Professor Wei's voice suddenly got stuck, and the other people in the video conference were also stunned.

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

As of now, humans have only come into contact with two alien intelligent civilizations, one of which has been dying for 4 billion years.

In the speculation and prevention of alien civilizations, no one dares to be sure of the other party’s situation without sufficient data samples.”

Lu Yi's smile continued to hold up, and said with some regret: "Once the information of civilization is known to alien civilizations, what awaits humans will disappear within a hundred years, just like the Muba civilization 4 billion years ago.

I don’t think I have to say about this question, everyone will have an answer in their hearts.

I would like to ask everyone who participates in the video conference, do you know about Level 4 civilization? Do you know their social form and their technology?

You don't know!

For level 4 civilizations, what else do you know besides a gravitational space-time technology?

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

What is the technology that has been developed from this core technology and how many are there? You don’t know anything except a curvature engine!

You can’t even guarantee 100% success in your scientific research projects and your own work. Why do you think that the mysterious Level 4 alien civilization has left?

Where did your rigor as scientists go? Where did your patience and persistence as scientists go?

Is it because of a breakthrough in controlled nuclear fusion, abundant resources, and after the outbreak of productivity, the scientific research resources allocated to everyone, life is more comfortable, and even the basic rigor and patience of scientists are gone?”

"To be honest, I'm very disappointed. I think everyone, as a civilized thinking brain and a scientist, will not have such short-sighted eyes.

But I'm sorry, I had too high expectations.

Please inform the resolution of the recorder of this meeting to the heads of state later... In the original plan proposed, in addition to the continued construction of the super-large gravitational wave observatory, the search for unknown level 4 civilizations and the construction plan of the Dyson sphere semi-permeable membrane layer in the space requested a suspension.

Congratulations to everyone, everyone's scientific research resources in the scientific research plan will be transferred to you in a few days."

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

"let's go."

"Um."

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

"Lu Lu..."

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

"fine."

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

This incident involved a level 4 civilization. Lu Yi needed someone who had a relatively good study of the gravitational wave observatory and gravitational wave as his 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 being produced. According to the current progress, it will take about 7 and a half months to assemble and complete the testing."

Human productivity is already very strong. In the past two years, companies that can create laser interference gravitational wave observatory have also increased. No. 7 Middle School. Students who are interested in understanding the teaching situation of interstellar majors can watch it on their mobile phones or computers in the dormitory.

Students who want to attend will open 10 attendees a day in advance, and everyone will draw lottery on the official website based on their student account.

Pay attention to the listening, that is, questions are not allowed.

The big guys who came to teach were invited by your senior brothers. Their time was precious. If everyone asked questions together, they wouldn't have to give lectures.

Junior brothers and sisters are obedient. This is the first time your senior brother has been in class. So many of you stand and look at me, so I feel a little nervous."

Speaking of the latter, Lu Yi even raised his hands and bowed to all the students.

"Ha ha."

When everyone heard Lu Yi say he would be nervous, they couldn't help laughing out loud, and then they began to walk towards the video classroom next to them with a sensible sensibility.

"Let's go, listen to my senior brother, let's go and watch the live video next to you."

Under Lu Yi's powerful appeal at the University of China, a few minutes later, all the students standing in the corridor and in the classroom were cleared. The whole process was not a big accident except for a few excited elementary school girls who ran to Lu Yi to chat and talk and ask for autographs.

"stand up!"

"Hello teacher!"

As soon as Lu Yi took his laptop into the classroom, a uniform greeting came from his ears.

"Please sit."

After looking at the sister sitting in the middle, Lu Yi opened his notebook and projected the courseware that had been prepared in advance, and began his first lecture.

"The content of this class is about the grading of cosmic civilization. Before we talk about grading, let's talk about aliens first."

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

"This question is the famous Fermi Paradox. Over the past few decades, we humans have had many speculations and fantasies about aliens, and even launched probes to find aliens in history."

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

Because we won't really be so naive to think that the universe with a diameter of 13.8 billion light-years will only give birth to a wise race of human beings."
