There is an Arab proverb about this world's oldest construction, 'Man fears time, and time fears the pyramid'. Research is still going on to find out what kind of glue can hold the monstrous stones together for thousands of years. Years of research have revealed almost nothing about it.
The unknown wonder of the pyramids
The Mysterious Pyramid
Pyramids have always given people a touch of mystery. The excellence of technology in this ancient structure still amazes people. Day by day, as its secrets are revealed, more people are caught in its web of mystery. The Pyramids of Giza in Egypt are one of the ancient seven wonders of the world. It is sometimes called the Pyramid of Khufu or  the Pyramid of Cheops. There are two tombs in the Giza pyramid complex in honor of Pharaoh Khufu. Of the two tombs, one is by the Nile and the other is adjacent to the pyramid.

The three small pyramids built over the tombs of Khufu's wives and the Mastaba are known as burial places for the lower classes. In 1877, Joseph Sage made a remarkable discovery. He found that the Pyramids of Giza lie at the intersection of the longest line of latitude and longitude. Which means that the Pyramid of Giza is located in the center of the Earth's plane.
Construction style
The Pyramids of Giza in Egypt were built 4500 years ago. Until the 19th century, the pyramids were considered the tallest man-made structures. For 3800 years it has been proudly standing as the tallest structure in the world. Until now, the architecture, construction methods and skills of the ancient Egyptians to build something as grand as the pyramids are still awe-inspiring. There are also many pyramids scattered around the world.
More than 5,000 pyramids still survive as a wonderful example of the world's ancient architecture. However, the actual reason for the construction of the pyramids remains unknown. Experts differ on the question of why the pyramids were built. In many cases, stones weighing more than 10 tons were used during the construction of the pyramids. Pyramids are made by arranging huge stones in layers one after another.
How these heavy stones were lifted so high without any advanced machinery is still a wonder to this day. Researchers are still researching this unprecedented mechanism. Inside the pyramid is a network of narrow streets. Each chamber and narrow passage is connected to each other. These narrow tunnels are shining witnesses of thousands of years of ancient traditions and artifacts. However, the Egyptian authorities have excavated many things from inside the pyramids.

Therefore, many details of ancient traditions are not open to the general public.
Imhotep is famous as the inventor of the pyramids. He was a physician, an astronomer, a cleric at the time. His image is found inside the pyramid. Inside the main chamber of the Pyramid of Giza is a large Ark . It is almost impossible to carry this Ark along the narrow passage in the main room. This suggests that the pyramid was built around the main Ark . The pyramid was built facing north-south.
This north-south value was determined keeping in mind the alignment of the stars in the Saptarshimandala. During the construction of the tomb, it was found that it was tilted by 0.05 degree from North-South. It is amazing how accurately such fine measurements could be made with such great skill in those days without complicated equipment.
There is an Arab proverb about this world's oldest construction, 'Man fears time, and time fears the pyramid'. Research is still going on to find out what kind of glue can hold the monstrous stones together for thousands of years. Years of research have revealed almost nothing about it.
Hieroglyphics can be seen in every pyramid. Researchers have not found hieroglyphics in the pyramids at Giza. Hieroglyphics were later found in 2011 with the help of robots from a secret chamber inside the pyramid. The hieroglyphics found in the pyramids are believed to be the world's oldest written religious texts. This script is also the main source of the funerary literature of the Egyptian civilization.

