![Something Is Wrong With Earth’s Core
A huge, red-hot metallic sphere about the size of the Moon—roughly as hot as the surface of the Sun, around 11,000 °F . It lies deep beneath our feet, far beyond the reach of any drill—at the very center of the Earth. This is Earth’s core
Its activity drives plate tectonics, generates Earth’s magnetic field, and influences life on the surface. For a long time, the inner core was thought to be stable: solid, slowly growing, and rotating almost in step with the planet. However, recent publications [papers] challenge the smoothness of this timeline. So what would happen to our world if it began to behave differently—slowing down or even reversing the direction of its motion?
