This was one of my favorite interviews. Radar engineer Filippo Biondi just dropped the most explosive finding ever reported at Giza: eight clearly man-made, tube-like structures plunging more than a kilometer beneath the Khafre Pyramid and ending in huge 80-meter chambers. The structures are obviously artificially engineered and the synthetic aperture radar Doppler tomography technique he used has precedent in accurately predicting underground structures (in both commercial and defense use cases). The Egyptian ministry of culture is extremely afraid this finding might rewrite their history.
