Scientists discover superionic phase in Earth's inner core

Scientists have discovered a new state of matter in Earth's inner core. Experiments suggest it is not entirely solid, but may contain atoms in constant motion. This superionic phase allows some atoms to move like a liquid within a solid structure under extreme pressure. This finding helps explain seismic wave behavior and the core's apparent mechanical softness. The discovery challenges the traditional view of a static inner core. Further research is needed, but the lab results align with seismic observations, supporting the superionic phase hypothesis.
