A controversial 2022 scientific paper claiming to have mapped the internal structure of the Great Pyramid of Giza (Pyramid of Khufu) on the Giza Plateau in Egypt using satellite radar data has been officially retracted by the journal 'Remote Sensing' due to significant methodological errors and statistical flaws. This development does not mean the mysterious voids within the pyramid have vanished; rather, it shakes the credibility of radar measurements from space while once again highlighting the accuracy and importance of physical discoveries made using cosmic rays.
Faulty Signals from Satellite Radar
The study, published by Italian researchers Filippo Biondi and Corrado Malanga, utilized Synthetic Aperture Radar (SAR) data from the COSMO-SkyMed satellite system. The authors claimed that this method allowed them to visualize the pyramid's interior and subsurface with high-resolution three-dimensional tomography, suggesting the discovery of previously unknown structures. However, the journal's editorial board identified methodological deficiencies to a degree that invalidated the study's scientific conclusions. Although the authors appealed the decision, the retraction of the paper has dealt a significant blow to claims of imaging pyramid interiors with satellite data.
Real Voids Proven by Cosmic Rays
Contrary to the retracted paper, the large voids within the Great Pyramid are not entirely imaginary. Research conducted using cosmic ray (muon) tomography as part of the ScanPyramids project definitively proved the existence of a massive void approximately 30 meters long inside the pyramid [1]. This space, located directly above the Great Gallery and referred to as the 'Big Void,' has been repeatedly confirmed by independent teams using modern instrumentation [2]. Similarly, a nine-meter-long hidden corridor behind the triangular stones on the pyramid's north face was scanned and visualized using different physical methods, including muon tomography and electrical resistivity tomography.
Secrets of the Pyramids Solved with Non-Destructive Methods
As Egyptian law strictly protects the Giza pyramids, only non-invasive, non-destructive research methods are permitted in the area. Similar research techniques have been applied to Menkaure (Mycerinus) Pyramid, another monument in Giza, where new voids indicating secret entrances were also detected [3]. With speculative satellite-based claims being discarded, scientists continue to focus on ground-based physical measurements such as cosmic rays, ultrasound, and radar to unravel the true architectural secrets of the pyramids.
