Summary
Earth’s inner core might be cooling faster than we thought, thanks to new findings on bridgmanite’s heat-conducting abilities. This mineral, abundant in the lower mantle, could be acting like a super-efficient radiator, speeding up core solidification. The implications? Our models of plate tectonics, magnetic fields, and even the timeline of Earth’s geological history may need a major rewrite. Scientists simulated these extreme conditions in labs using diamond anvil cells, revealing surprising thermal properties. This could mean Earth’s internal engine is winding down sooner than expected — reshaping how we understand our planet’s future.