In particular, the Saqqara Pyramid (built 2613-2181 BC) has the greatest number of inscriptions on its face and on the sarcophagi inside it. This script was originally carved for a dead pharaoh. A variety of mantras for funeral and post-funeral use are mentioned there. They believed that by chanting this mantra, the soul of the pharaoh would leave this world and reach the next world.
In addition, these inscriptions provide basic information about the life of a pharaoh. In Egyptian civilization, the role or character of a pharaoh in the state, society and religion is clearly stated. Apart from this, various deities are named and their role in the attainment of the soul is mentioned. More than two hundred gods and goddesses are mentioned in this script. As well as major and famous deities such as Osiris or Isis, there are also lesser-known deities such as Nekbet or Beis.
This script does not contain the entire Egyptian mythology. There are only descriptions of various important events in Purana. Somewhere the god of knowledge Thoth is shown inventing the script, somewhere the god of war Horus comes down to help the pharaoh. There are even references to the conflict and battle of the two rival gods, Horus and Set. Experts first learned the name of Osiris, king of the dead, from this pyramid script. In ancient Egyptian belief Ra, Osiris, Isis, Horus, Set, Nephthys and Thoth were the gods of fate.
The three pyramids of Giza were built in alignment with the Orion . If one looks at the sky with the tops of the three pyramids in the same straight line, then one will see Orion in that line. The walls of the Egyptian pyramids were covered with polished limestone during construction. As soon as the first sunlight fell on the pyramid after sunrise, it would glow. From afar, a pyramid was radiating the light of diamonds.
At first it may seem that the pyramid has four sides. But the Pyramid of Giza has eight sides . Each edge meets the top. In 1940, a pilot P. Groves first noticed these eight side while flying over Egypt. It can only be seen in the right light.
Worker
It is believed that slaves were used to build the pyramids. But a Harvard University study revealed that workers were hired to build the pyramids in exchange for wages. Workers from the north and south of the world were highly respected at that time as they were involved in the construction of great structures like the pyramids. This information was uncovered in 2010 by finding a tomb of pyramid workers. The bodies of the workers were preserved in the sand.
Interestingly, beer and bread were given with their bodies for the afterlife. The exact number of workers employed in the construction of each pyramid is not yet known. There is also disagreement about how many men it took to move the heavy pieces of stone. But historians believe that it took about 60,000 people to build the outer main structure and 30,000 people to build the inner structure. Most of the pyramids were built around the same time. The construction of the Pyramids of Giza took a total of 23 years.
The world's first air conditioning system
In the desert, the temperature difference between morning and night is very high. It gets hot during the day and cold at night. It is known that the temperature inside the pyramids was always constant at 20 degrees Celsius. At that time, this natural system of air conditioning still amazes people.
A special door
A special type of revolving door is seen in the pyramid. One part of which rotates but the other does not. There are a total of three such gates in the Pyramids of Giza. One of those doors weighs about 20 tons. The doors were so well made that the huge doors could be opened with one hand. If this door is closed, no one from outside will know that there is a door. If you don't know anything about it beforehand, everyone will have the illusion that there is a wall.
Flat roofed pyramid
Not only are pyramids with sharp tops, but some pyramids in Egypt also have a flat surface at the top. Many early pyramids were built with this flat top. 4700 years ago, the first pyramid was built by the Egyptians. The idea of ​​building a triangular pyramid was not common among the Egyptians at that time. This flat roof is found in the tomb of the Egyptian emperor Djoser.
According to archaeologists, the roof of the first pyramid was flat. A different type of architecture was used to construct the tombs of the lower ranks inside the pyramids. whose name is Mastaba. Historians believe that these mastabas were built so that these low-ranking people could serve the king in the afterlife.
Weight
The weight of Khufu's pyramid is 57 lakh 50 thousand tons. Where the weight of Burj Khalifa is 500,000 tons inside the current high-rise building. The pyramids are believed to have been built from 2.3 million massive blocks of stone. Where each stone piece weighs about 2.5 tons. In the 12th century, Saladin's son and Kurdish ruler King Al Aziz planned to destroy the pyramids.
He launched an attack against Menkori Pyramid. But he failed in this massive architectural destruction. Perhaps it was the great combination of weight and architecture that prevented this destruction against the pyramids.
Keeper of the Pyramids
4500 years ago, a giant Sphinx statue was built next to the pyramid. His portrait is made with the body of a lion and the face of a sphinx after the face of Pharaoh Khafra. According to the beliefs of the time, the statue of the Sphinx was built to guard the pyramids. The 241-foot-long Sphinx facing the sun still stands guard over the pyramid.
Gold provided
Ancient Egyptians believed that Egypt was the best place on earth for humans to live. After death they will live in a place like Egypt. But there will be no suffering in the life after death. Along with the dead body they used to give all the necessities of life. When a king died, gold was also given with him. Later in the rescue operation, the Egyptian authorities were able to recover and preserve most of this gold.
Sun clock's
Among the types of Sunclock's that have been discovered so far, the pyramid is particularly significant. When the sun is in the midheaven, no shadow is cast on the pyramids of Giza.
