A huge void has been discovered in the Great Pyramid of Giza by scientists using an imaging method based on cosmic rays.
Experts announced the find on Thursday but have admitted they don’t know what the cavity inside the pyramid, built as a monumental tomb around 2560BC, is for.
To see inside the pyramid, the scientists used an imaging technique called muon tomography that tracks particles that bombard Earth at close to the speed of light and penetrate deeply into solid objects.
