Filippo Biondi, an engineer and signal‑processing researcher who applies satellite radar tomography to underground imaging. He discusses how satellite SAR and vibration analysis revealed reproducible subsurface structures under the Giza plateau. They cover cross‑checks with multiple satellites, surprising spiral columns and large chambers, plans to clear shafts and use robots, and the broader implications for other ancient sites.

Episode notes
Spiral Columns And Massive Chambers Below Giza
- Tomographies show vertical spiral-patterned columns and huge 80m chambers beneath Khafre and other pyramids.
- These structures appear regular, man-made, and uniform under multiple monuments.
Probe Shafts First With Robots
- Biondi urges in-person exploration and cleaning of existing shafts rather than broad excavation.
- He recommends using robots and drones to safely access and document deep shafts before human entry.
Deep Shafts Reach Uniform Chambers
- Biondi's data shows shafts from surface features descending ~600 meters to horizontal corridors and large chambers.
- He says shafts and corridors are consistent across the three pyramids and the Sphinx.
