The scientists work with ScanPyramids, a mission under the French Heritage, Innovation and Preservation Institute, the Faculty of Engineering of Cairo, and the Egyptian Ministry of Antiquities. The group applied a physics technique that allowed them to track particles called muons, which come from cosmic rays striking atoms in the upper atmosphere. Once the particles fall and pass through different materials, they lose energy, causing them to slow and decay.
