Scientists using an imaging method based on cosmic rays have detected a large and enigmatic internal structure in the last of the Seven Wonders of the Ancient World still standing, the massive Great Pyramid of Giza on the outskirts of Cairo, Reuters reports in the following story:
Researchers announced the discovery on Thursday but noted they did not know the purpose, contents or precise dimensions of what they are calling a “void” or “cavity” inside the pyramid, built as a monumental tomb around 2560 BC.
To look inside the pyramid, the scientists used an imaging technique called muon tomography that tracks particles that bombard Earth at close to the speed of light and penetrate deeply into solid objects.
They announced the newly discovered internal structure was at least 100 feet (30 meters) long, and located above a hallway measuring about 155 feet long (47 meters) called the Grand Gallery, one of a series of passageways and chambers inside the immense pyramid. The researchers said it constitutes the first major inner structure found in the Great Pyramid since the 19th century.
