What was actually claimed<\/h2>\n\n\n\n
Biondi says his team traced geometric alignments between the pyramids and the known Great Sphinx, then mirrored those lines to flag a second location on the plateau. In that spot, he argues, radar anomalies sit under a compacted sand hill, alongside patterns he interprets as vertical shafts and horizontal passages.<\/p>\n\n\n\n

Even the podcast description stays cautious, calling the target a \u201cpossibly\u201d hidden monument rather than a confirmed discovery.<\/p>\n\n\n\n
Why archaeologists are skeptical<\/h2>\n\n\n\n
So far, there is no excavation, no released dataset for independent review, and no peer-reviewed paper validating a second Sphinx. Fact-check reporting that summarizes the claims stresses that, for now, this is speculation until Egyptian authorities<\/a> allow fieldwork and the results can be verified.<\/p>\n\n\n\nThe blowback is also colored by earlier viral claims about a supposed \u201cunderground city\u201d beneath the pyramids, which experts told AFP did not hold up. In that 2025 dispute, Egyptologist Zahi Hawass called the claims \u201ccompletely wrong,\u201d and radar expert Lawrence Conyers argued that satellite radar pulses cannot map massive structures deep into dense geology.<\/p>\n\n\n\n
Radar satellites are powerful, but they have limits underground<\/h2>\n\n\n\n
Synthetic aperture radar, or SAR, is an active sensor that sends out energy and measures what bounces back, which is why it can image at night and through clouds. NASA notes SAR is widely used for environmental monitoring, and Italy\u2019s COSMO-SkyMed system<\/a> is designed to support emergency management during floods, earthquakes, and wildfires.<\/p>\n\n\n\nBut SAR is not an X-ray machine, and its subsurface sensitivity is often shallow and heavily influenced by moisture and surface conditions. <\/p>\n\n\n\n
A technical overview of SAR in archaeology notes why deserts are a natural testing ground and why systems such as COSMO-SkyMed have limited penetration, and Biondi\u2019s arXiv preprint<\/a> itself acknowledges \u201cpoor\u201d penetration in solid bodies while proposing a workaround based on tiny \u201cmicro-movements\u201d linked to background seismic waves.<\/p>\n\n\n\nGiza is an environmental site, too<\/h2>\n\n\n\n
The Giza Plateau is part of UNESCO\u2019s \u201cMemphis and its Necropolis\u201d listing, covering the pyramids, the Great Sphinx, and thousands of tombs across a fragile desert landscape. Any new trenching or drilling would happen in a space where tourism, traffic, and windblown dust are everyday realities.<\/p>\n\n\n\n
