ScanPyramids Discovers the 'Big Void'
Detailed Account
Using cosmic-ray muon tomography, the ScanPyramids project discovers a previously unknown large cavity above the Grand Gallery — at least 30 meters long, the largest internal structure found in the Great Pyramid since the 19th century. The void's purpose is unknown. Its position — directly above the Grand Gallery's acoustic resonance chamber — is consistent with theories proposing the pyramid had functional internal systems. The void has never been physically accessed.
