Scientists discover hidden chamber in Egypt’s Great Pyramid

 

 

In an article published in the journal Nature on November 2 n d 2017 , an international team said the 30-meter (yard) void deep within the pyramid is situated above the structure's Grand Gallery, and has a similar cross-section.

 

"This is a premier," said Mehdi Tayoubi, a co-founder of the ScanPyramids project and president of the Heritage Innovation Preservation Institute. "It could be composed of one or several structures... maybe it could be another Grand Gallery. It could be a chamber, it could be a lot of things."

The scientists made the discovery using cosmic-ray imaging, recording the behavior of subatomic particles called muons that penetrate the rock similar to X-rays, only much deeper. Their paper was peer-reviewed before appearing in Nature, an international, interdisciplinary journal of science.

 

 

The pyramid is also known as Khufu's Pyramid for its builder, a 4th Dynasty pharaoh who reigned from 2509 to 2483 B.C. Visitors to the pyramid, on the outskirts of Cairo, can walk, hunched over, up a long tunnel to reach the Grand Gallery. The space announced by the scanning team does not appear to be connected to any known internal passages.

Scientists involved in the scanning called the find a "breakthrough" that highlighted the usefulness of modern particle physics in archaeology.

"It was hidden, I think, since the construction of the pyramid," Tayoubi added.

The Great Pyramid, the last surviving wonder of the ancient world, has captivated visitors since it was built as a royal burial chamber some 4,500 years ago.

Experts are still divided over how it and other pyramids were constructed, so even relatively minor discoveries generate great interest.

 

The muon scan is accomplished by planting special plates inside and around the pyramid to collect data on the particles, which rain down from the earth's atmosphere. They pass through empty spaces but can be absorbed or deflected by harder surfaces, allowing scientists to study their trajectories and discern what is stone and what is not. Several plates were used to triangulate the void discovered in the Great Pyramid.

While the technology can detect large open spaces, it cannot discern what is inside, so it's not known if the empty space contains any objects. Tayoubi said the team plans to work with others to come up with hypotheses about the area.

"The good news is that the void is there, and it's very big," he said.
