Earth's Core Not Fully Solid? Rare "Superionic" State Unveiled

• Earth's inner core may not be fully solid, but exists in a rare "superionic" state, challenging previous assumptions.
• Superionic matter behaves as both solid and liquid: heavy atoms form a stable lattice while lighter atoms flow freely.
• This state explains puzzling seismic wave behavior in the inner core and was confirmed by recreating extreme core conditions.
• The discovery has significant implications for understanding Earth's evolution, heat transfer, and magnetic field dynamics.
• Superionic matter could also exist in other planets, potentially influencing their magnetic fields and habitability.

Why It Matters: Earth's inner core is likely a dynamic "superionic" state, reshaping our understanding of the planet.
