New cosmic-ray scan of the Great Pyramid of Giza could reveal hidden burial chamber

A new ultra-powerful scan of the Great Pyramid of Giza using cosmic rays could reveal the identities of two mysterious voids inside.

The largest of the two voids is located just above the grand gallery — a passageway that leads to what may be the chamber of the pharaoh Khufu — and is about 98 feet (30 meters) long and 20 feet (6 m) in height, according to previous pyramid scans. Archaeologists are uncertain as to what they will find in the void, which could be one large area or several small rooms, they said. They also hope to find out the function of that void; the most fantastic possibility is that the opening is the hidden burial chamber of Khufu. A more mundane possibility is that the cavity played some role in the building of the pyramid.
