Mysterious hot spots detected on ancient Pyramids in Giza could reveal hidden chambers

Thermal mystery: Cheops, the largest of the Great Pyramids of Giza, on the outskirts of Cairo

Mystifying 'hot spots' have been detected on Egypt's Giza pyramids using thermal scanning equipment.
Two weeks of research using the state-of-the-art heat detecting equipment revealed the anomlaies, including a major one in the largest pyramid, Cheops.
Egyptian Antiquities Minister Mamdouh el-Damaty and technical experts working on the project showed the thermal differences in the pyramid in a live camera presentation to journalists.
The scanning showed "a particularly impressive one (anomaly) located on the Eastern side of the Khufu pyramid at ground level," the ministry said in a statement.
The thermal scanning was carried out during sunrise, as the sun heats the structures from the outside, and then during sunset as the pyramids are cooling down.

The speed of the heating and cooling phases was used to uncover "hypotheses" such as internal air currents, the different building materials used, and - perhaps most intriguingly - empty areas in the pyramids.
"The first row of the pyramid's stones are all uniform, then we come here and find that there's a difference in the formation," said Mr el-Damaty, pointing at the three stones showing higher temperatures.

While inspecting the area, he said they found "that there is something like a small passage in the ground that you can see, leading up to the pyramids ground, reaching an area with a different temperature.
