Professor Wei's voice suddenly froze, and the other people in the video conference couldn't help but be stunned.

"There are 793 scientists participating in the video conference, and you are all the elite future of mankind and the most critical link in the development of human civilization.

So far, human beings have only come into contact with two extraterrestrial intelligent civilizations, one of which has been extinct for 4 billion years.

In the case of speculation and precautions against extraterrestrial civilizations, in the absence of sufficient data samples, everyone is afraid to determine the situation of the other party. ”

The smile on Lu Yi's face that had been continuous was put away, and he said with some hatred: "Once the civilization information is known by the alien civilization, what awaits mankind is to die out within a hundred years like the Muba civilization 4 billion years ago."

Whether your research is important, or the safety of civilization, I don't think I need to say this question, everyone will have the answer in their hearts.

Let me ask all of you who participated in the video conference, do you know anything about the fourth-level civilization? Do you know their social formation, do you know their technology?

You don't know!

For the fourth-level civilization, what do you know besides knowing a gravitational space-time technology?

Gravitational space-time technology is just one core, just like nuclear technology.

What is the technology that has been developed from this core technology, and how many, you don't know anything except a curvature engine!

You can't even guarantee the success of your scientific research projects and your own work, so why do you think that the mysterious fourth-level alien civilization has already left?

Where is your rigor as a scientist? Where has your patience and persistence as scientists gone?

Is it that after the breakthrough of controllable nuclear fusion, abundant resources, and the explosion of productivity, the scientific research resources allocated to everyone have increased, and life has become comfortable, and even the basic rigor and patience of scientists are gone? ”

"To be honest, I'm disappointed, I don't think you, as a civilized brain, as a scientist, will not be so short-sighted.

But I'm sorry, but I expected too much.

The Recorder is requested to communicate the resolution of this meeting to the Heads of State at a later date...... In addition to the continuation of the construction of the super-large gravitational-wave observatory, the search for an unknown fourth-level civilization and the construction of a semi-permeable layer of the Dyson sphere in space were suspended.

Congratulations, 60% of the scientific research resources in the scheduled research plan will be allocated to you in a few days. ”

Lu Yi shook his head with some interest, packed up his things and stood up, beckoning Zhang Qing and Lin Meng to leave.

"Let's go."

"Hmm."

Zhang Qing and Lin Meng nodded, and also picked up their things and left the video conference room with Lu Yi, leaving a silence and silence behind them.

"Lu Lu ......"

Walking out of the conference room, Professor Lin suddenly reached out and grabbed Lu Yi's hand, turned his head and looked at him with some concern.

"It's fine."

Lu Yi showed a smile on his face, squeezed Professor Lin's hand with his hand, turned his head to Zhang Qing and asked, "How is the progress of the three super-large gravitational wave observatories, and when will the space assembly be completed?" ”

This incident involves a fourth-level civilization, and Lu Yi needs a person who has studied gravitational wave observatories and gravitational waves as an assistant, so Zhang Qing, who had to stay in the gravitational wave research center for two years, was called out.

"The relevant module components are still in production, and according to the current progress, it will take about seven and a half months to assemble and complete the commissioning."

Human productivity is already very strong, and in the past two years, there have been seven or eight more companies that can manufacture laser interferometric gravitational wave observatories, including Tomorrow Group, which also has a dedicated R&D and manufacturing department.

Therefore, with the mobilization of resources that can be mobilized, three gravitational-wave observatories with an arm length of 1,000 kilometers will take about 9 months before and after.

After all, 1000 kilometers sounds terrifying, but in fact, it is a vacuum tube with a damping structural layer, and it is not difficult to industrialize manufacturing with sufficient materials, but the biggest difficulty is assembly and commissioning.

"How long does it take to finish one first?"

"It's almost 2 months."

Zhang Qing estimated the time, the module module has produced enough to assemble more than one gravitational wave observatory, and 2 months is actually the assembly and commissioning time.

As for sending into space, launch vehicles have already been phased out, and the adoption of several Starships can be completed in less than two days.

"Hmm."

Zhang Qing made a note of this matter and suddenly asked, "Is it appropriate for us to suspend the search for that fourth-level civilization and semi-permeable membrane layer?" If that fourth-level civilization really didn't leave......"

"Conventional technical search is meaningless, and the semi-permeable membrane can only be passively defended, and it is useless to open the active detection semi-permeable membrane.

If that fourth-level civilization really hasn't left, it's almost enough to observe and observe for more than a month, and the next thing should be to get our civilization information. ”

Lu Yi rubbed his temples, sighed a little tiredly, and said, "And that group of scientists really needs to be appeased, each of them represents one or more scientific research teams behind them.

The unknown fourth-level civilization crisis needs to be eliminated, but the development of civilization is inseparable from them, and it is difficult to bring the team when people's hearts are confused.

