Cosmic-ray particles reveal secret chamber in Egypt's Great Pyramid

Physicists have used the by-products of cosmic rays to reveal a large, previously unidentified chamber inside the 4,500-year-old Great Pyramid in Giza, Egypt. The find is the first discovery since the nineteenth century of a major new space inside the pyramid.
Egyptologists have been quick to dismiss any idea of finding lost treasure in the 30-metre-long void. “There’s zero chance of hidden burial chambers,” says Aidan Dodson, an Egyptologist at the University of Bristol, UK, who studies ancient Egyptian tombs. But experts hope that the finding will lead to significant insights into how this spectacular pyramid was built.
The Great Pyramid was constructed by the pharaoh Khufu (also known as Cheops), who reigned from 2509–2483 BC. Constructed from limestone and granite blocks, and rising to 139 metres, it is the oldest and largest of the Egyptian pyramids and one of the most impressive structures to survive from the ancient world.
