Yang Liwei was the first astronaut in China to enter space. According to recollections, during his mission, he heard the sound of "knocking on the window" in space. To know that there is no airborne sound in space, what is the sound that Yang Liwei heard?
As we all know, the development of China's space industry is much later than that of the West. Even so, it has not stopped our country from improving itself. At first, China wanted to seek Western cooperation, but the other side was not happy, and even the International Space Station project deliberately excluded our country. That being the case, our country has achieved a breakthrough by relying on its own strength. Finally, in 2003, Shenzhou 5 successfully lifted off, and Yang Liwei became the first hero of China's entry into space. But the hero is not so good, before entering space, Yang Liwei has undergone day-to-day training. As the first person to eat crabs, the psychological burden is also very large, and if this task fails, it means that he will die for it.
Yang Liwei paid too much when he carried out his tasks
It was learned that after Yang Liwei successfully returned to Earth, some media photographed the corners of his mouth with blood stains. Yang Liwei recalled that when he was on a mission, he said that he had experienced a very difficult 26 seconds and almost thought he was going to pass. The 26 seconds mentioned here are the violent vibrations during the launch process, and Yang Liwei feels that his internal organs are about to be shattered. In this way, the blood stains on the corners of his mouth should have been left at this time.
Are there really aliens?
In addition to this dangerous process, Yang Liwei also said that when he was in space, he vaguely heard the sound of "knocking on the window". As we all know, sound travels with air, but this condition is not available in space, where does this sound come from? Did Yang Liwei encounter aliens?
The truth is revealed
Since the early technology was not enough to explain this problem, but with the continuous advancement of science and technology, the mystery was finally solved many years later. It turned out that after the spacecraft entered space, it would feel the air pressure, which would cause certain changes in the internal organization, resulting in a sound. It is also in this way that it is fortunate that Yang Liwei did not stay at that time, but returned to the earth.
China's space industry continues to develop, so far, there have been a number of astronauts successfully lifted off to carry out missions. Not long ago, China sent three astronauts into space again, this time to carry out a space station mission for half a year. Once China wanted to join the International Space Station, but it was resisted by the West. Now that China has its own space station, it has finally raised its eyebrows.
It is reported that a large number of countries have come to seek cooperation, and the United States is also among them. However, among the first batch of cooperative countries officially announced by Our country, the United States did not mention the United States, because the United States originally made harsh remarks and refused to cooperate with China in the field of space. Nowadays, seeing that China has achieved something, I want to cooperate, and there are such good things.
Facts have proved that whether it is international status or influence, it must rely on real strength to obtain. China has won the recognition of the international community with its strength time and again, and it is no wonder that even the West is afraid of China's rapid development. However, China will definitely not stop here, and must continue to improve itself, because the whole world is progressing, and once it relaxes, it will fall behind. At the same time, China has also said that our goal is to break through ourselves, and we definitely do not want to dominate the world, nor do we mean to compete with any country.
