Using muon particles Physicist Kunihiro Morishima of Nagoya University, Japan, and his colleagues have discovered a previously unknown chamber in the Great Pyramid of Khufu. They set up a device that detects muon particles. If stone is found, there is fewer muon particles. However if there is an empty space, more muon particles will be detected. This is first major discovery of a space since the 19th century. Many theories abound as to what the chamber is and what it was used for. It is highly unlikely that it will contain any artifacts such was found in Tutankhamun‘s tomb but it will still give us information on the building of this magnificent building.
