Leaking Gold and Superionic Solids: What We Just Learned About Earth’s Core

Researchers at the University of Southern California have discovered that Earth’s inner core is less solid than previously thought, exhibiting “mushy” characteristics and undergoing structural deformation, according to a study published in Nature Geoscience. Analyzing seismic data, the team found that the outer layer of the inner core is changing shape and shifting, challenging the long-held consensus that it is a completely rigid, uniform sphere.
