Important Find in the Cheops Pyramid of Giza
A previously unknown chamber in the Cheops pyramid of Giza has been discovered by an international research team. As early as 2016 measurements had given reason to assume the existence of a hidden hollow space in the vicinity of the chevron blocks over the entrance. Now scientists from the Technical University of Munich (TUM) have used ultrasound and endoscopy to make an important contribution to confirming this assumption. The status of the Egyptian pyramid as one of the best-investigated structures in the world makes this find particularly important.

Standing at over 140 meters (460 FEET) tall, the Cheops pyramid is considered the largest and oldest of the pyramids of Giza. It is made of millions of limestone blocks, and it is believed to have taken more than 20 years to construct. As part of one of the Seven Wonders of the Ancient World, it has been thoroughly explored; however, the structure still holds many undiscovered secrets. TUM researchers have now solved one more of the pyramid’s mysteries.
As part of the international research team “ScanPyramids” the Munich scientists have proven the existence of an empty chamber which was until now only posited based on measurement data. The hollow space is located above the original entrance to the pyramid, which is not accessible to the public.
Assumption Confirmed
In 2016 several measurements by Japanese and French researchers provided evidence for the existence of the chamber. The TUM research group has been on board since 2019, helping to explore the pyramid for hidden structures. They use various non-destructive testing methods which make it possible to look into the stone blocks and the areas behind them. “The pyramids are a World Heritage Site. This means we have to be especially careful when conducting our investigations so that we don’t damage anything. We’re working on the Cheops pyramid with radar and ultrasound measuring devices that can be used on a non-destructive basis, and in part even contact-free,” says Prof. Christian Grosse, TUM Chair of Non-Destructive Testing.

Chamber is Larger Than Expected
The initial measuring devices provided a good first impression of the situation. The scientists then used endoscopy to confirm the assumption. The team found an opening between the stones of the chevron, a solid stone construction, through which they were able to run a tube into the chamber. They then used this tube as a guide for an endoscopic camera lens. The camera confirmed the existence of the hollow space. “Discovering a hollow space in a pyramid is already something special. But the fact that this chamber is large enough to accommodate several people, well, that makes the discovery even more important,” says Prof. Grosse.
The chamber is larger than researchers had assumed in the past. The original measured data pointed to the existence of a corridor at least five meters long; however, according to initial estimates, the length of the chamber considerably exceeds this length. There are no footprints or other evidence of human activity to be seen within the chamber. Thus the research group assumes that this room has not been seen by anyone for approximately the last 4,500 years.

New Chamber Calls for Further Research
Determining the former purpose of the newly discovered chamber and what is located behind the back wall of the room will require additional research. The confirmed findings highlight the need for further investigation of Egyptian pyramids and in particular the value of the new approach using a combination of various testing technologies and procedures.

What follows has been known since 2006 via university research, however only Pravda in Moscow published the article titled “The Documented Ancient Construction Method of The Great Pyramid”. Pravda placed the article on the London Global News Exchange in 2019 where it was ignored, or perhaps avoided.
Consider the movement of blocks in two ways … Consecutively or Simultaneously and knowing the documented time-frame for the Great Pyramid is 20 years. Logistics of Engineering can only accommodate the SIMULTANEOUS movement of blocks which absolutely rules out consecutive and thus rules out ALL ramp and water shaft-canal theories.
The method used is known today as Rack & Pinion Mechanical Technology and the Egyptians developed its prototype at Giza. Those hundreds of limestone steps you observe for all Giza Pyramids are RACKS, over all four sides and height.
Inty Shedu was the carpenter in chief at Giza and fabricated LOBES made from short planks of Cedar which had been imported from Lebanon as we know via the “Palermo Stone”. Evidence for the “four lobe pinion pulley” is the “Petrie rocker” excavated in 1895 by Edouard Neville and handed to Petrie in person for his London museum.
The Shedu four-lobe pinion-pulley is a machine of Class Two Lever Principle, Pivot-Load-Effort, same as a forward wheel, wheel-barrow, and has a mechanical advantage of 2.8 (MA=2.8) which means a 2500 kg Pyramid block can be raised with an input effort of 900 kg. Search haitheory
The engineering logistics of CONSECUTIVE traffic of blocks raised within the documented twenty year time-frame rules out ALL ramp and water-shaft canal theories which all have “one block follows another’ illogical approach. Blocks were moved SIMULTANEOUSLY over all those STEPS you see of all Giza Pyramids. Four-lobe pinion-pulleys were used on and over ALL available horizontal STEP surface area. Hoist one block per hour over an eight hour day. Forty pulleys, ten per side, raise 320 blocks.
Over a year, 365 days 116,800 blocks are raised. Over Twenty years 2,336,000 blocks have been raised. The method is known in our modern world as Rack and Pinion mechanical engineering. Those hundreds of limestone STEPS can be termed RACKS. The Pinions were fabricated from imported Lebanese Cedar timber under the supervision of Chief Carpenter Inty Shedu who was entombed on the Giza Plateau. Inty Shedu’s four tomb statues are exhibited in the Cairo museum. The Shedu Four-Lobe Pinion-Pulley has an innate mechanical advantage of 2.8 (MA=2.8) which means a 2500kg Pyramid block is raised with an input effort of 900kg.
