Space is hard enough without your brain deciding to play musical chairs inside your skull. New research shows that after months floating in microgravity, astronauts’ brains slide upward and backward a couple millimeters—like their gray matter is trying to escape the helmet. It’s visible to the naked eye, messes with balance big-time (especially after year-long missions), and doesn’t always snap back fully even after six months on solid ground. No headaches or brain fog reported, but hey, your head’s literally reshaping itself up there. Perfect for anyone who always wanted their thoughts to drift a little further from reality.
