Yuezhou University, academic lecture hall, Li Banfeng entered the venue to watch an academic debate.

This kind of debate was rare in Yuezhou University and rare in the entire Huan Kingdom.

In normal academic exchange meetings, several industry experts are invited as guests to make some reports in their fields of expertise. Even if there are exchange and discussion sessions, they share some experiences in the scientific research process under the guidance of the host.

Today's situation is completely different. There is no report session, and it goes directly to exchanges and discussions. The two main guests participating in the meeting have completely different views on many academic issues. The discussion between them is likely to turn into a debate.

The main issue to be discussed today is the gravitational tide during the passage through the wormhole.

Li Banfeng found a seat in the back row of the venue and sat down.

Teacher Song was not sitting close to him. She had also achieved a lot of scientific research results in the field of wormholes and was one of the guests at the exchange meeting. She sat in the front row and was ready to participate in the discussion.

On the podium, the 72-year-old professor Yan Youjun, who is the absolute authority in the field of wormholes in China, was the first to speak.

He did not prepare courseware or speech materials, because in his opinion, today's topic was not worth any preparation.

"The tidal effect experienced by travelers when passing through a wormhole must be small enough. This is the basic requirement for a traversable wormhole. To be honest, I don't think there is any point in arguing about such a topic. Less than, what do you think?

?" Yan Youjun took a sip of tea and looked at the forty-eight-year-old Yu Yaoming with a kind smile.

Forty-eight years old is not considered young in most fields, but in front of Yan Youjun, Yu Yaoming must position himself as a junior.

"It's not just him," a female classmate sitting to the left of Li Banfeng adjusted her glasses and whispered to Li Banfeng, "In the field of domestic wormholes, any academic argument that does not conform to Yan Youjun's knowledge

, are all absurd, childish, and not worth arguing about."

Li Banfeng did not look at the female classmate, nor did he make any response. He continued to listen to the old professor Yan Youjun's explanation of the so-called tidal effect, which is the difference in the gravitational force exerted on different parts of an object in a non-uniform gravitational field.

To give a simple example, if a person hits a black hole with his head, his head is closer to the black hole, and his feet are further away from the black hole. The gravitational force on the head is greater, and the gravitational force on the feet is relatively smaller. At a certain distance, the difference in gravitational force between the two is enough.

Tear a person apart, this is the tidal effect.

"The same is true for wormholes." Yan Youjun took another sip of tea. "In extreme cases, the tidal effect of wormholes is no different from that of black holes. Most wormholes are not traversable. Based on the above common sense,

I think there is really no need to argue on this topic.

Of course, there are many people present who are not very clear about the concept of wormholes. I can help you popularize some basic knowledge here. The so-called wormhole is a narrow tunnel connecting two different spaces in the universe, also known as

It is a thin tube of space and time, and it is also a channel to achieve long-distance space travel in a short time -."

Listening to Yan Youjun's explanation, the female classmate said to Li Banfeng again: "Look at how disgusting he is. Even though he knows it is common sense, he still deliberately explains it in detail, as if he is explaining the quadratic equation to a mathematician.

The formula for solving problems is as if the other person is a new student. Yan Youjun likes to use this method to suppress others and make them disgusted."

This method was indeed quite disgusting. At first, Li Banfeng felt that Yan Youjun's words were easy to understand and quite friendly to a layman like him.

But after talking about the basic theory, he will next talk about the history of wormhole research, from the concept of wormholes first proposed by Autry physicists at the beginning of the last century to the later connection between general relativity and wormholes. Yan Youjun

Constantly teaching a scientist who has made certain achievements in the academic field with basic knowledge is like being an elder introducing the uses of soy sauce to a famous chef.

"Wormholes are no longer a new field of scientific research. Countless sages have pointed out the direction for us. What we have to do is to look for newer results in the right direction instead of wasting our precious time on meaningless disputes.

,

An undergraduate student in the Department of Physics can clearly explain the concept of tidal effect. I think it is shameful and ridiculous if this issue is still held in an academic discussion in the professional field!"

