Earth’s core has slowed so much it’s moving backward, scientists confirm
Deep within Earth lies a solid metal core that rotates independently of the planet’s outer layers, akin to a spinning top within a larger one, enveloped in mystery. Discovered in 1936 by Danish seismologist Inge Lehmann, this inner core’s movement—specifically its speed and direction—has intrigued scientists for decades. Studying seismic waves from large earthquakes has provided insights into its dynamics, revealing fluctuations in its rotation … Continue reading Earth’s core has slowed so much it’s moving backward, scientists confirm
