# The mystery of the Great Pyramid

Of course, the mainstream scientific community has always sneered at such metaphysics in the cloak of science.
In the 5th century BC, Herodotus, an ancient Greek historian who visited the Giza Highlands, wrote about his perception of the Great Pyramid. In his book “History”, he said: “King Khufu obeyed the suggestions of the priests, and made the people in dire straits. He forced the people of Egypt to work for himself, and more often than 100,000 people every three. The labor service is performed alternately once a month. Just building the roads that drag the stones makes the people’s labor lasting 10 years. It takes 20 years to build a pyramid.” The book also records the construction method of the Great Pyramid: “Their The construction method is a stepped construction method. First build the stairs, and then use the wooden crane to lift the remaining stones. Perhaps as many cranes as the number of stairs are used, or perhaps only one crane that is easy to move,—— The ground moves up.” However, Herodotus was born more than two thousand years after the completion of the pyramid construction. His description may not be accurate.
From 1880 to 1882, Sir Flinders Petrie, the father of modern architecture and a British Egyptologist, made accurate measurements of the Great Pyramid for the first time. The measurement results were published in his book “The Pyramids and Temples of Giza” in. Petri believes that the most amazing thing about the Great Pyramid is its orientation-the four sides of the base face the four directions east, west, south and north extremely accurately. In addition, the accuracy of the construction process of the Great Pyramid is also amazing. For example, the average length error of the four sides of its base is only 58 mm. The base is flat and almost exactly the same as the horizontal line. The positions of the four sides of the base are very close to the four positions of the compass based on true north (non-geomagnetic north), and the errors are all within 5 minutes. (1 minute is 1/60 of 1 degree), the average angular error of the base square is only 12 arc seconds.
According to Petri’s investigation and some follow-up research results, some people pointed out that the original height of the Great Pyramid was 280 cubits, the length of each side of the base was 440 cubits, and the ratio of the circumference of the base to the height of the Great Pyramid was 1760/280. , And 2π (π is the circumference of the circle, approximately equal to 3.14 or 22/7) less than 0.05% difference. This is the so-called “mystery of π”.
As a matter of fact, regarding the “mystery of π”, although various words have different expressions, the roots are traced to the work “Car of the Gods” by the Swiss von Daniken. The book states: “The area of ​​the base of this pyramid divided by twice the height of the tower is exactly the famous pi ratio π=3.14159. Is this a coincidence?” In this regard, an archaeologist pointed out that the ancient The Egyptians had mastered the pi ratio in the practice of measuring land (but it was not expressed as a decimal value at the time, but a fraction, approximately equal to 3.16), so the so-called “mystery of π” does not hold.
The precision of the construction of the Great Pyramid has to be impressive. Petri once exclaimed: The construction of the big golden letters: the placement accuracy of the stones of the tower is “comparable to what can be accomplished by today’s optical instrument manufacturing technicians.”
According to historical records, when the Great Pyramid was first built, the surface was covered with a layer of white cladding-flat top, inclined surface, and polished white limestone. There were about 115,000 pieces, all of which were carefully cut, with 5 palms. Ruler (an ancient unit of measurement, one palm ruler with a palm width of 3 to 4 inches or a length of 7 to 9 inches) accurately defines the slope of the slope. Below this layer of cladding is the stepped core structure of the Great Pyramid seen today.
In 1300 AD, a major earthquake shook many of the outer stones of the Great Pyramid. By 1356, the Egyptian ruler at the time ordered the stones to be transported away and used to build temples and fortresses near Cairo. To this day, some clad stones can still be seen near the base of the Great Pyramid, and the cutting process and accuracy they reflect is exactly the same as described by Petri et al.
Where did the stone used in the Great Pyramid come from? There are multiple theories that often contradict each other. Some scholars believe that the limestone blocks used in the construction of the Great Pyramid were polished with a kind of “limestone concrete” at the construction site of the Great Pyramid. This theory has been refuted by most Egyptologists, who believe that these stones mainly came from the quarry near the site where the Great Pyramid was built, and the outer layer of stone was transported through the river. Scholars have different opinions as to whether these stones were dragged into place, lifted into place, or rolled into place.
Who built the Great Pyramid? On this issue, the ancient Greeks believed that slaves were used in the construction of the Great Pyramid; while modern Egyptologists believe that the Great Pyramid was built by at least 100,000 male skilled workers.

The internal structure of the mystery of the Great Pyramid
of today’s tourists not to enter through the original entrance inside the Great Pyramid, but in AD 820 by a year to get through the channel, insert it straight in the Great Pyramid tower nearly 27 meters. The original population of the Great Pyramid is located 17 meters above the ground vertically and 7.29 meters west of the central axis of the pyramid. Going in from the entrance, there is a descent passage 0.96 meters high and 1.04 meters wide. After descending 109.23 meters at an angle of 26°31′623″, it becomes a horizontal passage, which extends 8.84 meters forward to reach the underground tomb. For some reason, the crypt was not completed. Because a pit was discovered on the ground of the crypt, some Egyptologists speculated that in the original design, the crypt was the real tomb, but Pharaoh Khufu later changed his mind—— He wants to bury himself at a higher position in the Great Pyramid.
At the top of the descending channel, there is a square hole, and the opening is blocked by a stone slab. This is where the ascending channel begins. The ascending channel is 39.3 meters long, with height and width and descending channel. Similarly, the angle of ascent is almost the same as that of the descending channel. The
ascending channel leads directly to the large corridor. There is a hole in the wall at the bottom of the large corridor, which is the population of a vertical shaft. This vertical shaft follows an irregular path and ends up with the descending channel Connected. There is a horizontal passage on the wall at the bottom of the Great Corridor, which leads directly to the Queen’s Tomb. The
Queen’s Tomb is located between the north and the south of the Great Pyramid. It is 5.75 meters long from north to south and 5.23 meters wide from west to east. The top is a spire, and the highest point is 6.23 meters above the ground. At the east end of the queen’s tomb, there is a 4.67 meters high alcove. Its initial depth was 1.04 meters, but it was later deepened, and it is speculated that it may have been the work of tomb robbers.
There are shafts on the north and south walls of the Queen’s Tomb, but these shafts are neither connected to the Queen’s Tomb nor to the outer wall of the Great Pyramid. There is no answer as to their purpose. In 1992, German engineer Rudolf Gunterbrenck used a crawling robot of his own design to probe a shaft in the queen’s tomb, and found that the shaft was blocked by a stone door. A few years later, the National Geographic Society designed a similar robot. It drilled a small hole in the south door of the queen’s tomb and found that there was a larger door behind it.
Some stone slabs were placed at the top of the large corridor. The angle of the slates was slightly inclined, and each piece was embedded in a slot, like the teeth of a ratchet. The purpose of this was to make each stone supported by the walls of the large corridor. It is not directly pressed on the rocks below, which prevents the total pressure at the bottom of the large corridor from exceeding the critical value. The ancient Egyptians were so ingenious to think of this.
