Episode Details

Earth’s core is spinning in the opposite direction of the planet’s surface — a cosmic pendulum effect revealed by seismic waves from earthquakes. Scientists have tracked this wobble for years, but new research offers clearer insight: the core slows, stops, and reverses, subtly affecting day length. The latest data hints this reversal may have occurred around 20 years ago, though exact timing and causes remain under investigation. This deep planetary dance reminds us that even beneath our feet, forces are reshaping our world — one seismic ripple at a time.
