Khufu's Great Pyramid’s Hidden Void Revealed
Using Cosmic Rays Scanning Techniques
Research group of Designated Assistant Professor Kunihiro Morishima and other researchers from Elementary Particle Measurements Section of Advanced Measurement Technology Center (AMTC) has succeeded in seeing through the Egypt’s largest pyramid of Khufu and has found a hidden Void in there by observing cosmic ray muons with nuclear emulsion.
The study is being conducted in the international joint study (participated by Japan, Egypt, France and Canada) called the ScanPyramids program, hosted by the Egyptian Ministry of Antiquities, Faculty of Engineering, Cairo University, and HIP Institute (Heritage, Innovation and Preservation Institute). Japan research group consists of Nagoya University and KEK (the inter-University Research Institute Corporations, High Energy Accelerator Research Corporation).
