A Mysterious Empty Space(Void) Have Been Discovered in The Great Pyramid of Egypt

Constructed more than 4,500 years ago, the pyramid is believed to have been built as a tomb for the pharaoh Khufu, also known as Cheops.

It is one of three pyramids at the Giza complex on the outskirts of Cairo and is the only one of the Seven Wonders of the Ancient World that remains standing.
Using a technique called muography, researchers have been analysing changes in the density of the rock inside the pyramid.

The cavity above the pyramid's Grand Gallery, which was discovered by Japanese and French scientists and has been described as a "breakthrough", is not obviously accessible and it is not known whether it holds anything of value.
It is approximately 30m long and several metres in height, but the researchers are not describing it as a chamber.
