Mysterious void discovered in Great Pyramid

CAIRO, EGYPT - OCTOBER 21: Camels and horses stand tied to a fence below the Great Pyramid of Giza on October 21, 2013 in Cairo, Egypt. The Pyramids of Giza, one of the seven wonders of the ancient world and built around 2600 B.C., are one of Egypt's major tourist drawcards. After a summer of violence, tourist numbers across Egypt are at their lowest levels since a 2010 peak in tourism in the country. While Egypt's tourism sector took a dive following the popular uprising that overthrew President Hosni Mubarak in early 2011, occupancy rates of hotels in the capital Cairo and across Egypt have been reported as dramatically down since the Egyptian military's overthrow of President Morsi in July. In 2010, tourism represented 13% of Egypt's economy and employed one in seven of the country's workers. (Photo by Ed Giles/Getty Images).
