On the afternoon of September 30, 2020, Wanghai University.

That's all for today's talk about quantum physics. While there is still some time left after class, I would like to hear some of your thoughts on the future development of physics. After saying this, Zhao Weiguo looked at the somewhat cold classroom and smiled slightly, and then said: "It's not for everyone to be wrapped in food and horses, and fight hard regardless of their bodies, not to be stuffed or flowed, not only to no." Looking at the crowd, he said, "Be positive! ”

The four consecutive allusions made the whole classroom applaud, and the originally embarrassing scene instantly became brighter.

In the hearts of everyone, Zhao Weiguo, a professor at Haida University, compared with those professors who only know how to teach, he likes to listen to the whimsical ideas of these college students every time he finishes a knowledge point, and while teaching, he is also educating people.

After all, imagination is the driving force of scientific progress.

"I~"

"Well, that's good." He smiled and pointed, and a classmate in the third row said, "Tell me what you think." ”

"Professor Zhao, I belong to the category that is not special to humans in the universe. However, after decades of development in electromagnetic communications, human beings have been unable to get a reply from visitors from outside the world when they send all kinds of radio waves. I imagine that when our quantum communication technology develops to a certain extent, will we be able to detect aliens? ”

A little too whimsical, Zhao Weiguo adjusted his brows slightly, and nodded solemnly. "Science is rigorous, no one can deny the existence of a certain thing before there is conclusive evidence, as for quantum science, can it discover the secrets of the universe, the road is long, up and down and seeking, just who is the person who seeks?" As he spoke, he pointed to the students in the audience: "It's you!" ”

The topic of extraterrestrials will always be of interest to these young scholars.

The class suddenly became lively, and someone joked: "The universe is a big forest, and every civilization is a hunter with a shotgun in his hand, waiting to find the other party and fire a fatal blow... Humans can't reveal the coordinates of the solar system."

After this voice came out, the class became more active.

Zhao Weiguo didn't stop the ridicule below, and his face was calm and didn't speak. Under his gaze, a young man in the last row looked very solemn. One hand was constantly rubbing the polygonal jade pendant hanging around his neck. Zhao Weiguo looked at it curiously, but he didn't expect this student to slowly get up from his seat, and he stopped rubbing the jade pendant in his hand. That sudden look up was with a hint of determination.

The young man's name is Luo Chuan, since the incident that happened three years ago that was enough to change his entire life. He had been following that path for a long time, and today he felt that he had come close to the truth. And at this moment, he desperately wanted to show this truth.

"The dark forest is not right, the principle is not right." Luo Chuan's tone was very flat, but his voice was very penetrating. As soon as the words fell, the classroom suddenly fell silent. All eyes were on him.

"Chuanbao, remember not to mess around, use theories, it's best to use theories that Zhao Bu has taught. If you say it's good, the credits will be in hand. A guy sitting next to Luo Chuan said in a deep voice.

Zhao Weiguo nodded at Luo Chuan, he wanted to call his name but couldn't call it, there were still students in his class that he didn't know! "Hmm... This student, please express your opinion from a scientific point of view. ”

"Hello everyone, my name is Luo Chuan, a junior in the Department of Physics." Hearing Luo Chuan's self-introduction, Zhao Weiguo's face was slightly embarrassed.

"What I'm saying is that the relationship between humans and aliens should be a different theory... Xiao Fei, don't pull me..."Luo Chuan pulled his sleeve out of Xie Fei's hand, completely ignoring Zhao Weiguo's expression who was already frowning.

"The solar system is a wild wasteland, the earth is a fishpond in the wasteland, and humans are the fish in the fishpond, and aliens are the owners of the fishpond. The owner of the pond occasionally fishes by the pond, and for the fish, all this is inconsequential, until misfortune falls on him. This is the relationship between humans and aliens, which is called the 'fishpond principle' in a nutshell. After Luo Chuan finished speaking, he didn't care about Xie Fei, a sworn friend who had covered his face with his hands and couldn't bear to see the consequences, nor did he pay attention to the stunned classmates who were all shocked, and he didn't care about Zhao Weiguo's slightly angry face.

Time froze for a full minute, and I don't know who broke the peace, and a burst of laughter from a landslide tsunami rang out from the classroom. Fortunately, this is Zhao Weiguo's class, and the laughter quickly reached a climax, and it quickly disappeared without dragging a trace of tail, so that Luo Chuan did not look too embarrassed.

"Mr. Luo, your idea is very interesting, but as a physics student, all theories are based on theories. Science needs imagination, but it doesn't need fantasy, fantasy that is not based on theory, I can give you a direct conclusion, daydreaming..."Zhao Weiguo accepts the activity of the classroom and the childish imagination of the students, and as he said, he is very repulsive to fantasy, and with a trace of morbid rejection, the occasional ridicule of him is indifferent, but with Luo Chuan's firm demeanor to express his views in class, he is very disgusted, which is disrespectful to science.

