Earth’s Inner Core Spins Differently
Earth’s inner core is spinning differently—and possibly reversing—relative to the planet’s surface, according to new seismic data analysis. First spotted 40 years ago, this differential rotation is now being refined, revealing a link to Earth’s magnetic field. The discovery reshapes our understanding of planetary dynamics, offering clues about how Earth’s core influences everything from geology to life. Scientists are racing to pinpoint the mechanisms behind this movement using ever-more precise seismic records, revealing a planet far more active and mysterious than we thought. Support the…
