Earth's Core Cooling Faster Than Thought | Philadelphia News

Earth’s core is cooling way faster than we thought—about 100 times quicker than when the planet first formed. This rapid chill, driven by heat-boosting mineral bridgmanite in the lower mantle, could be weakening our planet’s magnetic shield. A fading magnetic field means more solar radiation could reach Earth, threatening satellites and life itself. New lab experiments simulating extreme deep-Earth conditions are revealing just how dynamic our planet’s interior really is—and how fast it might change.
