As if Monday isn't depressing enough, you'll might as well know what English theoretical physicist Stephen Hawking has to say about humanity's fate on Earth.
Back in November Hawking—who lives with Lou Gehrig's Disease—predicted that we have a solid 1,000 years.
Now, in his forthcoming documentary for the BBC, Expedition New Earth, he's gone and revised it down a bit—to 100 years.
"Professor Stephen Hawking thinks the human species will have to populate a new planet within 100 years if it is to survive," the BBC confirmed.
"With climate change, overdue asteroid strikes, epidemics and population growth, our own planet is increasingly precarious."
According to Hellogiggles, Hawking's new documentary looks at evolving science and technology regarding biology, astronomy and human hibernations, as well as the possibilities of life on Mars and how we could go about colonising the planet—something he refers to as, 'Planet B'.
Over the years, Hawking has been increasingly vocal about our need to find a 'Planet B', once calling for humans to colonise the moon and find a way to settle Mars which he called the 'obvious next target' in 2008, according to New Scientist.
In addition, he's pointed out how the rapid development of artificial intelligence will significantly contribute to the downfall of planet Earth and the human race.
"I think the development of full artificial intelligence could spell the end of the human race," Hawking told the BBC in a 2014 interview.
"Once humans develop artificial intelligence, it will take off on its own and redesign itself at an ever-increasing rate," he warned. "Humans, who are limited by slow biological evolution, couldn't compete and would be superseded."
So there you go. The countdown has started.
