Cosmic rays reveal 'hidden' 30-foot-long corridor in Egypt's Great Pyramid
Cosmic rays and photos from an endoscope have revealed a "hidden" corridor inside the Great Pyramid of Giza's north face, above the pyramid's ancient entrance, new research finds.
The Great Pyramid was built on orders of the pharaoh Khufu (ruled circa 2551 B.C. to 2528 B.C.) on the Giza plateau and today is about 456 feet (139 meters) high. It is the only surviving wonder of the ancient world and was the tallest building on Earth until 1311, when England's Lincoln Cathedral's 525-foot-tall (160 m) central tower was completed.
A new study reveals that, just above the ancient entrance to the pyramid, there is likely a horizontal chamber that runs for 30 feet (9 m) in length and is 6.6 feet by 6.6 feet (2 by 2 m) in width and height. It is located behind a chevron-shaped structure that is visible outside the pyramid, according to the study, published Thursday (March 2) in the journal Nature Communications.
To learn more about the void, the scientists inserted an endoscope into the corridor to peer inside on Feb. 24 , they announced in a statement. But so far, the team has not found any artifacts inside the corridor, they told Live Science.
"The first pictures taken with the endoscope seem to show there is nothing, but we cannot see all the room precisely yet," study first author Sébastien Procureur, a physicist with the French Alternative Energies and Atomic Energy Commission (CEA), told Live Science in an email. Read More…
