Scientists discovered the cavity of the enormous inside the pyramid of Cheops in Egypt, to increase the opacity of the Pyramids of Giza.
It is not known why the presence of this cavity, or whether it has any value because it can't access it anymore, apparently.
He announced this discovery scientists, French, Japanese, after two years of study.
The scientists used imaging technology allow more muography, which can change the density within the combinations of huge rocks.
"A single structure or multiple structures"
Building the Great Pyramid, or pyramid of Cheops, during the reign of the Pharaoh khufu between 2509 و2483 BC.
It is considered the pyramid of Cheops, which has a height of 140 meters, the largest among the three pyramids in the pyramids at Giza.
The pyramid of Cheops, features a three-room spacious en suite, and a series of hallways, beautiful lobby, large with a length of 47 meters, and a height of 8 meters.
The lumen discovered recently is located above this lobby directly, and has the same dimensions.
And Mehdi LED from the Institute of H. A. B. in Paris: "we don't know whether this massive Cavitation horizontally or tilted. We don't know if it was made of a single structure or several structures in a row."
He added: "what we know for sure is that the presence of this cavity is huge, which is impressive, and it wasn't available before in any theory to my knowledge".
The team of professional scientific named survey of the pyramids or the "population pyramids" the very lack of description of the cavitation as"the room".
It contains the pyramid of Cheops on the room is small, experts believe that the masons, probably established to avoid his fall, through the alleviation of the pressure of the weight represented by the stones.
There are five of those rooms, for example, above the upper chamber to the king.
Headed by archaeologist famous American, Mark Linz, Committee retreat process the task of surveying the pyramids.
And Linz (used in the survey of the pyramids) accurate, but not yet convinced of the importance of the discovery.
Added Linz in statements to the BBC: "it may be some kind of void, left by the builders to protect the roof very thin Hall big from the pressure of the weight of the pyramid".
It is believed one of the leaders of the scientific team, which is Hany Helal from Cairo University, that the cavity is very large compared with the purpose of easing the pressure of weight, but he acknowledged that the experts will be arguing about it.
Helal said to the journalists: "what we do is try to understand the internal structure of the pyramids, how they built this pyramid".
He added: "egyptologists famous archaeologists, architects have some hypotheses. And what we do is to provide them with information, they are who should to tell us whether it is available or not."
