4 reportsHeat flow and direct observations form a case with different strengths and limits. Reports examine which observations support the interpretation and how inverse models are tested, showing how sparse measurements or incomplete records limit certainty.
Radar Evidence Revives Search Beyond Tutankhamun's Tomb
More than 1,200 microgravity readings and ground-penetrating radar surveys have identified low-density anomalies beyond Tutankhamun's burial chamber. The findings are consistent with possible corridors and rooms, but neither the structures nor a connection to Nefertiti has been confirmed by excavation.
NASA tracks Earth's shifting center of mass with satellites
NASA scientists have measured how Earth's center of mass moves by millimeters each year as water, ice, and air shift across the globe, using satellite laser ranging and GPS data.
