LONDON – Physicists discovered a secret chamber inside the Great Pyramid of Giza that is believed to date back millennia, the scientific weekly journal Nature reported on Thursday.
The secret chamber, which could date back to 2560 BC, is estimated to be some 30 meters (98 feet) long and could help explain how the tomb of the Egyptian pharaoh Khufu – who the pyramid is named after – was built.
“To better understand its (Khufu’s) internal structure, we imaged the pyramid using muons, which are by-products of cosmic rays that are only partially absorbed by stone,” researchers said.
The discovery was led by researchers from Egypt, France and Japan.
The 4,500-year-old pyramid was built during the reign of Khufu or Cheops (2550 BC to 2527 BC), the second pharaoh of the Fourth Dynasty of the Old Kingdom of ancient Egypt.
“Despite being one of the oldest and largest monuments on Earth, there is no consensus about how (Khufu) was built,” the physicists said.
