ScanPyramid finds unknown voids but no internal ramp evidence. ScanPyramid Project used muon tomography to scan the Great Pyramid non-invasively Discovered a previously unknown 30m void above the Grand Gallery Found a 9m corridor near the north face

The ScanPyramid Project used muon tomography to peer inside the Great Pyramid, discovering a 30m void above the Grand Gallery in 2017 and a 9m corridor near the north face in 2023. Jean-Pierre Houdin's internal spiral ramp theory remains unconfirmed by ScanPyramid data.
