Liu Weichang chatted with Gu Sileng in the office for a while, and got to know Gu Sileng's basic academic situation. After reading his information, he felt very satisfied. He said to Gu Sileng: "It has been a long time since you left school. During this period, the school's knowledge has not kept up with the progress of the times. During the period when you participated in the war against Japan, the international knowledge about space The knowledge of exploration has gone through two iterations. But that's not the most important thing. You can now take the master's course, write a thesis, and then you can follow me directly in the PhD. Mine is studying deep space Astrophysics also has a lot of overlap with your deep space exploration. Let’s think about it. When we met, we had seen the starry sky on the prairie of Inner Mongolia. Can you still recall it now?" Gu Si Leng smiled and said: "I will remember that picture from my childhood all my life. Good. On the beautiful prairie, the Milky Way slid down from the sky like a ribbon. The whole place was filled with bright stars, and the light of the moon seemed to be absent. So dazzling." Liu Weichang said with a smile: "Yes, your hometown is indeed a good place for stargazing. Did we also talk about the Nezha deep space probe at that time?" Gu Sileng thought about it and said: "Yes. .I remember you also talked about Proxima Centauri.”
Liu Weichang smiled and said: "It's indeed good. Our current Department of Astronomy at Peking University is building a huge space image experimental station observed by humans. In this image, you can find any galaxy, any nebula and any nebula observed by humans. Planets and stars." Guzman said: "Isn't the data very huge?" Liu Weichang. He nodded and said: "This is not a separate scientific research project of our country. It is shared with all countries in the world. Its name is Star Curtain. It has observed all galaxies within more than 20 billion light-years of the farthest reaches of mankind. That is to say, through this mirror galaxy, you can find any galaxy within 20 billion light years in the universe." Gu Sileng said in surprise: "It is so grand that it will take a lifetime to complete it." Liu Weichang said: "I am just one of these scientists. There are hundreds of thousands of scientists and thousands of scientific research institutions around the world working closely together to conduct deep space exploration. They have the Hubble Telescope more than two hundred years ago, as well as various current There are hundreds of different deep space probes launched by the country. They have never stopped in the universe. Now you can understand what the brilliance of the galaxy is. Behind every brilliance of the galaxy is the cosmic people who are not stopping. The dedication and sweat of labor." Gu Sileng nodded and said: "I will complete the tasks you assigned me in advance on time, and then join this huge event. Discover our own new planet?"
Liu Weichang said to Gu Sileng: "I can understand your mood, but academic work still needs to be done in a down-to-earth manner. Now I have more than 20 papers on hand. You can take a look first to see what you have learned and strengthen your basic courses. Then we will conduct research on space exploration." Gu Sileng replied seriously: "Okay. Mr. Professor, I will definitely complete the task you gave me." Then, Gu Sileng took over More than twenty papers handed over by Liu Weichang. These papers add up. There is a thick book, so thick. Gu Sileng took him over easily and gave Liu Weichang a military salute. Liu Weichang nodded, waved his hand and said, "Go down." Gu Sileng took the information and walked out of the office. Report to the department. I found a teacher to teach me. He started studying in the Astronomy Department of Peking University. Studying may have been easy for Gu Sileng. His results have always been excellent. Even at the National University of Defense Technology, he had never missed the courses on weapons and equipment manipulation and weapons and equipment maintenance.
This kind of theoretical study is even more familiar. But when he read the paper Liu Weichang gave him, he encountered unexpected difficulties. In imagination, a paper about deep space exploration and astrophysics should be as interesting and vivid as a science fiction novel or science fiction movie. In reality, academic papers are boring and murky. Gu Sileng spent a long time on his first academic paper. It took him almost a month to fully understand it, and he kept going to the library to look up information. It took me one and a half months to get a rough understanding of this paper. This is not just space observation, but also practical means. A lot of new technologies are used in it. like. Quantum computing. Physics research is all there, involving more than a dozen disciplines. Gu Sileng had to learn from scratch one by one, make up for every shortcoming, and then make his first bucket, hoping to fill it with a bucket of water. This takes a lot of time and effort. Quantum computing was not something Gu Sileng studied, and he didn't even know anything about it. He had to find courses and videos. Study from above. As Professor Liu Weichang said, we must lay a solid foundation step by step. Maybe it will be a good help in future study and research. If you are too ambitious, in the end all your research will be like a castle in the air, and the house in the desert will fall down as soon as you push it.
