Italian scientists created global buzz earlier this year when they announced that a huge underground system may sit thousands of feet beneath Egypt’s Giza Plateau. Their claim suggested that the area below
the pyramids could hold deep shafts and chambers larger than modern stadiums.
Now Filippo Biondi, the radar engineer behind the project, has shared new proof that he believes supports their findings. In a recent interview on Jesse Michels’ American Alchemy podcast, he said the data collected so far points to the same hidden structures underground.
Multiple Satellite Teams Found the Same Results
Biondi explained that four satellite companies, Umbra, Capella Space, ICEYE and Italy’s Cosmo-SkyMed, recorded matching images using his radar method. “All four satellites gave the same results,” he said in the interview. “That is really amazing. We cannot announce anything without these basic scientific methods.”
His team uses a technique he developed called synthetic aperture radar Doppler tomography. Instead of sending radar through the ground, the method reads tiny surface vibrations. Those vibrations carry sound patterns from objects deep below, helping computers build 3D images even when the radar itself does not enter the soil.
What the Scans Appear to Show
According to Biondi, the images show eight giant hollow shafts running straight down from the Khafre pyramid. Each one has a centre column wrapped in perfect spiral coils. The shafts seem to end more than 3,500 feet below in cube-shaped rooms measuring 260 feet on each side.
“The pyramids are the tip of the iceberg,” he said. “It’s just a hat to complete something that is located underneath. The substance is below.”
When asked if the spirals could be natural, he replied, “100 per cent. It’s man-made. You do not find perfect coils like this in geology.”

Experts Remain Sceptical
Many well-known Egyptologists, including Dr Zahi Hawass, have rejected the findings and called them “fake news”, according to The Daily Mail. Hawass said the radar technology cannot reach the depths claimed by the Italian group. Still, the team says they have seen similar structures under the Menkaure pyramid, under the Sphinx, and even 30 miles away at Hawara, known as the Labyrinth.
Team Pushes for Physical Exploration
Biondi said they do not know the purpose of the shafts but suggested the coils could be stairs or cables. “I can say that this structure, the tubes extending beneath the pyramid, seems to be related to information,” he said. “Generating energy is a kind of information. Information is everything.”
He added that blind tests proved his method works, including a perfect read of Italy’s Gran Sasso underground lab. The team has now submitted a proposal to Egypt to clear old shafts filled with debris. “We only need permission to clean them and descend,” Biondi said. If approval comes soon, he believes real exploration could start in 2026.
Podcast host Jesse Michels ended the interview by saying, “After this conversation, I’m convinced on a lot of it. These kinds of discoveries are speeding up. Humanity feels ready.”
