Earth's Core Cooling Faster Than Thought

Earth’s core might be cooling faster than we thought, thanks to new lab findings showing bridgmanite—a key mineral in the lower mantle—conducts heat far more efficiently than previously believed. This could accelerate mantle convection, speeding up plate tectonics, reshaping our understanding of planetary evolution, magnetic fields, and even life’s long-term survival. Scientists are racing to refine models as Earth’s internal heat engine may be running out of fuel sooner than expected. Support the show:Get a discount at https://solipillow.com/discount/dnn.