Studying was very busy, and Gu Sileng dove right in. During this period, he had no contact with Zhu Feng or Wu Jingquan. What pleased him most, however, was that every once in a while Natasha would expect a call from her. One day, after a busy study, Gu Sileng returned to his dormitory, took a bath, put on comfortable pajamas, and listened to some light music. At this time, Natasha called. Natasha said on the phone: "You have come to Beijing from Ningbo, and you are closer to us. When will you come to St. Petersburg?" Natasha said angrily on the phone. Gu Sileng said: "Studying is very intense. I didn't study directly. There are many courses that I have never learned before. I don't know many methods and learning methods. It takes a lot of time." Gu Sileng said . Natasha continued on the phone: "I don't care, I have been waiting for you for a long time. We can't always be like this, not seeing each other for a year. In that case, how can I live with the man I love? Hurry up. Come to St. Petersburg. The summer in St. Petersburg is very beautiful, not cold at all. All kinds of flowers are blooming like brocade. There are tall trees here, which are hundreds of years old. And the palaces in St. Petersburg are not at all It’s no worse than the Kremlin. Isn’t this enough to teach you? Then I’m here, think about it, it’s been a long time since you touched me.”
Gu Sileng felt excited when he heard Natasha's words. Indeed, after the war against Japan and a series of events, he had not even thought about touching a woman. It seems that since I separated from Natasha, I haven't touched a woman for a year or two. Only then did I realize that this was a very serious problem. Gu Sileng gritted his teeth and said: "Please bear with it a little longer, Natasha. I have to do a solid job in the work at hand. If there are staged results, I want to apply to St. Petersburg University. As visiting scholars, at that time we Then we can be together. By the way, we will get married without any problems." Natasha said dissatisfied: "You are trying to draw a pie for me again. It's always like this, I don't care, you must go to St. Petersburg within a year Come to me, or I will treat you badly." Go. Gu Sileng said: "Why are you so rude? Aren't we two very good friends?" Natasha said angrily: "Come here within a year, or I will find another man. You are making me grow old. In your tree?" After saying that, he hung up the phone angrily. Gu Sileng had no choice but to smile bitterly. Still turning around and attacking his own study.
Gu Silangyue was immersed in the study of astronomy. The more I respect the ancient Chinese people. Especially China's greatest astronomers Shi Shen and Gan De. They were all from the Spring and Autumn Period and Warring States Period in China. people. They didn't have computers back then. There are no astronomical telescopes. Actually using their method. The positions of 121 stars were found. Discovered the retrograde motion of Venus and Mars. Galileo and Copernicus more than 2,000 years later. Or based on the star map they drew. Europa 2 has been found in the solar system. All these achievements are beyond doubt the existence of God. Gu Sileng is one of the great astronomers in China. I felt ecstatic. He was very curious about how the orientation, longitude and latitude of those stars were calculated. I had never heard of it at that time. calculus. However, the reality is that they were accurately calculated. That all happened during the Spring and Autumn Period and the Warring States Period. You can't imagine achieving such results. It happened in BC. For this reason, Gu Sileng was greatly encouraged by this incident. With such outstanding seniors. Are there any learning difficulties that cannot be overcome?
Gu Sileng worked in the laboratory day by day. Not just studying astronomy, but also studying physics. math. Chemical. Even mechanics. These are all means of learning astronomy. After countless nights of study, Gu Sileng was finally able to use calculation methods. Calculate the position of a star in the distant starry sky. This excited him. Although the star has been discovered long ago, it can be calculated by hand after all. To this end, he wrote a small paper. Give it to Professor Liu Weichang. Professor Liu Wenxiang is very satisfied with his progress. He said to Gu Sileng: "The position of the stars you calculated was discovered 300 years ago. But your calculation method is unique to you. Although it cannot be regarded as a major scientific achievement, it can be regarded as a master's thesis. , there should be no problem. Through this graduation thesis, you can successfully study at the doctoral level. Gu Sileng, you have to work hard! You have not always come from studying. This means that you have to pay more than others. "Gu Sileng heard Liu Weichang's affirmation. I am very happy to finally graduate with a master's degree. You can enter doctoral studies immediately. This was really a joy for him.
There was one thing that Gu Sileng had not told Liu Weichang. That's what he once discovered at the alien ruins. Objects left behind by aliens on Earth. And I had two conversations with alien prophets. Just like what he said to Zhu Feng. The country knows what happened in the past. He told the country everything. But from now on this is his own secret. Belongs to no one. I don’t want to be involved in this aspect in my work and life. Gu Sileng had always made up his mind like this. But people. Curious by nature. The more forbidden curiosity becomes, the more serious it becomes. Especially subjects like astronomy, which require more curiosity. As Gu Sileng improved in astronomy. Not only did he remember what the aliens and prophets had said to him. Was the prophet speaking to him asking him to discover an alien civilization? Or for the continuation and contribution of human civilization. This was in Gu Sileng, where no answer was obtained. Everything is still unknown. Follow your own exploration and efforts. Just like Yu Zhufeng said. The prophet must have a reason for choosing Gu Sileng. If it was just the first discovery of the ruins, then more than thirty soldiers would have discovered it. Why was it that only Gu Sileng himself saw the prophet? In the following years, the prophet reminded Gu Sileng for the second time. This cannot be said to be a coincidence, but a kind of fate.
