Of course, before Liu Xiaoguang lit a cigarette for himself, he first handed Cheng Xuedong one.

Cheng Xuedong not only took the cigarette, but also reached out and snatched the whole pack of cigarettes in his hand.

Liu Xiaoguang was stunned: "What are you going to do?" ”

Cheng Xuedong yelled at him and slammed into the entire office: "Do you want to make this small space full of smoke?" ”

Liu Xiaoguang shrugged his shoulders: "There is no way to do this, let's rely on this to relieve pressure." ”

Cheng Xuedong snorted: "Could it be that talking to me will make you feel tremendous pressure?" ”

"This... You know I didn't mean that. ”

"Professor Nan is more stressed than you, but he doesn't rely on smoking to relieve stress. How did you develop such a bad habit? ”

Liu Xiaoguang smiled bitterly and shook his head: "Alas, this is not any pressure, but my personal troubles." ”

Cheng Xuedong was stunned: "That's why you're late?" ”

"Alas, my strong woman wife messes with me every day, and she has a showdown with me directly this morning, so she has to fight for divorce. If I hadn't received a call from you, I wouldn't have known how it would have ended. ”

"Oh, didn't Xiao Xiao worship you in the past? What the hell are you upsetting her? ”

"How can I mess with her? It's not because she's promoted to vice president that she doesn't look down on me, an astronomer who hasn't made brilliant achievements. ”

Cheng Xuedong felt incredible: "Xiao Xiao is not such a worldly woman?" ”

"Alas, people change, especially when social status changes. She is currently the director of a large private company, and she thinks that I have not achieved anything in most of my life, so she dislikes me. However, how can astronomical scientists in our industry make major discoveries? Isn't it a lifetime of obscurity? ”

Cheng Xuedong couldn't help but sigh: "Yes, if we don't make world-class achievements, we will never be recognized and accepted by the world." But we don't have to work so tediously and be prepared to do nothing in this life. ”

Liu Xiaoguang couldn't help but sigh: "But at the current stage of human development, it is becoming more and more inseparable from astronomy, because this is the door to understand nature." ”

Cheng Xuedong questioned: "Did you tell Xiao Xiao about our FAST project?" ”

"She loves astronomy and should know about the launch of this project in our country. However, I did not say that I was also involved in the project. ”

Cheng Xuedong looked surprised: "Why didn't you tell her?" ”

Liu Xiaoguang couldn't help but smile bitterly: "You don't know her at all, just rely on that mouth that doesn't guard the door, if I tell her about this situation, she will definitely say it when she meets someone outside." This can cause unforeseen problems in my work. You went to Professor Nan's house yesterday, and you should know that even Professor Nan's family didn't know that Professor Nan was engaged in this great project. In fact, the organization also requires us scientists who are engaged in this research to keep their families as confidential as possible. ”

Cheng Xuedong pondered: "Actually, women nowadays are quite fond of vanity. Xiao Xiao is much younger than your age, and she is a very strong woman, not only strict with herself at work, but also hopes that her husband will become a Chan. If you make a career in astronomy, it will make her feel extremely proud. So, in order for her to support your work, you'd better reveal this truth to her. ”

"But isn't that a violation of organizational discipline?"

"As long as you gently offer to help you keep it secret, she will be happy to cooperate with you. After all, in the past, all major projects at the national level needed to be concealed. Think about how she admired us who were engaged in cutting-edge scientific research. Besides, our project is still in the preparatory stage, and when the official construction is completed, you may be away from your family and have to work outside for a few years, if you don't have her support, it will be difficult for you to work with peace of mind. For example, if you only work a few extra shifts outside in the preparation stage of your work, it has already aroused her strong dissatisfaction. Therefore, during this period, we must not have a fire in the backyard of our house. ”

Cheng Xuedong's words couldn't help but remind Liu Xiaoguang of the scene when he met Xiao Shuyun...

It was more than 10 years ago that the Unigroup Observatory welcomed a group of local university students to visit. During the visit, of course, this group of young people had a very important program, which was to look at the full space through the space telescope of the observatory.

This makes every young college student eager to try it. Their expressions of excitement were palpable, and they almost scrambled to see the telescope.

Liu Xiaoguang was only about 30 years old at the time, and he was a talent, responsible for receiving those young college students who still had a youthful and childish face, and in the eyes of these young people, he was like a mentor, guiding them to observe and telling them astronomical knowledge.

At the end of the visit, he was invited to ask questions from the university students, of course, all about space knowledge.

Liu Xiaoguang smiled and answered fluently.

"May I ask Mr. Liu, one day in the future, will human beings really be able to immigrate to other planets?"

Liu Xiaoguang faced the expectant eyes of the college students and calmly replied: "Since the successful landing of human beings on the moon, the migration between planets is not a dream, with the rapid development of science and technology, human beings can build special buildings suitable for survival on those planets where life is forbidden area." Not only can you do scientific research there, but you can also go on vacation. Of course, it is not yet suitable for permanent residence. ”

"Are there any other planets besides the moon that I can visit?"

"With the advancement of science and technology, mankind can conquer not only the moon, but also other planets and moons in the solar system. For example, the moons of Mars and Saturn, whose environment is similar to that of Earth. ”

"Teacher Liu, you keep claiming to be 'human', does this include us Chinese?"