After nearly half an hour of explaining the basic knowledge, the old professor finally explained his point of view. In his opinion, Yu Yaoming was a clown who couldn't even understand the basic knowledge.

The female classmate sitting next to her said to Li Banfeng: "If I remember correctly, you didn't continue studying after graduating from undergraduate degree, right?"

Li Banfeng laughed dryly and said, "Do you still remember me?"

The female classmate smiled and said, "How could I not remember you? How many times have I been rejected by you since high school?"

This female classmate is named Fang Yufei. She was a classmate with Li Banfeng in high school. When she was a sophomore in high school, she confessed to Li Banfeng once, but Li Banfeng rejected her.

After the college entrance examination, Fang Yufei offered to go to Li Banfeng's house, but was rejected by Li Banfeng again because Li Banfeng was sleeping in a bridge cave at that time and it was not convenient to receive guests.

The two were both admitted to Yuezhou University, but they were not in the same major. During college, Fang Yufei confessed her love to Li Banfeng three times, but was rejected all times.

To this day, Fang Yufei can still recognize Li Banfeng at the academic exchange meeting.

Her feelings for Li Banfeng are very special, but being able to recognize a Yunshang house cultivator among everyone is not something that can be explained by emotion alone.

Fang Yufei looked at Li Banfeng with a smile. She hadn't seen her for more than two years, but she was still so beautiful. She was the class star in high school. In college, in the College of Science, only Lu Xiaolan was on par with her.

But she is different from Lu Xiaolan. Lu Xiaolan passed all the exams with risks, and some exams even required He Jiaqing's help.

During her undergraduate studies, Fang Yufei's grades were the favorite of the entire School of Science. After taking the postgraduate entrance examination, she became a graduate student at another well-known university in Yuezhou. Such an outstanding girl never lacks suitors.

Right now, there is someone beside her named Han Yuelong. He and Fang Yufei are from the same major, but they are not the same tutor.

Fang Yufei's mentor is Yu Yaoming. Han Yuelong came to this academic exchange meeting today just because he wanted to stay with Fang Yufei for a while.

Han Yuelong didn't know Li Banfeng, but after hearing the conversation between the two, he found that the relationship between the two was unusual, so he made a sarcastic comment to Li Banfeng: "You just graduated with a bachelor's degree? Then you'd better not come to this kind of exchange meeting."

Well, joining in the fun depends on the occasion, there are so many things here that you simply don’t understand.”

Li Banfeng remained silent. If he hadn't been tutored by Teacher Song alone during this period, there were many things that Li Banfeng really couldn't understand.

Fang Yufei turned to look at Han Yuelong: "If he says he doesn't understand, what can you understand? How much do you understand better than him?"

Han Yuelong was a little unconvinced: "I am already in my third year of graduate school. This is my subject direction. I am at least an expert. How can you compare me with an undergraduate?"

"Expert?" Fang Yufei smiled, shaking her head while laughing, "You are not an expert. In this academic lecture hall, there are so few experts that you can count them on one hand."

Han Yuelong was angry. Although he was actively pursuing Fang Yufei, what Fang Yufei just said seemed to hurt his self-esteem: "Then according to your standards, to what extent can one be considered an expert?"

Fang Yufei looked at the podium, her eyes full of respect and admiration: "Listen to the explanations from the experts. This knowledge should not be known to you in the first place, but it will be enough to benefit you throughout your life."

After Yan Youjun's long lecture ended, another professor, 48-year-old Yu Yaoming, finally had the opportunity to speak.

"The focus of today's discussion is that the tidal effect experienced by travelers when passing through a wormhole must be small enough. Is this a necessary condition for passing through a wormhole?

Professor Yan just said that if the tidal effect is too large, when people approach the wormhole, they will be directly torn into pieces and turned into the most basic particles. This does sound like a common sense issue.

But we have ignored another question: What state was the person near the wormhole in at that time?

What kind of form is his life in? When space is severely distorted, will his body still be affected by the tidal effect?"

