“Just because a mystery is 4500 years old doesn’t mean it can’t be solved.” That is the tagline of a major new project to uncover the secrets of Egypt’s pyramids without damaging a single stone.
Scan Pyramids – launched by the Egyptian Ministry of Antiquities – will deploy an arsenal of non-invasive technologies to probe the structure of four pyramids from Egypt’s Fourth Dynasty (from 2575 BC to 2465 BC). On the Giza plateau, about 20 km south-west of Cairo, it will study the Pyramid of Khafre, along with the Pyramid of Khufu, aka the “Great Pyramid of Giza”, the oldest of the Seven Wonders of the Ancient World. Meanwhile, on the site of Dahshur, around 40 km south of the Egyptian capital, it will investigate the North and South pyramids. (Click to expand the map.)
Despite their global fame and familiarity, these ancient monuments still hold many mysteries. Chief among them is the question of how the ancient Egyptians managed to build these huge edifices. The Great Pyramid of Giza was originally 150 m tall and weighed 5 million tonnes, yet it was constructed in just 25 years. Egyptologists also believe that these pyramids could be concealing hidden chambers, which could house tombs and secret treasures.

Yesterday was day three of the Physics World Mexican adventure and it turned out to be a really exciting 24 hours. Matin Durrani and I visited Teotihuacan – the “City of the Gods”– located 30 miles north-east of Mexico City. We were there to witness some of the closing moments of a 15-year particle physics experiment designed to “see” inside the Sun Pyramid, the world’s third biggest pyramid by volume.
