Mysterious hidden chamber corridor inside the Giza Pyramids in Egypt, Egypt is seen for the first time. Actually, scientists discovered the passage in 2016 but they didn't want to destroy the 4,500 year old relic to gain access to it.
So, a project was held to peek at the secrets that the cavity might have. Using endoscopic cameras and a technique called cosmic-ray muon radiography, experts were able to map the corridor for the first time and determine it was 9 meters long and 2.1 meters wide.
So what's the use? It is possible, as we quoted from the Daily Mail, that the structure was designed to help distribute the weight of the pyramid around the entrance or other spaces that have not yet been discovered.
This 146 m high Egyptian pyramid, built as a royal burial place around 2560 BC, is the only one of the Seven Wonders of the Ancient World still standing today.
The construction of the corridor is unfinished and can also add to the knowledge of how this pyramid was built. Research will continue to find out more about the hidden structures in the Pyramids.
"We will continue the scan so we will see what we can do to find what we can find under it, or at the end of this corridor," said Mostafa Waziri, head of the Supreme Council of Antiquities.
The five chambers above the king's burial chambers in other parts of the pyramid are also thought to have been built to redistribute the weight of the massive structure.
The corridor discovery was part of the Scan Pyramid project, which for the past seven years has used specialized technology including infrared thermography, 3D simulation and endoscopy to peer inside the structure. Despite being one of the oldest and largest monuments on Earth, there is no single consensus on how the Pyramids were built.
