00:00Discovery of a Big Void in Khufu's Pyramid by Observation of Cosmic Ray Muons by Morishima and colleagues.
00:07A void with a cross-section similar to the Grand Gallery itself,
00:11and a minimum length of 30 meters sitting above the gallery like a secret second corridor.
00:17The signal stood at 5.8 standard deviations, well beyond the threshold physicists demand, before declaring a discovery.
00:25The paper called it the first major inner structure found in the Great Pyramid since the 19th century.
00:32And then in the driest sentence in the history of archaeology, the authors admitted they had no idea what it
00:38was for.
