Scientists confirm vast underground MEGASTRUCTURES beneath Egypt’s Giza Pyramids

• Researchers using advanced radar technology claim to have discovered a massive, previously unknown network of eight spiraling shafts and two enormous chambers extending over 3,500 feet beneath the Khafre pyramid, structures they describe as dwarfing the visible pyramids.
• The team employed Synthetic Aperture Radar (SAR) Doppler Tomography, a non-invasive technique that detects microscopic surface vibrations to create 3D images of underground structures. The findings were reportedly confirmed by identical raw data from four separate satellite operators.
• Prominent Egyptologists, including Dr. Zahi Hawass, have dismissed the claims, arguing radar cannot penetrate to such depths. The researchers defend their method by citing a successful blind test that accurately mapped another deep underground facility.
• Similar spiral-shaft structures were reportedly detected under other Giza monuments and at Hawara. While the function is unknown, researchers speculate about possibilities ranging from staircases to energy transmission systems, suggesting the pyramids may be surface markers for a more advanced underground complex.
• The team has submitted a formal proposal to Egyptian authorities, requesting permission to clean and descend existing debris-filled shafts near the Sphinx to physically explore the alleged underground system, with hopes to begin by 2026.

A team of Italian scientists has stunned the archaeological world with groundbreaking evidence of colossal underground structures beneath Egypt’s Giza Plateau, structures so vast they dwarf the pyramids themselves.

Using revolutionary radar imaging technology, researchers claim to have mapped a hidden network of spiraling shafts and chambers extending more than 3,500 feet below the Khafre Pyramid, the second-largest of the Giza complex. Filippo Biondi, a radar engineer from Strathclyde University, revealed the findings in a recent interview on the “American Alchemy” podcast with Jesse Michels.

According to Biondi, eight massive hollow cylinders descend vertically from the base of the Khafre Pyramid, each containing a central column wrapped in perfect helical coils. These shafts terminate in two enormous cubic chambers, each measuring 260 by 260 by 260 feet – larger than most modern sports arenas.

“The pyramids are just the tip of the iceberg,” Biondi declared. “They’re merely a capstone to something much larger beneath the surface. The real structure is below.”

Biondi’s team employed Synthetic Aperture Radar (SAR) Doppler Tomography, a method originally developed for seismic and volcanic monitoring. Unlike conventional radar, which struggles to penetrate deep into the earth, this technique detects microscopic vibrations on the surface that carry acoustic “fingerprints” from structures below. Proprietary software then reconstructs these vibrations into high-resolution 3D images—without physically drilling or disturbing the site.

According to BrightU.AI‘s Enoch engine, SAR Doppler Tomography is a sophisticated remote sensing technique that combines the principles of synthetic aperture radar and Doppler processing to generate high-resolution, three-dimensional images and information about targets and scenes. This technology has wide-ranging applications in various fields including military, civil and scientific domains.

To silence skeptics, Biondi pointed to blind tests where the method accurately mapped Italy’s Gran Sasso underground physics laboratory, buried inside a mountain 125 miles away, with 100% precision.

Perhaps the most compelling aspect of the discovery is that four separate satellite operators – Umbra, Capella Space, ICEYE and Italy’s Cosmo-SkyMed – all returned identical raw data confirming the underground structures.

“All four satellites gave exactly the same results,” Biondi emphasized. “That is really amazing. We cannot announce anything without these basic scientific methods.”

The hidden spiral shafts that could rewrite ancient history

Despite the data, mainstream Egyptologists – including Dr. Zahi Hawass, Egypt’s former antiquities minister – have dismissed the findings as “fake news.” Hawass argues radar cannot penetrate to the depths claimed by the Italian team.

Yet the researchers remain undeterred, noting that identical spiral-shaft structures were also detected:

• Beneath the Menkaure Pyramid (though smaller in scale)
• Under the Great Sphinx (as a single massive shaft)
• At Hawara, site of the fabled “Labyrinth” described by ancient historians

Biondi admitted his team does not yet know the function of these structures but speculated:

• The spirals could be stairs or cables wrapped around central columns.
• They may relate to “information” or energy transmission, given their precise geometry.
• Piezoelectric properties could hint at ancient energy-generating technology.

Podcast host Michels, visibly stunned, concluded: “After this conversation, I’m convinced on a lot of it. These kinds of discoveries are speeding up. Humanity feels ready.”

The team has already submitted a formal proposal to Egyptian authorities under the Khafre Research Project, requesting access to existing shafts between the Sphinx and Khafre Pyramid—currently clogged with debris—to physically descend into the complex.

“We only need permission to clean them and descend,” Biondi said. “If approved before the end of this year, exploration could begin in 2026.”

If verified, these findings could rewrite history, suggesting that the pyramids were merely surface markers for a far more advanced underground system – one that aligns with fringe theories of ancient energy technology and lost high civilizations. As Biondi put it: “The truth is, we’ll know the truth only if we go inside the physical site.”