Yan Youjun asked for the microphone from the host and interrupted Yu Yaoming directly: "Are your statements based on theory, or are they purely wild imaginations? If they are just your imagination, there is no need for me to follow you here.

You're wasting time."

Yu Yaoming smiled and said: "Professor Yan, this is just a hypothesis I made during the research process. Of course, I conducted a lot of mathematical verification on this hypothesis. Although there are still some problems in the derivation process of the theory, the overall

The thinking is very clear, for example————.”

Yu Yaoming had just put his derivation process on the big screen. Halfway through his words, he was interrupted by Yan Youjun: "Don't think that all problems can be solved through mathematical proofs. You can also prove this through mathematics."

The world is two-dimensional, but what’s the point of proving such a hypothesis?”

Fang Yufei said with a stern face: "Ignorant old guy, he interrupted others several times. Look at how uneducated he is!"

Han Yuelong said in surprise: "Professor Yan Youjun is a leader in this field. He is internationally recognized.

How can you say he is ignorant?"

Fang Yufei said with a mocking face: "He is only recognized by a group of laymen. He has lived such a long life in vain. He knows nothing about wormholes."

Han Yuelong said: "This is too much. There are so many experts present today, and they are all here for Professor Yan. You say he knows nothing? Are so many experts blind? Are they all fools?"

"Yes," Fang Yufei nodded, looking first at Han Yuelong and then at Li Banfeng, "They are all blind and fools. You are the same, and I was the same."

Fang Yufei's eyes stayed on Li Banfeng: "I used to think you were so special. I used to think you were so different. In fact, you are no different from them. They are all so ignorant and stupid. I feel sorry for myself.

I feel ashamed because I know so little about wisdom, life, and the world that I have always believed that you are an extraordinary person, so that I wasted so many feelings and fantasies on you.

Fortunately, you are lucky, you have come to the right place today, use your eyes to witness, use your ears to listen, and take a closer look at the power contained in wisdom."

Han Yuelong felt that Fang Yufei was unusual today and she was a little too excited.

Li Banfeng didn't pay much attention to Fang Yufei's status. He was looking at Yu Yaoming's courseware carefully.

Yu Yaoming showed his derivation process step by step in the courseware: "In life as we know it, there is a limit value that can withstand tidal effects. Beyond this limit, the molecular structure of our bodies will be damaged.

This is our basic assumption based on the existing knowledge, because none of us have really been close to a wormhole, and no one knows what changes will happen to us near the wormhole or even in the wormhole.

If we change our hypothesis, we may change from carbon-based life to silicon-based life. Our life form may break the current molecular structure or even atomic structure, thus adapting to the extreme changes near the wormhole.

Or maybe our structure itself does not change, but under the influence of a certain energy, negative energy density appears in a local area, forming a relatively stable environment near the wormhole...

Yan Youjun smiled and interrupted Yu Yaoming again: "Professor Yu, did you seriously think about what you were going to say before you came here? Let's not talk about the atomic structure. Even if the molecular structure changes, is life still called life?

If you burn a living person to ashes, do you think this person can survive?"

"This metaphor is inappropriate," Yu Yaoming continued to demonstrate the derivation process. "Burning a living person into ashes does not involve changes in the nature of space. Changes in the nature of space will bring adaptability to the environment and life.

The evolution of."

"You talk about evolution? Humanity's current science cannot yet restore the evolutionary process of life. You told me that life would evolve near wormholes. When you said this, didn't you feel like a comedian?" Yan

Youjun thought it was ridiculous, so he prepared more intense words.

Several experts watching the debate below couldn't sit still, and they turned their attention to the organizer of the exchange meeting, Vice President Lu Jianpeng.

"Lao Lu, I really made the situation tense. Is it appropriate?"

"This is still an academic exchange meeting. These two people are about to get into a fight. How can there be any academic discussion atmosphere here?"

"I think this is the atmosphere that academic discussions should have," said Lu Jianpeng, who was very satisfied with the current situation. "How did academic exchange meetings work in the past? Five or six experts took turns giving reports. After making the reports, they were interviewed and praised each other.
