A recent study has unveiled a fascinating discovery about Earth's core – an ancient ocean floor wrapping around the core at the core-mantle boundary (CMB), approximately 1,800 miles below the surface. This unexpected structure was revealed through high-resolution mapping of seismic waves in the Southern Hemisphere. P. Geo. Ricardo A Valls, M.
