From a university student to a chief academician

Chapter 295 Assuming that four-dimensional space does not exist?
Ye Fei said: "Next is the questioning session!"

In an instant, many people below raised their hands.

Ye Fei casually pointed at a middle-aged white man.

The middle-aged Caucasian man stood up, and a staff member handed him a microphone.

The middle-aged Caucasian man put the microphone to his mouth and asked, "Academician Ye Fei, hello!"

"Excuse me, the loop quantum gravity theory constructs a space-time background for string motion, but it still has a huge problem."

"According to string theory, the cosmological constant should be large and positive."

"Moreover, although the ring energy gravity theory can reconstruct the huge four-dimensional space we exist in, it cannot construct the six-dimensional space in string theory that explains the properties of the objects we observe. How can I answer this question? Thank you!"

Everyone in the audience looked at Ye Fei, wanting to know how Ye Fei would answer this question.

This is a very classic problem, and the study of string theory, string motion, and quantum gravity theory cannot avoid this problem.

Therefore, many people present want to know how to answer this question.

Ye Feidao: "This is a very good question. I can draw a pattern and answer this question for you according to the pattern."

After Ye Fei finished speaking, he walked to the whiteboard, picked up a pen and drew a pattern consisting of twelve trapezoids on the whiteboard.

The patterns Ye Fei drew on the whiteboard were displayed in real time on the screens on both sides of the stage.

After a while, Ye Fei put down the pen in his hand, turned to look at the audience and said, "Just like the causal set theory I created, like the loop quantum gravity theory, the causal set theory is a background-independent theory about space and time."

"It starts with a collection of points connected only by guiding principles, and the points are connected by causality."

"Just like the pattern I drew."

"This causal relationship defines how the points are connected in sequence, but is the only principle by which the points in the set obey."

"The observer discovers that the collection of points can produce the physical concepts of time and distance and produce the space-time of relativity."

"The causal set may be associated with the nodes of the spin network in the theory of loop quantum gravity."

"With this relationship, the six-dimensional space can be explained."

Many people suddenly realized when they heard this, it turned out to be like this.

If so, it can indeed explain the six-dimensional space.

The reporters in the back row looked blank. They understood every word of what they were talking about, but they couldn't understand the combination.

How do you explain the six-dimensional space, we also want to know.

The reporters couldn't understand Ye Fei's explanation even if they burned out all the brain cells.

Journalists can't wait to break their heads at the moment.

Ye Fei said, "Next question!"

In an instant, many people below raised their hands again, and Ye Fei pointed to a middle-aged man with a dark complexion who looked like he was from Southeast Asia.

The middle-aged man stood up and asked with a microphone, "Academician Ye Fei, hello!"

"Excuse me, the theory of loop quantum gravity only involves the theory of space-time. How is it explained here?"

"Thank you!"

Ye Feidao: "The theory of loop quantum gravity only involves the theory of space-time, you have to think of it this way."

"It should not discuss the category of objects studied in quantum mechanics, but rather a theory that is context-independent."

When everyone in the audience heard this, they all looked at Ye Fei in surprise.

Does the theory of loop quantum gravity not belong to the scope of quantum mechanics research?

This is not right!

How could it not belong to the category of quantum mechanics research?
Ye Feidao: "Many problems of gravitational theory can be calculated, unlike string theory, which can only be concluded indirectly by summing infinite possible results."

"Let me explain with an example!"

After Ye Fei finished speaking, he walked to the whiteboard and wiped off the pictures on the whiteboard with a cloth.

Then, Ye Fei picked up a pen and wrote a set of numbers on the whiteboard.

【1+1/2+1/4+1/8+1/16+=2.000】

Ye Fei put down the pen in his hand, then turned around to look at the crowd, and said, "Look, everyone!"

"The loop quantum gravity theory can directly get the exact answer 2.0 in one step, while the string theory can only get 2.000 through the summation sequence."

"The Loop Quantum Gravity Theory builds spin networks and spin foams through fundamental spatial elements called nodes and edges..."

"..."

"The nodes, like the one-dimensional loops of the strings in variable chord theory, have no physical meaning in themselves, they are purely mathematical concepts."

"So, if you want to explain the theory of loop quantum gravity that only involves space-time, you should not use the object category of quantum mechanics to explain it, but you should use a background-independent theory to explain it."

"This not only makes the explanation more accurate, but also makes it easier to explain."

Everyone nodded, as if it made sense.

Next, Ye Fei ordered five more people, and they asked Ye Fei questions, and Ye Fei answered them one by one.

