We've Got 1.75bn Years Left on Earth, Unless We Bollocks it up First

By Gary Cutlack on at

Scientists examining the collapse of other possibly life-supporting planets similar to Earth suggest we've got around 1.75bn years left to lounge about on this particular rock, before changes in the Sun make it impossible to live. Assuming we don't nuke/melt/burn/poison ourselves out of existence first, that is.

The stats come from researchers at the School of Environmental Sciences in the University of East Anglia, who suggest that 1.75bn years is simply the time it'll take for the Sun to expand enough to make living here a complete impossibility thanks to such inconveniences as the sea evaporating and everything dying apart from a few of the hardier microbes.

The study's author, Andrew Rushby, told the Independent that the heating process might take as long as one million years, and that he expects we might have escaped by then anyway, saying: "The optimist in me hopes we’ll still be around to see this. Or that we’ll have migrated to Mars or developed the technology to spread out across the galaxy. But that’s getting into the realms of science fiction."

So we've got until the year 1,750,002,013 to find somewhere else to live. Elon Musk had better get to work on a warp drive. [Independent]
