Beneath Khafre: Doppler Tomography’s Shocking Find — American Alchemy
Update: 2025-12-07
Description
A radical remote-sensing technique may have revealed kilometer‑deep, spiral tube structures under the Khafre pyramid — and the evidence is in the data. In this 5‑minute summary (originally 2 hours), host Jesse Michels interviews Filipo Biondi (with collaborators Corrado Malanga and Armando Mai) about using synthetic aperture radar (SAR) Doppler tomography and inversion algorithms to turn surface vibrations into subsurface tomographies. Learn how satellite sources (Capella, Umbra, COSMO‑SkyMed, ISI) and cross‑validation with Gran Sasso and Osiris test cases strengthen the claims, why water, piezoelectric effects, and vibration are central to the interpretation, and what practical validation steps (in‑situ seismic campaigns, shaft clearance, muon tomography) are proposed — plus the political and scientific hurdles to permission and peer review. Keywords: Giza, Doppler tomography, SAR, remote sensing, archaeology, tomography, pyramids. Listen now to get the key ideas in minutes.