Those reporters seemed to be listening to a bible.

They could understand every language Ye Fei spoke, but they were blinded to what it meant when they were combined together.

Tong Siyu asked Yu Mengmeng quietly, "Sister Yu, do you spend every time you participate in such activities like this?"

Activities like listening to the bible made her feel like an idiot.

This made Tong Siyu, who had been a top student since childhood, very speechless.

Yu Mengmeng glanced at Tong Siyu, as if she could see what Tong Siyu was thinking, and whispered: "You have to get used to it, you will often encounter such occasions in the future."

"These people are the group of people with the highest IQ on the planet, we can't compare with them."

"If we compare with them, it is not the difference in IQ, but the difference in species."

"It's like people look at dogs, they look at us, we are equivalent to dogs."

Tong Siyu stuck out her tongue and said with a playful chuckle, "Sister Yu, don't you exaggerate like that!"

"Why didn't you exaggerate so much?" Yu Mengmeng said with a smile: "There is such a big gap between us and them."

Ye Fei raised his wrist to glance at his watch, then put his hand down, and said, "This is the end of today's academic report, thank you everyone!"

After speaking, Ye Fei bowed deeply to the audience.

"Papa..." Everyone present stood up and applauded enthusiastically.

Today's academic report is really worthwhile, not only for them to hear the proof process of Landau-Siegel's zero-point conjecture.

It also let them know the research direction of the unification of quantum mechanics and general relativity.

North America, the home of Edward Witten!
Edward Witten took off the virtual glasses on his face and sat up from the sofa.

Then he didn't put down the virtual glasses, just holding them in his hands.

He was sitting on the sofa with his legs spread apart, his arms resting on his legs, supporting his upper body, holding the virtual glasses in the air with his right hand, tilting his head and frowning in thought.

He reviewed the unified answer of quantum mechanics and general relativity explained by Ye Fei.

After a long time, he suddenly shook his head and said, "No, no, that's not the case. This is contrary to my research."

"Ye Fei proposed the theory of loop quantum gravity."

"And my research is the theory of quantum gravity of strings."

"Ye Fei added his own causal combination theory to his loop quantum gravity theory."

"But many things are assumptions made by Ye Fei. He also assumes that the four-dimensional space does not exist."

"This is not only contrary to my research, but also contrary to many researches in the physics world."

The existence of four-dimensional space is a hypothesis put forward by many studies in the physics world.

"If the four-dimensional space does not exist, it would be contrary to some of Ye Fei's past research. Isn't he refuting some of his past research!"

Some of Ye Fei's research in the field of quantum science also assumes the existence of four-dimensional space.

Now Ye Fei assumes that the four-dimensional space does not exist, which is contrary to some of his research in the field of quantum science.

This is equivalent to hitting the right hand with the left hand, and I have denied my own research.

"If you do this, some of his quantum research will suffer a blow!" Edward Witten shook his head slightly.

"Let's not talk about this, let's go back to the loop quantum gravity theory and the string quantum gravity theory."

"Ye Fei assumed that the four-dimensional space does not exist, which is absolutely wrong."

"Even Einstein said that four-dimensional space may exist, so why did he say that four-dimensional space does not exist?"

"If the four-dimensional space does not exist, then how quantum entanglement travels through the dimensional space, the quantum mechanics that has been studied is also wrong."

"Therefore, it is wrong for Ye Fei to say that the four-dimensional space does not exist."

"So, his theory of loop quantum gravity is also wrong."

"Yes!" Edward Witten clenched his left hand suddenly, and said, "It's wrong."

At this moment, there is a lot of discussion in the world about the theory of loop quantum gravity proposed by Ye Fei.

Because Ye Fei's loop quantum gravity theory can perfectly explain all the problems in the unification of quantum mechanics and general relativity.

But there is a prerequisite, assuming that the four-dimensional space does not exist.

This is impossible.

If it is assumed that the four-dimensional space does not exist, then many theories in the physics world will be destroyed.

This is absolutely not allowed.

Besides, what about quantum entanglement.

It can travel through dimensional space.

If quantum entanglement cannot travel through dimensional space, how can it travel across the entire universe in an instant.

Quantum entanglement travels through the universe This has been proved by experiments. Ye Fei's information can travel across the universe in an instant, which can also prove that quantum entanglement can travel across the universe in an instant.

Since quantum entanglement can travel across the universe in an instant, there must be a four-dimensional space.

