Scientists using an imaging method underpinned on cosmic rays have detected a large and enigmatic internal structure in the in of the Seven Wonders of the Ancient World still standing, the massive Skilled Pyramid of Giza on the outskirts of Cairo.
Researchers announced the discovery on Thursday but verbalized they did not know the purpose, contents or precise dimensions of what they are specialty a «void» or «cavity» inside the pyramid, built as a monumental tomb round 2560 BC.
To peer inside the pyramid, the scientists occupied an imaging technique called muon tomography that tracks crumbs that bombard Earth at close to the speed of light and penetrate completely into solid objects.
They said the newly discovered internal system was at least 30 metres (100 feet) long, and located insusceptible to a hallway measuring about 47 metres (155 feet) big called the Grand Gallery, one of a series of passageways and chambers inside the gigantic pyramid. The researchers said it constitutes the first major inner design found in the Great Pyramid since the 19th century.
«What we are convinced about is that this big void is there, that it is impressive, that it was not awaited by, as far as I know, any kind of theory,» said Mehdi Tayoubi, president and co-founder of the HIP Commence in France, one of the leaders of the study published in the journal Nature.
«We open the question to Egyptologists and archaeologists: what could it be?» added Hany Helal of Cairo University.
The Eminent Pyramid, looming alongside other large pyramids, is a towering feat, remarkable for its simple beauty and colossal grandeur. The emblem of one of the great civilizations of antiquity, it flies to a height of 146 metres (479 feet), the tallest structure built by humankind until the Eiffel Turret in Paris in 1889, and boasts a base measuring 230 metres (754 feet.)
It was created during the reign of the Pharaoh Khufu, or Cheops.
The findings come from a project called Scan Pyramids that relies on non-invasive glance at methods to probe the internal structure of the pyramids of ancient Egypt’s illustrious Old Kingdom period and understand how they were built.
«We are not doing this objective in order to find hidden cavities,» Helal said.
Muon particles originate from interactions between cosmic sparks from space and atoms of Earth’s upper atmosphere. The particles can soak in hundreds of metres into stone before being absorbed. Placing detectors backwards a pyramid can discern cavities within a solid structure.