I hope that after the completion of the super-large gravitational wave observatory, it will not be able to find abnormal gravitational wave signals in the solar system, otherwise this is an invasion of civilization that is even more terrifying than the blue people. ”

Although because of that fourth-level civilization, human beings have already paid a lot of manpower and material resources, in Lu Yi's heart, he would rather hope that these resources were paid in vain, rather than that human beings are really targeted.

......

Time is slowly passing, and half a month later, major colleges and universities across the country have also started school and are on the right track.

According to the course arrangement, the afternoon class of the interstellar major is the core technology of civilization, and the professor is Lu Yi.

Lu Yi, who was unable to take time to attend the opening ceremony, took time out of his busy schedule to pass CUHK.

"Hurry up, Zhang Wei, run faster, it's too late and you don't even have a place to stand!"

Before the start of class, there was a small commotion at CUHK, and students were rushing to the school's large classrooms.

There is no restriction on auditing all courses in the interstellar major, as long as it is not noisy or disruptive, any student is welcome to come and audit.

Therefore, the most lively thing on the CUHK South campus every day is the interstellar major, and it is rare for the science bigwigs to even meet, let alone listen to their lectures.

When Lu Yi came over, he didn't go up yet, but he saw that the corridors were full of students, and more than a dozen security guards and school leaders were working hard to maintain order to avoid a riot and a stampede.

Seeing this scene, Lu Yi turned his head and instructed the management director of the interstellar major next to him:

"Interstellar has a video teaching system, open two more classrooms for standing students to go to the video classroom, and the video can be shared with other colleges and universities simultaneously."

The management director stretched out his finger and pointed at the students who were still running this way behind him, and said with a wry smile: "Professor Lu, don't persuade me." ”

Those students who have classes to attend can still be persuaded to leave with reasons such as absenteeism, but for these students who have no classes, Lu Yi said that they are allowed to audit, so they will all come over.

“......”

Fill in the pit he dug by himself, Lu Yi shook his head helplessly, and walked upstairs.

"Senior brother is here, let's give up a place!"

Seeing Lu Yi coming, the students in the corridor consciously moved out of the way so that Lu Yi could enter the classroom.

There is not much noise and noise, and occasionally a few people whose quality is not up to par are also silenced under the eyes of the people around them.

"It seems that I'm more popular, and there aren't so many people in your Senior Sister Zhang Qing's lecture in the morning."

Lu Yi made a joke with a smile on his face, and then said seriously: "But for the two-hour class in the afternoon, it is not good for students to stand like this, and now students who do not have seats to stand listen to the school's arrangement to go to the next classroom, and the situation on this side will be synchronized with the video screen."

Starting tomorrow, all the lecture videos of the interstellar major will be uploaded to the official website simultaneously, and students who are interested in learning about the teaching of the interstellar major can watch it on their mobile phones or computers in the dormitory.

Students who want to come to the audit will open 10 audit places one day in advance, and everyone will draw the number on the official website with the student number.

One thing to note in the auditors is that no questions are allowed.

The bigwigs who came to teach were personally invited by your senior brother to pull down their faces, and their time is very precious, if everyone asks questions together, then they don't have to lecture.

Younger brothers and sisters are obedient, this is your senior brother's first class, so many of you are standing and looking at me, I am really a little nervous. ”

Speaking of the back, Lu Yi raised his hands and waved at all the students.

"Haha."

Hearing Lu Yi say that he would be nervous, everyone couldn't help laughing, and then began to walk towards the video classroom next to him very sensibly.

"Let's go, listen to Senior Brother, let's go over and watch the live video."

Under Lu Yi's strong appeal at CUHK, a few minutes later, all the students standing in the corridor and classroom were emptied, and there was no big accident in the whole process, except for a few excited primary school girls who ran to Lu Yi's side to talk and ask for autographs.

"Stand up!"

"Hello teacher!"

As soon as Lu Yi entered the classroom with his notebook, there was a uniform greeting in his ears.

"You may be seated."

Glancing at his sister sitting in the middle, Lu Yi opened his notebook and projected out the courseware prepared in advance, and started his first lecture.

"The content of this class is to talk about the classification of cosmic civilizations, and before talking about classification, let's talk about aliens."

"In 1951, the famous physicist Fermi asked the famous question: Where are they?"

"This problem is the famous Fermi paradox, for decades, we humans have had a lot of speculations and fantasies about aliens, and even sent probes to find aliens in history."

"For decades, we have not been sure whether there are aliens in the universe, because there has been no trace of aliens, we have proposed the big filter theory, put forward the distance theory, put forward the theory of life development, etc., trying to explain why the aliens have not been found from various angles.

Because we would not be so naïve to think that the universe with a diameter of 13.8 billion light-years will only give birth to an intelligent race of human beings. ”
