In an upcoming TV documentary, British physicist Stephen Hawking revives his prediction that humanity will have to spread out a new home in space within 100 years in order to ensure the species’ survival.
But this time, he’s looking into how it can be done.
The two-part documentary, titled “Expedition New Earth,” is due to air on BBC Two as part of the British network’s revived “Tomorrow’s World” TV series.
Hawking has repeatedly warned of the potential threats facing humanity, including nuclear war, rapid climate change, potential pandemics, catastrophic asteroid strikes and even a robot uprising. That echoes similar warnings issued by Elon Musk, the billionaire founder of SpaceX.
