Two cavities cannot be explained in the Great Pyramid of Egypt

Using modern scanning technology, the researchers discovered two mysterious hollow chambers within the Great Giza pyramid in Egypt.

Group of researchers at Cairo University's Technical Department, Egypt in conjunction with a nonprofit organization The Institute of Heritage, Achievement and Conservation (HIP) confirms the 4,500-year-old Giza Great Pyramid contains two empty cavities. previously known, can contain a corridor-like structure and many other mysterious features, Seeker reported on October 16.

Researchers in the Pyramid Scan (ScanPyramids) project announced the discovery after a year of using many scanning techniques with pyramids built from the Ancient Kingdom (2686 - 2181 BC).

Under the supervision of the Egyptian Antiquities Ministry, the project team used three advanced technologies including muon particle projection, heat measurement and 3D simulation to further explore the Great Pyramid of Giza. They found an empty chamber about 105 m high on the northeast edge of the building and other empty compartments behind the face facing north, on the upper part of the entrance.

"The hollow chamber is shaped like a corridor and can lead high in the pyramid," said Mehdi Tayoubi, founder of HIP Institute. According to Tayoubi, the researchers have not found a link between the two empty chambers.

Built for pharaoh Cheops , also known as Khufu, the Great Pyramid is the largest of the three pyramids on the Giza plateau, outside Cairo. This is also the last wonder left from the ancient world.

In November 2015, French infrared expert Jean-Claude Barré spotted a strange heat trace on the north side of the building, right at the place where four rafters hung in a V shape upside down on the steep corridor. down. When the pyramid was born about 4,500 years ago, these rafters were difficult to detect because they were hidden behind clad stones.

During the construction of the pyramid, the rafter does not serve a decorative purpose but to protect an empty cavity and prevent the ceiling from collapsing. The team has yet to find out why the ancient people used multiple rafters at the same time to protect a small area at the top of the corridor.

After mapping the region with 3D models, they decided to install three aluminum panels at the end of the corridor down to collect muon cosmic particles. This technology relies on continuous muons hitting the surface of the Earth. They emanate from the upper layer of the Earth's atmosphere, produced by collisions between cosmic rays in the galactic environment and atomic nuclei in the atmosphere.

Tayoubi and his colleagues placed highly sensitive pre-muon detectors, called emulsions, inside the pyramid to distinguish areas of dense and sparse particle density in the pyramid. When analyzing the film from detectors in Nagoya University, Japan, they found that the amount of muons was particularly high along one direction, indicating the hollow cavity like a corridor.

"The exact shape, size and position of this cavity are being studied further," the team said. They placed 12 new emulsions in the downward corridor and will collect data by the end of October, according to Tayoubi.

The findings were submitted to the scientific council by the former Minister of Antiquities Zahi Hawass. Zahi Hawass, argued that more research is needed before confirming the existence of an empty chamber or secret room. The Council approved the proposal for the ScanPyramids project to last another year.
