huge void has been discovered in the Great Pyramid of Giza

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.

They said the newly discovered internal structure was at least 100 feet long, and located above a hallway measuring about 155 feet long called the Grand Gallery, one of a series of passageways and chambers inside the immense pyramid. The researchers said it constitutes the first major inner structure found in the Great Pyramid since the 19th century.