Studying at the doctoral level is more in-depth. Gu Sileng had access to a large number of pictures sent back by the Nezha deep space probe. Nezha launches probe. It crossed the solar system more than ten years ago. Like the direction of Proxima Centauri, going away. Brought back a lot of precious pictures and information. This made Gu Sileng very excited and happy. I never imagined that I would be able to do it at the PhD level. Learn such cutting-edge astronomical knowledge. And participated in the research of star screen. Star Curtain is a project shared by renowned astronomers around the world. Join this project. It means making progress together with thousands of peers. one night. Gu Sileng stayed alone in the laboratory. All the colleagues around me are off work. Professor of the research group. They all went home to do other things. He was the only one on duty. On Nuoda's display screen. Later, there were waves of strange sound waves. This sound wave was transmitted back by the deep space probe Nezha. It's not like he's in the universe. Weird white noise. Kind of like the sound of a bug. But it is not the radio waves emitted by intelligent life. Not confirmed yet. This long stretch of sound waves is vividly preserved. Gu Sileng immediately gave it to Liu Weichang. When he called, he also described his findings. Liu Weichang was very surprised after hearing the radio wave. He couldn't explain it either. So he reported it to his superiors.
This strange sound wave. It shocked the Chinese astronomical community. these famous astronomers. It is not possible to understand the launch of the Nezha probe. Whether the sound waves returned are communications from intelligent life. But the interpretation is in full swing. Discovered this sound wave. Gu Sileng received great attention. Chinese astronomers in action. It aroused the curiosity of astronomers around the world. Everyone participated in the decoding of this sound wave. of St. Petersburg University. astronomer. The association sent an invitation to Gu Sileng. Hope, he serves as a visiting scholar. Went to study at St. Petersburg University. This was approved by Professor Liu Weichang. I thought about seeing Natasha soon. Gu Sileng was very happy and excited. Just like Natasha said. I haven't seen him for a year or two. This feeling. It was like fire burning from the soles of my feet to my heart. Fortunately, this time the invitation was from St. Petersburg University. You can study again, and you can meet Natasha naturally. Gu Sileng seemed to want to jump. Liu Weichang of Peking University has agreed. Gu Sileng collected his luggage. And important things to bring. Farewell to Liu Weichang. Got on a plane to St. Petersburg.
The plane in the sky looks like a big bird. Wide-body jet intercontinental airliner. Broad wings. Huge fuselage. Flying in the sky. It's like a large warship flying in the clouds. This is manufactured by the Commercial Aircraft Corporation of China. The most famous wide-body intercontinental jet. This large passenger plane can accommodate more than 340 people. It has taken over 52% of the global market. In modern times this blue planet. Almost most countries are adopting it. It has left Airbus and Boeing far behind. Gu Sileng chose a location by the window. It can be seen through the window. dazzling sunshine. golden sun. On the sea of clouds. It looked extremely brilliant. There are white clouds all around the fuselage. They kept tumbling. Like the waves of the sea. The plane rides on the waves. It feels so good. Planes kept flying in the sky. Gu Sileng was a little tired. He closed his eyes and fell into a deep sleep. When he wakes up. The plane has entered Russia. Customer window looking down. Countless mountains, rolling hills, lush green forests. There is also a waterfall hanging on this mountain. Like silver water washed down. This view is simply stunning. The whole earth. Majestic and vast. with China. The scenery is completely different.
The plane continued to fly to St. Petersburg. I do not know how long it has been. Gu Sileng was a little hungry. The stewardess brought him spaghetti. A small salad. These are all for foreigners' taste. Gu Sileng was not picky either. All three, five and two were eaten cleanly. My belly is slightly bloated. Asked for another glass of fresh orange juice. After drinking all the fresh orange juice, you will feel that cool and sweet feeling. The pain in the abdomen spreads throughout the body. If you feel sleepy, you can take a nap on the plane. When Gu Sileng opened his eyes again, the plane stopped steadily at the St. Petersburg Airport. Get out of the plane. The sun shines on the airport? Appear warm. People left the plane in a hurry. St. Petersburg Airport. It is also considered a large international airport. Although it cannot compare with Beijing Airport, it cannot compare with most airports in China. But the airport here has a rich history. Because it actually worked for many years. Like an old man with white hair and a beard. Everything you tell is a story. Gu Sileng didn't care. Walked out of the airport. Outside he saw Natasha, who was thinking about him day and night.
