Why these satellite scans could rewrite pyramid history
Joe introduces Filippo Biondi and the controversial claim: satellite-based radar tomography suggests large, structured formations beneath the Giza pyramids. Biondi frames the work as potentially paradigm-shifting if the measurements hold up.
Biondi’s engineering background and path into the project
Biondi explains his education in telecommunications engineering and his PhD work, then connects it to his long-term experience with radar and synthetic aperture radar (SAR). Joe clarifies his military-adjacent work and how that expertise translated into archaeological scanning.
How the method works: SAR, Doppler focusing, and “vibration” tomography
Biondi gives a simplified explanation of satellite SAR imaging, Doppler effects, and how signal processing can be used to infer subsurface structure. He claims the method doesn’t ‘penetrate’ directly but reconstructs underground features from surface vibration/entropy patterns.
From Khufu’s pyramid to the wider Giza Plateau: timeline and strategy shift
Biondi describes how the collaboration began in 2018, with first scans in 2019 focused on Khufu (Cheops) to validate interior imaging. After publishing a peer-reviewed paper in 2020, they expanded scanning to the entire plateau, prompted by collaborator Armando Mei.
Validation check: matching known chambers and internal features in Khufu
Joe presses on whether the technique reproduces known internal chambers and dimensions. Biondi claims it correctly identified features like the Grand Gallery, Queen’s Chamber, and King’s Chamber, plus a multi-layer structure they call the “Zed.”
The big reveal: deep scans under Khafre and the appearance of “columns” and spirals
Biondi explains that deeper algorithm settings on Khafre led to unexpected vertical structures with regular spacing and spiral characteristics. He describes an initial six-month period of skepticism, worried the results could be artifacts, until repeated confirmations appeared.
Cross-satellite replication: 200+ scans and the decision to disclose
To test whether results were sensor-specific, the team used multiple satellite constellations beyond Italy’s COSMO-SkyMed, including Capella Space. Biondi says consistent outputs across 200+ scans drove them to go public and reinforced confidence in the method.
Pushback, “gatekeeping,” and benchmarks proving the technique (Gran Sasso lab)
Joe argues the resistance is institutional and bias-driven; Biondi says the implications may simply be “too huge.” They point to benchmarks—especially imaging the Gran Sasso underground laboratory—as evidence that the approach can reconstruct known subsurface facilities.
Reading the images: 3D reconstructions, coils, and 80-meter chambers
With images on screen, Biondi explains axes (depth vs. distance) and how repeated tomographies were combined into a 3D interpretive model. He describes spiral/coil-like structures and claims huge chambers—roughly 80×80×80 meters—at the base of the vertical formations.
A non-invasive access plan: shafts near the Sphinx going ~600 meters down
Biondi proposes investigating existing shafts between the Sphinx and Khafre rather than drilling new holes. He claims these shafts descend ~600 meters, connect to chambers and horizontal corridors, and could be cleared safely using robots and drones.
Permits, funding, and operations: a $20M robotic exploration proposal
They discuss submitting a formal proposal to Egyptian authorities and partnering with University of Ferrara and geologists for conventional in-situ verification. Biondi estimates about $20M to clean shafts and deploy robotic systems, emphasizing minimal disruption to tourism and heritage.
Purpose and age speculations: Zed “filter,” vibration theory, Zep Tepi, and the Great Flood
Biondi and Joe pivot into speculative interpretation: a “Zed” structure acting like a low-pass filter for vibrations and the granite box used for induced altered states. They discuss older chronologies (Zep Tepi), flood evidence (salt, debris), and links to Younger Dryas impact hypotheses.
Scaling the approach worldwide: other megalithic sites, mystery shafts, and global satellite coverage
The conversation broadens to scanning other locations (Pumapunku, Göbekli Tepe, Sacsayhuamán) and a reported megalithic shaft in Russia (Kharahora/Karakora). Biondi argues satellites enable global surveying, while Joe emphasizes how many discoveries may still be hidden underground.
Technical proof reel: tunnels, dams, and underground infrastructure reconstructions
Biondi walks through additional validations: detecting the Gotthard tunnel system, monitoring the Mosul Dam’s internal tunnels and turbines, and again the Gran Sasso underground lab. These examples are presented as empirical support that his processing can resolve known underground geometries.
Wrap-up: controversy as catalyst, future replication, and where to follow the work
Joe frames the controversy as beneficial because it forces scrutiny and could accelerate verification. Biondi shares his website for deeper dives and reiterates openness to replication, ending with plans to revisit once more results emerge.
