00:00NASA just used a supercomputer to predict exactly when the world will end.
00:04And the answer?
00:05It's chilling and far, far away.
00:08Or is it?
00:09According to 400,000 computer simulations,
00:12Earth will become uninhabitable in the year 1000-20021.
00:16That's a billion years from now.
00:18Sounds comforting, right?
00:19But here's the twist.
00:21Scientists say we won't make it anywhere near that long.
00:24Between rising temperatures, plummeting oxygen levels, and toxic air,
00:28climate change might wipe us out long before the sun does.
00:31And speaking of the sun, that's our ultimate executioner.
00:35Researchers from University College London and Warwick
00:37believe it will either tear Earth to shreds or swallow us whole.
00:41As the sun runs out of fuel, it expands, pulling Earth in like a death spiral.
00:46Just like the moon creates tides, Earth tugs on the sun,
00:50and that cosmic tug-of-war could doom us.
00:52So while your great-great-great-grandkids might be safe,
00:55the sun has a brutal end planned for our planet.
00:57And unless we find another home, it's just a matter of when, not if.
