Potential good news, everyone! It appears possible that when the sun exhausts its hydrogen fuel and expands into a red giant in about 5 billion years, Earth might not be swallowed up.
Using updated models of how aging stars interact with their planets, researchers found that the gravitational forces drawing Earth toward the expanding sun are weaker than older models predicted. That would give the planet more time to drift outward as the dying sun sheds its outer layers into space, potentially avoiding engulfment altogether.
There’s a lot of unknowns and uncertainty in the calculations, but, ya know, fingers crossed.
