Okay, this is wild: scientists say Earth is already 82% through its life-friendly phase! Forget the slow fade we learned in school—new models predict our planet’s habitable window could slam shut way before the Sun actually dies. The real kicker? They’ve even named a year (a billion years from now) when life ends for good. It’s not just climate change—physics and the Sun’s slow brightening are the ultimate bosses here. Suddenly, our time on Earth feels a lot more precious! #Science #EarthScience #FutureOfEarth
