In the last 100 years or so, humanity has accomplished a lot of innovations. We learned to how to fly (at least with the help of airplanes), build huge machines, cure diseases, and develop computers, the Internet, and smart devices.
In the same time, we have caused our fair share of destruction, too. In the form of several wars — two of which were World Wars — and recently, man-made climate change.
Now, renowned physicist Stephen Hawking thinks we have 100 years left before doomsday — and we need to get off the Earth long before that comes to pass.

This is not the first time Hawking has given a doomsday prediction. In recent years, he has warned about how super artificial intelligence (AI) could end humankind and how contacting extraterrestrial life could go bonkers for humanity.
Previously in November of last year, he said we have 1,000 years to leave Earth. Now, he has cut it down to 100 — leaving us to wonder just how bad the past six months have been. They’d arguably have to have been pretty bad for Hawking to drastically cut our time on Earth by 900 years in one fell swoop.
The details of Hawking’s latest doomsday warning will be featured in a new BBC documentary airing on June 15 called Expedition New Earth, where he suggests that humanity needs to be a multi-planetary species within the next century in order to survive.
