Why does the Egyptian proverb say that "man is afraid of time, and time is afraid of pyramids"?

There is no doubt that the pyramids have become synonymous with Egypt. You don't know that Egypt has the Nile, temples and the Red Sea, but everyone knows that Egypt has pyramids! Because of the 5000-year-old veil, because it stands tall and incredible, and because there are too many amazing digital mysteries, the mysterious coat of the pyramid has never fallen off. It is said that time can change everything, but there is an Egyptian proverb: "People are afraid of time, and time is afraid of pyramids."

There are more than 100 pyramids in Egypt, the most famous of which is the "Giza Pyramid" located in the north of Memphis, the capital of ancient Egypt, and now southwest of Cairo, the capital of Egypt. The pyramids of Giza are not a single pyramid, but a group. It is the tallest building in ancient Egypt.

There are 65,438+00 pyramids in the pyramids of Giza. The three largest and best-preserved pyramids were built from 2600 BC to 2500 BC by the three emperors of the Fourth Dynasty, namely pyramid of khufu, Havla Pyramid and Menkoala Pyramid, which is what we often call the Great Pyramid now. There are many "Mastaba" (Arabic for bench) and small golden pagodas around the three great pyramids.

Pyramid of khufu is the largest pyramid in Giza and the largest of all Egyptian pyramids. It is listed as "the first of the seven ancient wonders of the world" and the only one that has stood the test for more than 4,000 years. This is why the Egyptians dare to say, "Man is afraid of time, and time is afraid of pyramids."

The original height of pyramid of khufu is 146.4m, which is equivalent to a 40-story skyscraper. Due to years of weathering, the top has peeled off 10m, and now it is 137m high. The bottom of the tower is square, each tower is 230.6 meters long and covers an area of 5.3 hectares. The whole pyramid consists of 2.3 million stones, with stones of different sizes weighing from 1.5 tons to 160 tons, and the total weight of the tower is about 6.84 million tons. Some researchers who love the pyramids calculate that if the stones of the pyramids are transported by train, 600 thousand wagons are needed; If these stones are cut into small pieces averaging one cubic foot, they can circle the earth along the equator.

The four inclined planes of pyramid of khufu face east, south, west and north respectively, and each plane is almost an equilateral triangle with an inclination of 5 1.52 minutes. Researchers found that back to 2500 BC, four tunnels pointed to four special stars crossing the meridian at that time, namely the second star in Ursa minor, the brightest first star in Canis major, Sirius, Polaris and the first star in Ursa major.

There is also an Englishman, Ferrand Qi Petrie, who is crazy about the pyramids. He took his father to survey pyramid of khufu for 20 years and was surprised to find many magical figures: the height of the pyramid multiplied by 65.438+0 billion equals the distance from the earth to the sun (65.438+0.5 billion kilometers); The weight of the pyramid multiplied by the power of 10 equals the weight of the earth; The circumference of the bottom of the pyramid divided by the height of the tower multiplied by 2 equals π, and so on. It seems that all the history and future of nature are hidden here.
