next 100 years to escape from asteroid strikes, overpopulation and drastic effects of climate change. Hawking along with his former student Christophe Galfard will be travelling the world to find out how humans could survive in outer space in a documentary called ‘Expedition New Earth’, a part of BBC’s new science season Tomorrow’s World.
Stephen Hawking claims in the series that time is running out for humanity on the Earth and that they would have to leave the planet in order to survive. Hawking has previously warned of drastic effects of the aggressive instincts of humans, especially with the fast pace of growth in technology. He warned of the chances of a nuclear or biological war and added that only a world government would have a chance of preventing this impending doom. Hawking also noted that humans may lack the skills as species that are required for survival.
In fact, billionaire Elon Musk who is hoping to establish a settlement on Mars within the next few decades through his aerospace firm SpaceX, also stated in 2016 that history suggests the possible occurrence of a doomsday event in the future that will make survival on earth almost impossible. The BBC show Tomorrow’s World would be returning to television after 14 long years. The show had been on air for almost 38 years. The new season will mainly aim to find Britain’s greatest invention and for the same, it will be taking the public’s vote on the innovation that has been the most influential in their lives. Two of its episodes would also explore the science of changing gender and whether it is possible to cure a psychopath.
