Dr. Filippo Biondi is a satellite radar specialist who has spent more than three years scanning the Giza Plateau using synthetic aperture radar data from multiple commercial satellite systems. His work on the plateau has already produced significant subsurface findings. In the last month, working with independent researcher Damiano Pieracci who identified the candidate location, Biondi turned his processing capabilities toward a mound in the Western Cemetery at Giza - and what he found stopped him.The geometric case he presents is precise. Working from the known position of the existing Sphinx, he established a series of line segments connecting it to the proposed second location. What emerged was a set of relationships that should not exist by chance - parallel lines, proportional segments, and equivalent areas that only hold if the proposed location is correct. Move the second point by even a small distance in any direction and every relationship collapses simultaneously.His working hypothesis, shared with around 80% confidence while processing is still ongoing, is that the two structures face in opposite directions - one oriented toward the sunrise, one toward the sunset. The candidate site is a compressed sand mound in the Western Cemetery, a part of the plateau that receives very little research attention. Biondi has scans of the location that he is not yet ready to release pending completion of the analysis, which he intends to present in full at a conference in Bologna in June 2026.
