Ancient Egypt, known as one of the four ancient countries in the world, ranks alongside ancient China, ancient Babylonia and ancient India. Ancient Egyptian civilization had a quite prosperous stage, and agriculture and commerce were the most brilliant countries in the world at the same time. The ancient Egyptian emperors were called pharaohs, who controlled everything in Egypt, while the domestic people tried their best to develop agriculture and animal husbandry and contributed to the prosperity of the empire.
The ancient Egyptians were superstitious. They have their own religious beliefs and believe that people can be reborn after death. Because of this, whenever a Pharaoh died, the priests in ancient Egypt would dehydrate his body and make it into what we know as a mummy, and the place where the mummy was stored was the pyramid.
The glory and fame of the ancient Egyptian pyramids need not be described in Bian Xiao. There are more than 80 pyramids in Egypt, all of which have become the wealth of mankind without exception. So far, there are still many mysteries lingering over the pyramids, the most striking of which is the mystery of the construction of the pyramids.
Let's take the largest pyramid in ancient Egypt as an example. It is called pyramid of khufu, with a height of146.5m and a bottom length of 230m. * * * It consists of 2.3 million boulders with an average weight of 2.5 tons. It is said that the huge stones used to build the pyramids are arranged so closely that even the gaps between the stones can't hold a knife.
Having said that, we have to admit the wisdom and advanced productivity of the ancient Egyptians, because modern architects insist that if we want to build such a huge pyramid according to modern productivity, we must use all kinds of large-scale mechanical equipment to assist, otherwise we can't complete this huge project.
Just when everyone was surprised by this, a different voice began to sound. Some archaeologists think that the building materials of ancient Egyptian pyramids are "tricky".
Several years ago, a group of archaeologists made a special trip to Egypt. With the consent of the local people, they collected a large number of samples of pyramid building materials and brought them back to China for scientific analysis. Under the microscope, they were surprised to find that there were obvious bubbles in the stone samples they brought back. However, in geological research, experts all know a simple truth, that is, natural rocks cannot have bubbles. Not only that, some powerful archaeologists also knead the huge stones of the pyramids with their hands. Surprisingly, these "stones" were crushed into pieces.
What other amazing discoveries will archaeologists make under the microscope? The answer is beyond everyone's expectation. In addition to many bubbles, there are many substances similar to powder and gravel in building materials. Through the spectral identification of the substances, they finally determined that these substances were lime powder and sand, which stuck around the adhesive in the form of fine particles. Therefore, experts infer that these stones used to build pyramids are obviously not natural stones, but artificial concrete substances.
The evidence does not stop there. Scientists even found a lot of "fiber materials" in these building materials. At first, archaeologists thought that the maker accidentally dropped it, but with further research, more and more fiber materials began to appear, even accounting for about 2% of the whole boulder. Hard evidence is in front of us. Fiber materials do not fall down unintentionally, but act as a partition between the mold and the soil when making concrete, and at the same time, they can also play a reinforcing role in concrete.
All along, all people in the industry believe that this huge project of the ancient Egyptian pyramids needs at least1-200,000 people to work at the same time 10 years. After all, the steps of collecting, polishing, transporting and stacking boulders are extremely complicated. However, after the experts found that the building material of the pyramid was concrete structure, they speculated that it only took 1500 people to work for half a year to "pour" a pyramid of the same size.
It is worth mentioning that the stone carvings in the pyramids of ancient Egypt also confirm this point. The reliefs in ancient Egypt are not only exquisite and gorgeous, but the most important thing is that all the carving contents are completed at one time, and there are almost no traces of alteration and reconstruction, which is completely unreasonable. It is important to know that any sculptor will make mistakes in his creation for various reasons, and it is difficult for ancient Egyptian craftsmen to avoid such a high probability event. The only explanation is that these reliefs are all cast at one time. When the concrete is wet, the sculptor can carve easily. Once there is any mistake, he can change it at will until the creator is satisfied.
For the above conclusions, many experts in archaeology also raised objections and produced a lot of evidence to try to refute them, which led to a considerable debate among them. However, in Bian Xiao's view, the more intense the debate, the closer it is to the truth. I believe that in the near future, archaeologists will definitely give us the most reasonable and closest explanation.
