Under Giza’s Surface: SAR, Muons, and Hidden Voids — American Alchemy

Hook: New radar techniques and muon scans could rewrite what’s beneath the Giza plateau — if the data and processing hold up. This condensed summary (from the full episode, ~1 hour, to a 15-minute version) captures Jesse Michels’ roundtable with Filippo Biondi (Doppler/SAR tomography) and Jeffrey Drum (industrial-chemical pyramid hypothesis). You’ll learn how synthetic aperture radar, phonon-based vibration reads, and muon tomography offer complementary but sometimes conflicting views; why heavy GPU reprocessing, incidence angles, and control scans matter; and how geology, water, and granite alter interpretations. Key takeaways: validation protocols, cross-method triangulation, and minimally invasive robotics for ground truth. Hosts and guests map practical next steps—rescan targets, share data and code, and fund compute clusters. Listen now to get the key ideas in minutes.
