Did you hear about Earth's inner core? Apparently, it's suddenly switching direction, which is kind of a big deal! Scientists have discovered that the solid metal core at the center of our planet might be rotating in the opposite direction than it used to. This change could mess with our magnetic field and even affect the length of our days a tiny bit. It's still a bit of a mystery, but it's super fascinating how much is going on beneath our feet that we never even think about! Animation is created by Bright Side.
