New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through a solid iron lattice. This unusual behavior makes the core soft, matching seismic observations that have puzzled scientists for decades. The mobility of these light elements may also contribute energy to Earth’s magnetic field. The findings reshape models of Earth’s interior and could apply to other rocky planets.
