Precision Engineering !
This colossal structure, the last of the seven ancient wonders and the largest stone building in the world, still provokes awe, controversy and a plethora of theories that inspire bitter debate to this day. Instead of going over the well-established mysteries, we would like to shine new light on this important enigma that appears out of place in ‘Stone Age’ Egypt.
The real challenge the Great Pyramid still poses to us in the opening decade of the Third Millennium is the physical plant itself. Theorists have gone on endlessly speculating about how it was built and the metaphysical, cultural and religious significance and/or symbolism behind its construction. Though several authors have offered tantalising possibilities, none have been conclusively proven.
The mystery remains unsolved.
To begin with, the massive size – the staggering volume and weight of the building blocks – remain problematic. With an estimated 2.3 million blocks with a weight of about 4 million tons, the pyramid is two-thirds the mass of the Hoover Dam. The sheer size and the numbers of blocks that had to be quarried and moved into place, presents numerous architectural, construction and engineering headaches.
These issues have been raised time and again, yet are still unsettled. It is time to move on and define the even more difficult issues. We consider the core ‘hard’ problems to be those that reflect precision engineering and assembly line manufacturing accomplished on a massive scale. The primitive tools scenario concocted by Egyptologists does not explain the following tasks:
-
Creating precision-cut casing blocks weighing 16 tons, fitted together and held by a super-glue mortar that maintained a tight seal forming a nearly seamless shell.
-
Leveling the 13-acre limestone bedrock base to a degree of accuracy only recently achieved with laser technology.
-
Squaring the base to True North with minimal deviation.
-
Excavating the ‘Descending Passage’ 350 feet into solid bedrock at a 26-degree angle while keeping the tunnel arrow-straight for its length.
-
Bringing the massive 48-story pyramid together around complex internal structures, retaining the true shape to enable the builders to form the apex. (These internal structures include four enigmatic ventilation shafts and a coffer in the King’s Chamber that is too large to have been moved through the opening. It shows evidence of having been cut with a jewel-tip saw.)
-
Extensive usage of different types of machined granite inside the Great Pyramid chambers.
The father of modern Egyptology, Sir Flinders Petrie, marvelled at the precision and size of the casing blocks. He carefully measure the blocks and found that “the mean thickness of the joints are .020 and therefore, the mean variation of the cutting of the stone from a straight line and from a true square, is but .01 on length of 75 inches up the face, an amount of accuracy equal to most modern opticians’ straight-edges of such a length.”
The modern international engineering firm of Daniel, Mann, Johnson & Menendhall conducted a forensic analysis of the Great Pyramid. Their findings are evaluated in an article published in Civil Engineering.
The pyramid was oriented with its major sides either north-south or east-west. This in itself was a remarkable undertaking, given the accuracy to which it was done, because the Egyptians had to perform the work using astronomical or solar observations – the compass had not yet been invented. The dimensions of the pyramid are extremely accurate and the site was levelled within a fraction of an inch over the entire base. This is comparable to the accuracy possible with modern construction methods and laser levelling.1
The summary speaks volumes between the lines. The problems with the Descending Passage are numerous. For starters the tunnel is less than 4 x 4 feet, enough for no more than one excavator wielding a hammer-stone at any given moment. How would our proposed digging crew negotiate the space in the suffocating darkness once they had dug down 50 feet and more? In addition how would the 26-degree angle be set and maintained without lights or levels? The lack of carbon deposits on walls and ceiling indicate that torches were not used.
Once again, Petrie measured the passage and found an amazing accuracy of .020 of an inch over 150 feet and a mere .250 inch over 350 feet of its constructed and excavated length. We submit that this passage with its smooth surfaces, squared shape, and accurate angle could not have been tunnelled with primitive tools and methods.
The Great Pyramid remains the world’s greatest wonder and ancient enigma. We suggest researchers should pay more attention to these details and ask about the materials used inside the Great Pyramid, especially near the ventilation shafts. We now have two doors blocking a very important shaft, the one that pointed to the star Sirius in 2450 BCE.