The world we live in is a three-dimensional space. If we want to travel through the entire universe in an instant, only when quantum entanglement enters the four-dimensional space can we realize the instant travel in the entire universe.

This also proves that the four-dimensional space exists.

Many people are very entangled.

If four-dimensional space exists, then Ye Fei's theory of loop quantum gravity is wrong.

But the theory of loop quantum gravity is wrong and cannot explain all the problems encountered in the unification of quantum mechanics and general relativity.

But the theory of loop quantum gravity is correct, so the existence of four-dimensional space is denied.

This negates all theoretical research based on four-dimensional space.

This is a dilemma!
At this time, Edward Witten issued an explanation on Twitter.

[About the theory of loop quantum gravity proposed by Ye Fei, I have a few points to explain.

First of all, I am denying the correctness of the theory of loop quantum gravity.

Second, four-dimensional space exists.

Although, so far, it has not been proved that the four-dimensional space exists.

However, based on quantum entanglement, we can assume that it exists.

Since the four-dimensional space exists, the theory of loop quantum gravity is wrong. 】

This statement issued by Edward Witten was quickly spread throughout the physics world, and its influence was also very large.

Who is Edward Witten!

That is the second living physicist in the physics world today, No.1 is Yang Zhenning.

Even if such a character spits out a mouthful of spit, it can attract the attention of the entire physics community.

What they say is often authoritative.

With Ye Fei's current influence in the physics world, he still can't compete with Edward Witten and Yang Zhenning.

Unless, in the field of theoretical physics, he has achieved the same results as these two.

For example, put forward an epoch-making conjecture.

For example, conjectures like the eight conjectures of mathematics.

Or Ye Fei can prove a grand unified theory.

In this way, Ye Fei's reputation and status in the physics world can compete with these two.

Closer to home, after seeing Edward Witten's explanation, many people thought in their hearts: "It is true. If the four-dimensional space does not exist, then what is quantum entanglement?"

"The non-existence of four-dimensional space has a devastating blow to many theoretical researches in physics."

"For example, the 2022 Nobel Prize in Physics is about quantum entanglement, which is based on the premise of the existence of four-dimensional space."

"If four dimensions don't exist, then the research is wrong."

"This also means that the three people who won the 2022 Nobel Prize in Physics should not be awarded."

Jinling, Ye Fei's office!

Ye Fei was sitting behind the desk typing on the keyboard to write something.

At this time, the assistant knocked on the door and came in.

The assistant walked up to Ye Fei and said, "Dean, there are a group of reporters outside who want to interview you."

Ye Fei stopped the movement of his hands instantly, looked up at the assistant, and said in surprise: "Reporter? What are they going to interview me for?"

Ye Fei couldn't remember what he needed to interview recently. His biggest recent event was Zhang Yitang's academic report a week ago.

Ye Fei did not participate in the rest of the activities.

The assistant said: "They want to interview you about the theory of loop quantum gravity."

Ye Fei frowned slightly: "Interview with me?"

Ye Fei also heard that the recent physics circles have been very controversial about the quantum theory of loops he published.

The main point is whether to assume the existence of four-dimensional space.

Ye Feixin said: "It's time to explain, otherwise it's not good to keep them arguing."

Ye Fei did not make it clear at the time about the assumption of a four-dimensional space.

Many people misunderstood what he meant.

Assuming that the four-dimensional space exists, it does not exist either.

And assuming that the four-dimensional space does not exist is just to better explain all the problems encountered in the unification of quantum mechanics and general relativity.

When all these problems are clearly explained, the four-dimensional space can be assumed to exist.

That is, to explain the problems encountered in the unification of quantum mechanics and general relativity.

So assume that the four-dimensional space does not exist.

Because it can easily explain the problems in the unification of quantum mechanics and general relativity.

Wait until the problems in the unification of quantum mechanics and general relativity are explained.

Then discard the assumption that the four-dimensional space does not exist, and instead assume that the four-dimensional space exists.

This behavior looks like a scumbag.

But scum is scum, all these actions are for the unification of quantum mechanics and general relativity.

Ye Fei looked up at the assistant and said, "Take them to the reception room, and I'll go over right away."

Upon hearing Ye Fei's words, the assistant asked in surprise, "Dean, do you want to receive them?"

Ye Feike had never received this group of reporters before, and always told them to leave.

Ye Fei said: "Yes!"

The assistant said: "Okay, Dean!"

After speaking, the assistant left Ye Fei's office.

Ye Fei saved what he wrote, then turned off the computer, stood up and walked outside.
