Last year, scientist Stephen Hawking gave humans a shelf-life of 1,000 more years on Earth.
Apparently, 2017 hasn't been to his liking—as Hawking shaved another 400 years off that prediction.
The world-renowned scientist said Tuesday that he believes humans will only last another 600 years before Earth becomes a "sizzling ball of fire" that marks the end of humanity, The Sun reported.
"We have given our planet the disastrous gift of climate change ... When we we have reached similar crises there has usually been somewhere else to colonize ... But there is no new world, no utopia around the corner," he said. "We are running out of space, and the only places to go to are other worlds."
