Earth’s Core Cooling Faster Than Thought | Orange County News

Earth’s core is cooling twice as fast as scientists once thought, thanks to a newly discovered heat-transfer property in bridgmanite — the most abundant mineral in the lower mantle. This accelerated cooling could weaken or even collapse Earth’s magnetic field sooner than expected, threatening our protection from solar radiation. The findings, revealed through high-pressure experiments and simulations, reshape our understanding of planetary evolution and raise urgent questions about Earth’s long-term habitability.
