For years, measurements pointed to a hidden cavity in the famous Cheops pyramid in Giza, Egypt, near Cairo. Now an international research team has discovered a previously unknown chamber. The Technical University of Munich (TUM) announced that an endoscope passed through a narrow gap between stones confirmed the existence of an astonishingly large chamber.
Last but not least, the find is particularly important because the Egyptian pyramid is considered one of the best studied structures in the world, the TUM scientists, who were involved with the research work in Egypt with a team, said on Thursday.
Room is bigger than expected
According to the first estimates, the new corridor above the actual entrance to the pyramid even exceeds the initially assumed length of at least five meters. Discovering a cavity in a pyramid is something special — especially on this scale, said Christian Große of the chair for non-destructive testing at TUM, according to the announcement.
Since 2019, the Munich-based company has been part of the international research team ScanPyramids, which has been investigating Egyptian pyramids using various means and technologies since 2015. Measurements with muon tomography, an imaging method for three-dimensional imaging of large-volume objects, already suggested the existence of a cavity.
For a closer investigation, the TUM team led by Christian Große now used methods such as radar and ultrasound, which the researchers say made important contributions to the discovery.
