A team of Italian scientists stunned the world last March when they announced the discovery of a vast underground complex stretching nearly 3,500 feet beneath Egypt\u2019s Giza Plateau<\/a>, connecting chambers said to be the size of city blocks.<\/p>\n And now Filippo Biondi \u2014 the radar engineer behind the imaging technique \u2014 has come forward with what he says is compelling evidence.<\/p>\n In a recent appearance on Jesse Michels’ American Alchemy podcast, Mr Biondi revealed that four independent satellite operators \u2014Umbra, Capella Space, ICEYE, and Italy\u2019s Cosmo-SkyMed \u2014 each produced matching raw tomography data indicating the same subterranean structures.<\/p>\n Mr Biondi said: \u201cAll four satellites produced exactly the same results. That\u2019s truly remarkable. We can\u2019t announce anything without these fundamental scientific checks.”<\/p>\n READ MORE: EasyJet adds new cheap flights to beautiful beach resort with 22C January weather<\/a>READ MORE: Egyptian Book of the Dead unearthed in cemetery and experts won’t say what it contains<\/a> Using a technique he pioneered \u2014 synthetic aperture radar Doppler tomography \u2014 Mr Biondi\u2019s team analyses microscopic vibrations on the Earth\u2019s surface. According to him, these vibrations carry acoustic \u201cfingerprints\u201d from objects thousands of feet underground, enabling software to reconstruct 3D images even though the radar signals never actually penetrate the soil.<\/p>\n The scans, he claims, depict eight enormous hollow cylinders descending vertically from the base of the Khafre pyramid, the middle of the three great pyramids.<\/a> Each shaft supposedly contains a central column wrapped in precise helical coils and ends more than 3,500 feet beneath the plateau in cubic chambers measuring roughly 260 feet on each side \u2014 larger than many modern sports arenas.<\/p>\n Mr Biondi insisted: \u201cThe pyramids are just the tip of the iceberg. They\u2019re merely a capstone to something much larger beneath the surface. The real structure is below.\u201d<\/p>\n When asked whether the spiral forms might be natural geological features, he responded emphatically: \u201cNot a chance. It\u2019s man-made. You simply don\u2019t see perfect coils like this occurring in geology.\u201d<\/p>\n![\"Filippo](\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/12\/0_Screenshot-2025-03-27-at-064339JPG.jpg\")
