Filippo Biondi — Italian telecommunications/space engineer who developed a satellite radar tomography (SAR-based 'harmonic radar') method and co-led the controversial research claiming massive structures exist under the Giza plateau.
The gist
Filippo Biondi explains his satellite-based Doppler radar tomography technique, which he says reads vibration data from Earth's surface to image structures deep underground without drilling. He and Joe Rogan walk through scans claiming to show enormous vertical columns with spiral 'coils,' connecting corridors, and football-field-sized chambers roughly 600m to over a kilometer beneath the Giza pyramids and Sphinx. Biondi argues the pyramids are not tombs but resonance devices, citing the 'Zed' as a stone low-pass filter and an antenna that channels vibration into the granite 'sarcophagus,' possibly for out-of-body experiences. The pair tie the findings to a much older timeline (the Zep Tepi king list and the Younger Dryas flood), pointing to salt on the pyramid walls and debris-filled shafts as evidence of ancient flooding. Biondi also presents benchmark validations of his method (a particle-physics lab inside Gran Sasso, the Mosul Dam, a railway tunnel) and floats future scans of other megalithic sites.
Big reveals
- Biondi says his first reaction to the giant column images was skepticism, and the team sat on the results for six months thinking they were noise or artifacts.
- Claims more than 200 scans, using both Italian (COSMO-SkyMed) and American (Capella Space) satellites, returned uniform results before they disclosed.
- States flatly: 'Today we are sure of one thing, that the pyramids are not tombs.'
- Describes shafts between the Sphinx and Khafre pyramid going down roughly 600m to reach huge chambers, claiming structures reach ~1.2km deep.
- Argues the granite box was built to hold a living man and that vibration collapses at its center for an induced out-of-body / 'gateway' experience.
- Dates pyramid construction between the Zep Tepi (~36,000 years ago) and the Great Flood (~11,000-12,000 years ago), personally guessing ~18,000-20,000 years.
- Claims his technique predicted a corridor at the base of the Grand Gallery six months before Zahi Hawass's team officially discovered it.
- Says local authorities in Gubbio, Italy asked him to scan for a suspected buried Roman city near a mini-colosseum.
Things worth remembering
- His method accurately measured a particle-physics laboratory buried 1.4km inside Italy's Gran Sasso mountain, used as a benchmark for accuracy.
- Christopher Dunn's recreated granite vase is reportedly accurate to less than the diameter of a human hair, despite handles ruling out a lathe.
- Biondi estimates cleaning the shafts and exploring below would cost about $20 million, done with drones and robots rather than humans for safety.
- He interprets the 'Zed' as a stone-built low-pass filter and a vibration-domain 'antenna' feeding energy into the chamber below.
- Biondi says he personally tasted salt still on the pyramid walls and believes it is sea salt from an ancient flood.
- Joe cites iridium layers, nanodiamonds and trinitite-like vitrified glass as Younger Dryas impact evidence at uniform global depth.
- Biondi frames cold fusion (Fleischmann-Pons, using palladium) as 'convincing' atoms to fuse naturally versus modern science's 'force' approach.
- Discusses the 'Carakora/Karahora' shaft in Russia's Caucasus, a deep megalithic-lined structure of unknown origin first noted around 2011.
- Used his radar method on Iraq's Mosul Dam, built on water-soluble gypsum, to detect internal tunnels and turbines.
- Biondi directs people to his personal website, harmonicsar.com (named for synthetic aperture radar).
