Cosmic particles gathered inside Egypt’s famed pyramids could help experts learn about the structure of the ancient monuments. Cosmic ray muon radiography imaging, is one of the methods used by scientists searching for hidden chambers within the pyramids. News.com reports: For the past three months a team of researchers from Egypt, France, Canada and Japan have been scanning four pyramids with thermal cameras to see if they contain unknown structures or cavities. Operation Scan Pyramids began on October 25 to search for hidden rooms inside Khufu — also known as the Great Pyramid — and Khafre in Giza and the Bent and Red pyramids in Dahshur, all south of Cairo. The project is expected to continue until the end of 2016, and applies a mix of infra-red thermography, muon radiography imaging and 3D reconstruction — all of which the researchers say are non-invasive and non-destructive techniques. Heat scans of Egypt’s Great Pyramid Real Thing TV YouTube video: On Sunday, experts revealed new findings on some of the limestone blocks that make up the western flank of the Red pyramid and northern flank of Khufu. “There is a clear separation of temperature on the west face of Red pyramid. The bottom is colder [...]