Zhao Weiguo was on the verge of getting angry, and everyone didn't dare to make a sound. The next moment is the collision of theory and fantasy. There have been some first-year students who have seen this kind of collision, and they actually have an idea that they feel that their brains are not enough, which makes them doubt their lives, and some people even change their studies to other departments because of this.

"It's not a fantasy, it's a fact." Luo Chuan's face was calm.

"Chuanbao, you're crazy." Xie Fei was anxious, at this time, no method could be used to save the situation, I just hoped that Luo Chuan would say a few words, and at the end of the period, Zhao would not deduct so many points.

"As a junior, I don't believe you haven't heard of the Fermi paradox, so please use this theory to answer your so-called fishpond theory." Anyone who says that the Fermi paradox of extraterrestrial civilization is an unsolvable proposition.

"They're close to existing, so the Fermi paradox itself doesn't hold up, and I don't need to answer it."

"And where are they?"

"I don't know! But they do exist. ”

Luo Chuan replied very simply, and at the same time choked Zhao Weiguo half to death.

"Well, let's use the hypothesis method, and as a scientific researcher, the hypothesis method is also a way to solve the problem. Now let's assume that they exist, as you say, and that the Earth is what you call a fishpond. Then I would like to ask, when the fish in the fish pond are developing with each passing day, and they personally set foot on the moon, unmanned aerial vehicles descend on Mars. Knowledge and cognition are getting wider and wider to the point that from the atoms on the microcosm to the macrocosm of the universe, it has become the knowledge of these fish. In terms of action, opening up the alien planet and stepping into the universe is just a membrane that can be easily pierced by human beings today's technology. I would like to ask if this is not enough to alert the aliens you are talking about? Please answer the question as above. Zhao Wei's Chinese was very fast, and his voice was even more vain when he said it.

"They don't need to be alert at all, because human knowledge is too weak. In other words, in their eyes, our theoretical knowledge is very naïve. It's like a chimpanzee digging an ant's nest with a stick, and it can be ignored at all. Luo Chuan's words fell, making the already very delicate classroom change again.

"Sss The reason why a large group of students gasped was because Luo Chuan began to directly touch Zhao Weiguo's reverse scales. A physics student who directly disdains human scientific knowledge in class and also describes humans as chimpanzees is undoubtedly a direct slap in the face to a professor or a physics professor who has a paranoid approval of scientific theories.

Xie Fei, the only person present who was worried about Luo Chuan, was also dead. It's hopeless, unless Luo Chuan changes departments, otherwise Luo Chuan's miserable situation in this course can be imagined, but the joke of the junior transfer department is not like this.

Luo Chuan's expression was a little flustered, and he grabbed the ancient jade again with one hand at some point, and his expression changed back to calm for a moment, and he fired directly at the Planck constant formula on the projection. "Professor, it's like the rationalized Planck constant formula on the wall, and we can't get a really precise answer to this formula alone."

Luo Chuan, who was in a state of madness, walked out of the ring table directly and stepped into the aisle. Xie Fei just wanted to jump up and hug Luo Chuan, but was pressed back by Luo Chuan.

Luo Chuan walked on one side, and his mouth was like a hanging river. "In rationalizing Planck's constant, h is equal to h divided by twice the π, and the pi in the formula alone does not have a real answer for man."

Hearing Luo Chuan say this, Zhao Weiguo said lightly: "Pi is an irrational number, human beings can only make it more and more accurate through calculation, and in a narrow understanding, he will never have a correct answer." ”

"Yes" Luo Chuan cut off the gold, completely ignoring everyone's eyes, strode onto the podium, pulled over a blackboard, and quickly wrote a formula. "π is equal to redeem" and ignored Zhao Weiguo's angry stop action, and quickly wrote and drew messy characters on the blackboard. After writing a small half of the blackboard in a few breaths, he thought that Zhao Weiguo's feet were in the way, and pushed Zhao Weiguo away with one palm.

The whole classroom was fried, and Luo Chuan's palm just now almost pushed Zhao Weiguo to. Xie Fei saw that something was going to happen, and before everyone could react, he had already rushed to the podium.

"Chuanbao, come out with me." Xie Fei stood on the podium and pulled Luo Chuan out of the door.

And Luo Chuan is very single. "I'm afraid he won't understand, let me note the calculation rules just now."

Remarks, a ghost, who the fuck understands those ghost drawings you wrote? Where does it have a dime to do with Planck's formula? Xie Fei ignored Luo Chuan's reaction, gritted his teeth, picked up Luo Chuan reflexively, and ran out of the classroom as if fleeing.

It was supposed to be a perfect class, but it was turned into a child's play by a junior college student, and he desecrated scientific knowledge in front of him Zhao Weiguo, and he knew what to do next. Pick up your phone and press the shutter the 'ghost drawing' on the blackboard. Drop a sentence: "Class." He walked out of the lecture hall without looking back.
