Since the discovery of the Tomb of Emperor Wen of Han in Bailuyuan, Shaanxi, there have been surprises in the excavation work for several consecutive days. It is worth mentioning that it is a bronze gear with extremely precise production technology, which looks no different from modern industrial gears, and the degree of fineness is also amazing to the experts present, thinking that its workmanship is comparable to modern technology.
Speaking of, from the perspective of time, this mysterious bronze gear has a history of more than 2,000 years, however, surprisingly, although it has been baptized by the years, it is placed in the modern era, leaving aside the bronze material, it is not inferior at all, and its appearance has also made many people think that this is a "black technology" from the Western Han Dynasty, and even some people doubt that it will not be left behind by the "crosser" production.
The origin of the mysterious bronze gear is a mystery, who made it?
The application of gear in industrial production began at the end of the 19th century, that is, after the Industrial Revolution, it was gradually used by people.
However, this does not mean that the concept of gears only appeared at the end of the 19th century, because according to historical records, as early as 2300 years ago, there was research on gears in the ancient Greek period, and more than 2150 years ago, the earliest gear models were also born in ancient Greece.
Therefore, it can be seen from here that the concept of gear has always existed, but the ancients used it less, and it has only begun to be widely used in the past 100 years.
From the perspective of time, during the Qin Dynasty in China, there were already bronze gears, and in the Eastern Han Dynasty, the production process and application of gears were more complex and common, for example, during the Jin Dynasty, gears have been used as the power system of water wheels for the use of stone grinding.
Therefore, although it is still impossible to confirm what this mysterious bronze gear found in the tomb of the Han Dynasty Emperor is for, its appearance is not as abrupt as we think, because it is also one of the tools that have been handed down from generation to generation, because human beings have used gears for more than 2,000 years.
Of course, compared with the bronze gears found by other archaeological discoveries, this bronze gear in the Tomb of the Han Dynasty looks more like a modern product, because many archaeologically found bronze gears are far less surprising than its workmanship, and they do not look so much like modern gears.
Therefore, some people will wonder whether there will be modern people who traveled to the Western Han Dynasty and then made this bronze gear during the Han Wendi period? After all, in the process of archaeological excavations, there are many cultural relics suspected of modern objects that have been excavated, making people wonder whether there will really be crossers in history.
So, will there really be "crossers" in history?
Let's take a look at what "mysterious cultural relics" suspected of being modern objects have been discovered by Chinese archaeologists over the years. First of all, in 1987, or in an archaeological excavation in Shaanxi, suddenly a pair of "high heels" made archaeologists shine, because although it was made of gold wire and wood, but the overall appearance was no different from the "high heels" worn by modern people.
Secondly, in history, Wang Mang, also from the Western Han Dynasty, also because of many advanced ideas before his death, as well as the invention of "black technology", in the process of archaeological excavations, it was suspected that he may be a "crosser".
Among all the "black technology" of Wang Mang, the most mysterious is the "vernier caliper", and the mysterious bronze gear that appeared in the tomb of the Han Wen Emperor this time, except for Wang Mang's vernier caliper, which is made of bronze, the others look exactly the same as the vernier caliper used by modern people.
Is this really a coincidence? This issue has also been discussed by many people for many years, of course, we can not find any evidence that Wang Mang is a "crosser", at the same time, it can not prove that in history, there are really "crossers", so all this can only be explained by "coincidence", after all, the wisdom of the ancients is unimaginable to us, although more than 2,000 years apart, but it does not mean that they are really inferior to us.
So, how likely is it that there really was a "crosser" in history? The answer is that there may or may not be, after all, our current level of science and technology is indeed inexplicable for some things.
Moreover, in the process of archaeology, it is not that there is no "evidence" left by any suspected "crossers", for example, in Qi County, Henan, there is a "ridiculous stele" that does not know who the owner of the tomb is, and on this tombstone, the words "nonsense" and "never come again" are engraved.
After decades of research, who this tombstone is, there is no answer, but also makes it more mysterious and confusing, there are views that perhaps this is the evidence left by the "crosser" in history, perhaps he crossed to the Ming Dynasty, his life was not satisfactory, so he will summarize this experience as a "ridiculous life", and said that he "will not come again", so what do you think about this?
