It has long been rumored that there's much more to the Great Pyramid at Giza in Egypt than meets the eye, such as hidden corridors and chambers.
Scientists working with the Operation ScanPyramids project say they've discovered cavities in the structure, perhaps indicating the fabled spaces really do exist.

Researchers hailing from Heritage, Innovation and Preservation, a nonprofit group headquartered in Paris, and Cairo University's Faculty of Engineering employed a number of non-invasive advanced technological methods in locating the voids.
One is said to be behind the pyramid's north face and the other along the ancient structure's northeast flank.
Some experts are not convinced the findings will ultimately lead to a redefining of the tomb's interior.
In speaking to Seeker, a former antiquities minister noted:"I think there are no secret rooms and these anomalies have to do with the way the pyramid was built," but also suggested further research be conducted.
