On the campus of Koro University, under the shade of green trees, you can see a series of youthful and beautiful figures. Pen ~ fun ~ pavilion www.biquge.info most of them are from China, there are also from the United States on the other side of the Pacific, and many people are from Europe on the far side of the earth.

The relaxed and diversified philosophy of running the school makes it possible for students to quickly integrate into this young university no matter where they come from.

At this moment, on the brick and stone road full of the atmosphere of books, students are holding books and walking in groups of three or five, walking in the direction of the teaching building. It's a rarity in normal times, but it's rare on weekends.

"Eh, have you heard? That Jiang Chen is coming to our school to give an open class!"

"Jiang Chen is the chairman of Jiang Chen's Future People Group and the founder of the virtual reality network?"

"Really?!What are you talking about, I ask to skip class!"

"Cosmology. Said the girl who wore glasses and looked very quiet.

“……”

“…… House...... Cosmology?"

“…… Is it science?"

"It's really unexpected, I thought he would talk about economics, the Internet and something. ”

"Hee-hee, do you still have to skip classes? It has nothing to do with our major. ”

"Nonsense, do you need to ask!" said a girl with little stars in her eyes and excitement.

"After all, it's the world's richest man's lecture! I heard that Harvard University wanted to ask him to explain the artificial intelligence database and the three definitions, but he didn't go!" another girl also chimed in.

Indeed, there are not many opportunities to listen to the lectures of the world's richest man, especially this Mr. Jiang Chen is quite low-key, except for showing his face at the opening ceremony last year, he basically rarely appears on this campus.

Even though the name of this public elective class was rather strange and seemed to have nothing to do with the field Jiang Chen himself was involved in, it still did not hinder people's curiosity about him.

No matter what the purpose was, when Jiang Chen walked into the lecture hall, he saw that the classroom was already crowded.

The classroom, which can accommodate more than 200 people, is slowly being crammed at the moment, and some people even moved stools from the next classroom and simply sat in the aisle.

Looking at the enthusiastic faces, even though he was used to seeing big scenes, Jiang Chen's scalp couldn't help but feel a little numb.

Then he remembered the malicious laughter of Principal Rafael Leif on the phone yesterday. Sure enough, the old guy said that if he held this open class, no matter how unpopular the course was, the classroom would definitely be full.

The scalp is numb, and stage fright is of course impossible.

How to say that he is also the leader of hundreds of thousands of people, and in the last days, he is a "big warlord" on one side, and only a hundred or so students are not enough to make him stage frightened.

Smiling and waving his hand to the audience, Jiang Chen turned on the headset hanging next to his ear, coughed lightly and tried to make a sound, and then spoke.

"Surely everyone here is wondering why the man standing before you today would pick the inexplicable subject of cosmology instead of imparting something more useful or practical about success?"

The noisy voices in the classroom gradually subsided, and everyone looked intently at the position of the podium and at Jiang Chen's face.

That's an easy question to answer. James Glassman, a well-known economist and Wall Street investor, recently published a book that took me as the subject of his research...... Of course, it seems to me to be one-sided...... Analyze why it took me and my future group to stand at the top of the pyramid from nothing in just three years. As he spoke, Jiang Chen smiled and looked at all the students present, "I don't agree with his argumentation process, but I agree with his conclusion." ”

"That is, my success story cannot be replicated. ”

"Since my experience is not replicable, it is not a good medicine for you, and it may be just a poison. ”

"But apart from business success, I don't think there's anything else I can do better than you. So, I chose a topic that I was personally interested in and studied a little, that is, cosmology, which I am going to talk about today. ”

Jiang Chen noticed that many students had picked up their mobile phones and were enthusiastically recording videos.

But he didn't care, what he was going to say today was originally to throw bricks and attract jade.

As he spoke, he turned around and picked up the marker and wrote four words on the whiteboard.

Where are they?]

Turning around, Jiang Chen put the marker pen on the table and set his eyes on everyone present.

"Where are they? I think all of you here are familiar with it. That's right, it's the famous Fermi paradox. ”

"It is estimated that the number of stars in the observable universe is probably between 10 to the 22nd to the 24th power of 10, and the amount of sand on Earth is 7.5 x 10 to the 18th power. After a pause, Jiang Chen smiled, then spread his hand and said, "In other words, every grain of sand on the earth can correspond to 10,000 planets in the universe. ”

"The universe is far bigger than we imagine, and darker than we imagine. ”

"This darkness does not come from some aliens, and all civilizations are humble and small in the face of the time scale of 13.8 billion years. Perhaps on Mars at our doorstep, the spark of civilization has sprouted. It's just that it ran out of life a billion or tens of billions of years ago, and a billion years ago the earth was just a chaotic ocean, and even trilobites didn't exist. ”

"This is what is called the cosmic sieve. The probability of our encounter with extraterrestrial civilizations is very small, and the probability of discovering each other after meeting is even more remote. ”

"But we still have to make assumptions that if we meet extraterrestrial civilizations, we happen to be able to discover each other and understand each other's existence. Then I can assert that the consequences of blind contact will be quite dangerous......"

Understanding does not imply identification, and disidentification leads to conflict. This kind of identity is embodied in many aspects such as aesthetics, values, and core values, just like the soul of the dead who takes death as beauty, and absolutely cannot accept each other with the living who sing the praises of life.

Jiang Chen didn't expect his class to inspire these students too much, and many of the arguments he presented had already been discussed before.

He just wanted to see how the students would react when he told the truth.

Through the reactions of these students, it is possible to make at least a rough assessment of the consequences of publicizing the crisis facing the earth's civilization.

The class is coming to an end.

“…… What if, I mean, there is a colony ship from an extraterrestrial civilization on its way to Earth. We don't know where it came from, and we don't know for sure if it came with good intentions, but if you were a decision-maker on Earth's civilization, what decisions you would make after learning about this information. ”

"This is your homework, and I hope you will do it carefully. ”

Jiang Chen noticed that many students in the audience looked quite interested in their expressions after hearing this assignment.

Obviously, no one really takes this inexplicable assignment seriously. After all, no matter how you look at it, this assignment is really boring. They are no longer at that childish age to fantasize about space, about the first contact between humans and extraterrestrial civilizations, about unrealistic questions.

Maybe a job, a scholarship, or a professor's project will make them think about it seriously.

Thinking of this, Jiang Chen couldn't help but smile and shook his head.

Straightening out the books on the table, he coughed lightly and said to the students who were about to get out of class.

"Well, I know you're not interested in that, so I'll get straight to the point. ”

"I believe that those of you who often play with mobile phones and wear helmets will be familiar with the space colonization plan of the Star Ring Trade. You may find extraterrestrial civilization research part of Ring Trade's space colonization program, and you may find it boring, but for now I'm telling you, there's commercial value in this subject. And this assignment I assigned is related to this topic. ”

"The prize money for the project is 10,000 US dollars, and ten qualified papers will be selected. If you're interested, then submit a paper to me. By the way, students who have not enrolled in the course can also participate, and the mailbox is on the whiteboard. I'm more afraid of trouble, so I posted my bank card account number in the mailbox and sent it over......"

Before he finished speaking, Jiang Chen noticed.

Those pairs of eyes, looking at themselves suddenly changed...... (To be continued.) )