In the face of some college students' sharp questions, Liu Xiaoguang humorously replied: "May I ask this classmate, are Chinese not in the scope of human beings?" We Chinese are no more stupid than anyone else, and of course we can travel in space. Hasn't our Shenzhou spacecraft already sent our astronauts into the long space journey? As long as we get our science and technology up, sooner or later we can leave the footprints of our Chinese on other planets! ”

Bang Bang Bang!

Liu Xiaoguang's passionate speech won warm applause from the college students at the scene. At this moment, every college student, including Liu Xiaoguang, is boiling in blood.

One of the female college students was a little excited and couldn't help but stand up: "Teacher Liu, can I ask you a question?" ”

Liu Xiaoguang looked at the young female college student and couldn't help but feel moved. In fact, when he guided them to observe the astronomical telescope, he already favored the female college student and gave the other party more satisfaction, because she was different - her figure was in a purple dress, which showed her wonderful body vividly. That beautiful face perfectly matches the youthful and beautiful figure, and on that fair face, a pair of big watery eyes fit the smart and clever look. Under the five black hairs, two curved eyebrows, like the crescent moon. Between the rosy lips is a row of white, neat teeth.

Liu Xiaoguang, who is still alone, can be said to fall in love with her at first sight, because in the other party's body, she embodies exquisite cuteness.

"What is this classmate's name?"

Liu Xiaoguang did not immediately agree to the other party's question, but first asked the name of the person, and as soon as this remark came out, his cheeks immediately became a little feverish.

The young female college student looked unconcerned: "My name is Xiao Shuyun." Excuse me, can I ask Mr. Liu a question? ”

Liu Xiaoguang hurriedly nodded: "Of course you can, I know everything about every one of your classmates' questions." Please sit down and ask questions. ”

Xiao Shuyun did not sit down, but stood up and asked: "Since you are a very knowledgeable astronomer, can you tell us if there is life outside the planet we live in?" ”

Liu Xiaoguang replied with a smile: "Theoretically, there must be." Because the universe is vast and vast, there will be many stars like the earth, and perhaps more advanced civilizations than our planet. ”

"What is the most advanced civilization you are talking about?"

"This... It should be that aliens are more intelligent than us, and their technology is more advanced than ours, and they can even be more than 10,000 years ahead of us. ”

"Oh, if that's the case, will they invade our Earth?"

Liu Xiaoguang shook his head with a smile: "Probably not." Because even if there is such intelligent life, it is extremely far away from our planet. Their aircraft will not be able to reach the Earth, let alone invade us. ”

"In that case, can we reach them?"

"This..."

Faced with one question after another from female college students, Liu Xiaoguang was a little overwhelmed.

Xiao Shuyun blinked her big mischievous eyes: "Isn't this question easy to answer?" ”

Xiao Shuyun hurriedly improvised and said: "This question is difficult to answer, because the current level of human science and technology is not yet up to the level of life in outer space. So, it doesn't support this issue yet. ”

"Since we can't get in touch, can we see them through the telescope just now?"

Liu Xiaoguang couldn't help but smile bitterly: "As I said, the current level of science and technology mastered by our human beings is still limited, and even the function of our astronomical telescopes needs to be improved. If human beings can develop astronomical telescopes that can see farther and have higher resolution in the future, they may be able to see life in outer space living and reproducing on a distant planet. ”

"Really? If we can make eye contact with them, it will be a very romantic thing. ”

Liu Xiaoguang looked at this beautiful and curious girl, and couldn't help laughing: "The girl is so naïve to think about it. Even if we could make eye contact with them, we wouldn't be able to communicate with them. ”

Xiao Shuyun hurriedly explained: "I mean eye movement contact, like two ships waving flags at each other in the ocean far apart. ”

Liu Xiaoguang may have liked her naïve and reverie-filled energy, so he patiently explained: "We can let intelligent life in distant outer space see it, and we rely on the light emitted by ourselves for the other party to capture." For example, if our current situation is captured by others, I am afraid it will take tens of thousands of light years, or even longer. In this way, if life in outer space can observe our planet through high-tech means, it can only observe primitive societies, and even more distant dinosaur times. If we advance in science and technology, we can observe them one day, then we will not observe them now, but thousands of years, tens of thousands of years, or even millions of years ago. ”

"Huh? Is that really the case? ”

"Not at all." Liu Xiaoguang continued, "For example, we humans recently observed that a star in the Milky Way galaxy exploded, and according to the analysis of the light beam it reflected to the earth, it exploded tens of thousands of years ago, and the light has just been reflected into the human field of vision. ”

Xiao Shuyun's answer to Liu Xiaoguang was finally convinced: "Teacher Liu, you are really amazing, you can forward-looking understand the infinite mysteries of the vast emptiness. ”

Liu Xiaoguang smiled proudly: "Our scientists engaged in astronomical work are to learn more about the truth of the universe through the spirit of diligent exploration, and to serve all mankind. ”

At this moment, Xiao Shuyun's admiration for Liu Xiaoguang revealed affection in her eyes at the same time.

Liu Xiaoguang was also full of affection for this curious girl, and although they stopped communicating verbally, their eyes kept interacting with each other. This made Liu Xiaoguang very distracted, so that he was a little distracted when answering the next questions of other college students, and as a result, there were some 'donkey lips are not the same as the horse's mouth', which caused the universities to laugh from time to time.

Liu Xiaoguang's face was embarrassed, and he glanced nervously at the beautiful female college student.

Xiao Shuyun seemed to understand that his gaffe had something to do with him, and couldn't help but sneer, while avoiding his gaze shyly.
