Mysterious structures under the Pacific: What scientists found beneath the ocean floor could reshape Earth's history

Scientists have uncovered massive, dense rock structures deep beneath the western Pacific, challenging long-held theories about Earth's mantle. Advanced seismic imaging reveals these anomalies, which don't fit current models of subducting tectonic plates. Their existence suggests a more complex and ancient Earth interior than previously understood, prompting a re-evaluation of geological processes.
