Yang Liwei heard the “knock on the door” in space, and the answer was revealed 17 years later, thanks to his wit at that time

In the book, human beings feel that they can challenge the trisomy because of their own progress. As a result, they are beaten to death by the simplest way. This sentence, combined with the wonderful scenes in the novel, can be described as a desperate lesson. In fact, it is the same in real life. Although human beings and nature are getting closer and closer in recent years, the closer we are to nature, the more we feel that human beings are small. Even though technology is so advanced, even Yuval herali thinks that human beings have become gods. In fact, the road of human development is still far away. In front of nature, we are still children, not to mention the Unknown Universe. < / P > < p > for this, astronauts who have been in space should feel more about it. Yang Liwei, for example, had his own experience. He had heard the sound of “knocking on the door” in space. So what happened then? According to current scientific exploration, the diameter of our universe is about 93 billion light-years, and the universe has evolved about 13.8 billion years since the big bang. Such a long time, such a huge scale, like a mountain in front of us, our technology and honor, really there is no place worthy of praise. < / P > < p > at present, the level of human science and technology can not reach 1% of the speed of light, and the universe is in the afterwave of the big bang and will continue to expand. To put it bluntly, the speed of human flight and exploration can not even keep pace with the expansion speed of the universe. The behavior of human beings who claim to be God is really exaggerated. However, human beings have one characteristic: Although the universe makes us despair, human desire never stops us from exploring. It took us less than 10000 years from monkey fishing for the moon to the present civilized society. Such rapid development also makes us confident in the future. Since the beginning of the last century, we have launched many spaceships to explore the unknown world. In July 1969, American astronauts even left their first footprints on the moon. However, the distance between man and the universe is still so far away. Not only that, the universe is also full of many unknown dangers, which will have a great impact on us at any time on the road of our exploration. Mr. Yang Liwei, a famous Chinese astronaut, was once in danger of the universe. At that time, he set foot on the journey of the universe with the blessing of all people. In this new environment, we Chinese people also have their own place, so all of us are jubilant on the earth. < / P > < p > but nobody thought of it, and then there was an accident. Mr. Yang Liwei actually heard a strange sound in the spaceship, which seemed to be “knocking on the door” and was ringing all the time. Listening to the sound of knocking at the door, Yang Liwei was naturally shocked. You know, in the cosmic environment, if someone knocks at the door, it’s either a ghost or an alien. However, fortunately, Mr. Yang Liwei is very resourceful. He starts the spaceship without saying a word and returns quickly. This incident also attracted many people’s attention at that time. Many people thought that this was an alien visit. Some even suggested that it might be related to some wonderful existence on the moon. < / P > < p > it is precisely because of this world that people begin to have more and more fantasies about space. For this unknown voice, there are different opinions, including fear, surprise and surprise. So what’s going on here? Because of the limited level of science and technology at that time, there was no answer, and people could leave a lot of speculation. However, after 17 years, scholars came forward to explain. In fact, the so-called knock on the door was not really visited by aliens, but that there was a problem with the spaceship at that time. In fact, the spacecraft itself was deformed due to temperature and pressure in the outer space environment. The sound of knocking at the door is actually the distortion of the aircraft itself. < / P > < p > it was not until then that we realized that it was not the aliens that caused the trouble, but the terrible outer space environment that had a great impact on it. At that time, Yang Liwei started the spaceship to return in time, otherwise, there might be great danger. < / P > < p > in fact, in addition to Mr. Yang Liwei, there are also astronauts in foreign countries who have suffered from this kind of thing. In 1970, a similar accident happened on Apollo 13, when the oxygen tank exploded. Unfortunately, the three astronauts escaped in time. However, it can be seen from this that the environment of the universe is not as simple as human beings think. Astronauts are dancing on steel wires when working in outer space, and there is a danger that is difficult to rescue all the time. In fact, from these cases, it will take us a long time to get out of the womb of mother earth and into the environment of the universe. At present, we have neither the ability to reach 1% of the speed of light, nor a strong ability to adapt to the universe. < / P > < p > and there is also a very important problem. According to the current international space expenditure data, more and more countries are not willing to invest large funds in space exploration, and even the giant United States has begun to be conservative. Therefore, Mr. Liu Cixin once had a feeling that human beings should not only focus on the front of their eyes, but should set their targets on the universe. < p > < p > he even proposed that it is better to search for new resources in the universe for environmental protection on earth, because the cost is similar. It can be seen from this that Mr. Liu Cixin actually yearns for the universe and worries about the stagnation of human beings towards the universe. Of course, there are worries and hopes. Although it may cost a lot to adapt to the environment of the universe in a human state. And in terms of the speed of human development, it will be very difficult to step into the universe until our entire civilization is destroyed. However, there are still many ways to solve this problem. At present, the physics community is studying the quantum world, the multi-dimensional world and even string theory. If breakthroughs can be made in these fields, the distance between us and the universe may be infinitely close. < / P > < p > in addition, some scientists have put forward ideas. In fact, there is another option for human beings in the future, that is, the research on robots. Because robots are much faster than humans. As Kevin Kelly said, technology is a new round of biology, it will fall from the human baby sitter’s arms, and we can no longer understand the development thereafter. < / P > < p > so we put our technical power into the research of robots, let their exponential explosion of wisdom develop to explore the universe, and let their bodies that can adapt to the environment can touch the unknown existence. Therefore, the world we live in is really wonderful. We should not confine our eyes to only one acre of land in front of us, but also look up at the stars. In the distant universe, there are black hole horizons that people can’t understand, the speed of light, and the legendary aliens. How does all this exist? Will these things be solved by us? We should explore in the future. What’s more, as the saying goes, when there are difficulties, there will be challenges and progress. Forest apes were forced to walk upright because of the scarcity of forests. Because the ancestors of Homo sapiens had no strong physique, they could only suck bone marrow and use tools. Because primitive humans could not cope with natural disasters, they began to domesticate wheat. Therefore, mankind is constantly in a desperate situation, out of a brilliant road, for the universe, we should maintain awe, but never despair. Privacy Policy
