The Joe Rogan Experience #2443 - Filippo Biondi
Jan 23, 2026
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
New Satellite Doppler Tomography Works
- Filippo Biondi developed a satellite Doppler tomography method that extracts subterranean structure from surface vibration entropy.
- He applies focused SAR processing to convert coherent surface vibrations into detailed underground images.
First Tests At Khufu Led To Wider Scans
- Biondi first used the method on Khnum-Khufu (Khufu) pyramid in 2019 and published peer-reviewed results in 2020.
- He then expanded scans across the entire Giza Plateau and found consistent deeper structures.
Cross-Satellite Validation Strengthens Findings
- Biondi validated findings across multiple satellites (Cosmo-SkyMed, Capella) to rule out sensor artifacts.
- He reports over 200 scans with uniform results confirming the underground features.
