With the help of cosmic rays, they made a great discovery in the pyramid of Giza.

An incredible discovery was made in Great Pyramid of Gizait is a hidden corridor designed to lighten the weight of the structure.

An international research team used cosmic ray imaging to analyze a cavity behind the northern wall of the pyramid, which was first discovered in 2016. Their results were announced at a press conference with Egyptian officials held outside the 456-foot pyramid. pyramid on Thursday.

“This discovery is, in my opinion, the most important discovery of the 21st century,” Zahi Hawass, Egypt’s former antiquities minister, told NBC News Thursday.

The passage-like space is about 2 meters wide and 9 meters long and was built as royal burial chambers around 2560 BC.

The corridor “protected or relieved pressure on something below it,” said Mostafa Waziri, general secretary of Egypt’s Supreme Council of Antiquities. He added that it could be or something else, but they would resolve it “very soon”.

The pyramid, also known as the Pyramid of Khufu, was built on the Giza Plateau outside Cairo by Pharaoh Khufu, a 4th dynasty pharaoh who ruled from 2509 to 2483 BC.

“Today’s discovery tells us that something important will soon be discovered under this tunnel, which may be Khufu’s real burial chamber,” Hawass said.

Cosmic ray technology tracks muon particles (electrically charged particles with a mass greater than the mass of an electron, so their decay must produce an electron plus other particles whose total electrical charge is zero) that bombard the Earth at a speed close to the speed of light. and penetrate solid objects more efficiently than x-rays, allowing scientists to accurately visualize the presence of unknown structures in them.
