Journal retracts paper claiming network of corridors inside the Great Pyramid of Giza
A journal has retracted a paper by two Italian scientists who claimed to have found hidden structures inside of the oldest and largest of the Pyramids of Giza. The study, published in Remote Sensing in October 2022, purportedly used synthetic aperture radar to penetrate the Pyramid of Khufu with energy pulses and process the echoes … Continue reading Journal retracts paper claiming network of…
A journal has retracted a paper published in October 2022 by two Italian scientists, Corrado Malanga and Filippo Biondi. The study claimed to have discovered hidden structures inside the Great Pyramid of Giza using synthetic aperture radar. However, the journal retracted the study on August 10 after a reader raised concerns about methodological issues and statistical errors.
Experts criticized the paper, stating that synthetic aperture radar cannot penetrate through rock and that the researchers' explanation of "micro-movements" to generate a 3D image was technically unsound. The paper had been cited seven times and was mentioned in a 2021 report by Ireland’s Environmental Protection Agency. Despite the retraction, the researchers' 2025 findings were widely shared and covered by various media outlets, leading to claims of a network of chambers and tunnels extending two kilometers in depth beneath the pyramid.
