Discovery inside Giza Pyramid baffles scientists

Scientists have discovered a secret, giant void hiding inside the Great Pyramid of Giza in Egypt. Located above the pyramid's Grand Gallery, the 30-meter-long void inside Khufu's Pyramid remains a mystery.

Its size suggests it plays an important role in the tomb's structure. It's the first discovery of its kind since the 19th century.

"These results constitute a breakthrough for the understanding of Khufu's Pyramid and its internal structure," the scientists explained in a journal published in Nature.

Scientists uncovered the void as part of the ScanPyramids project that dates back to 2015. The chamber was found using cosmic-ray imaging and by recording subatomic particles, a practice known as muon radiography, which bounces inside the structure providing an outline for 3D reconstruction of the space.

This method allows researchers to visualize the...
