From university academician to chief academician

Because there is nearly twelve hours of time difference between Beili Kingdom and Xia Kingdom.

Therefore, when Xia Guo held an academic seminar, Beiliguo's academic seminar had not yet begun.

Therefore, at this moment, many people around the world are watching the Magic City academic seminar in the metaverse.

The international mathematics and physics communities attach great importance to this academic seminar.

After all, one is the proof of the Landau-Siegel zero-point conjecture, and the other is Ye Fei’s complete and consistent theory of quantum mechanics and general relativity.

These two research fields play a very important role in mathematics and physics respectively.

Beiliguo, in a small villa near Princeton University!

In the study room of the small villa, an old white-haired white man with a high hairline was lying on the sofa against the wall.

His name is Edward Witten, a Jewish North American physicist and mathematician, Fields Medal winner, professor at the Institute for Advanced Study in Princeton, and a top scholar of string theory and quantum field theory.

He was once rated as the sixth most influential person in the world after 1945 by the magazine "Life" in North Korea.

He is also the person with the highest H index in the physics world today.

H-index is a hybrid quantitative index that can be used to evaluate the quantity and level of academic output of researchers.

At the same time, it is also called h factor, high citation count, etc.

Although many scholars are capable, the number of published papers is very small, resulting in an H-index that is not consistent with their own abilities.

For example, Ye Fei, Yang Zhenning and others.

They publish very few papers, so their H-index is not very high, and they are at the middle to lower level among many top scholars.

However, a low H-index does not necessarily mean poor ability, and a high H-index does not necessarily mean strong ability.

As the person with the highest H index in the current physics world, one can imagine Edward Witten’s ability.

Someone once divided all physicists in the world into three grades.

Newton, Einstein and Maxwell belong to the first category.

Galileo, Faraday, Bohr, Planck, Heisenberg, Dirac, Schrödinger, Yang Zhenning and Rutherford belong to the strong second level.

Landau, Pauli, Feynman, Marie Curie, Weinberg, Edward Witten, Higgs, and twenty or thirty others belong to the weak second level.

Ding Zhaozhong, Gao Kun, Li Zhengdao, Nanbu Yoichiro... belong to the third level.

As for Ye Fei, since Ye Fei has only become famous in recent years, and this ranking was done in 2017, there is no Ye Fei.

Many people in the physics community have said that if Edward Witten's theoretical research is confirmed, then he can enter the first gear and even compete with Newton for the first place in history.

From this we can imagine how powerful Edward Witten is in the physics world.

Of course, the prerequisite is that the theoretical research is confirmed, otherwise it will belong to the weak second level.

Edward Witten was wearing virtual glasses, lying on the sofa, watching Ye Feiyao on the stage start to speak.

"Zhang Yitang's Landau-Siegel zero-point conjecture was indeed proved successful by him, and the entire proof process was correct."

"If he can successfully prove the Landau-Siegel zero-point conjecture, it seems that he will have a place in next year's Wolf Prize in Mathematics, and he will also join the list of the world's top mathematicians."

Edward Witten did not attach much importance to Zhang Yitang's proof of the Landau-Siegel zero-point conjecture.

For the world's top mathematicians and physicists like him, unless the eight conjectures of mathematics can get his attention, other mathematical research will not get his attention.

Edward Witten looked at Ye Fei on the stage with great anticipation: "I wonder what new research Ye Fei can do in the fields of quantum mechanics and relativity."

Edward Witten attaches great importance to Ye Fei, who has become famous in recent years.

Especially after Ye Fei developed the Metaverse, Ye Fei's reputation reached its peak. Many people said that Ye Fei would be the greatest scientist in the 21st century.

Edward Witten is not convinced about this.

If Ye Fei wants to become the greatest scientist in the 21st century, he must first get through me.

If he cannot surpass me, he will never be able to become the greatest scientist of the 21st century.

"Is quantum mechanics and general relativity a complete and consistent theory?" Edward Witten frowned slightly, a trace of thought flashing in his eyes.

He has worked on complete and consistent theories of quantum mechanics and general relativity.

The complete and consistent theory of quantum mechanics and general relativity is actually the basis for the unification of quantum mechanics and general relativity.

The ultimate goal of mathematics is to prove the eight major conjectures of mathematics.

The ultimate in physics is the theory of everything, which refers to a formula that can explain all the physical mysteries of the universe.

The theory of everything is a combination of many grand unified theories.

Among them, the unification of quantum mechanics and general relativity is one of the grand unified theories.

"Is he now studying the unification of quantum mechanics and general relativity?"

"This is very difficult. Countless physicists have been studying it since Einstein's time, but they haven't found anything yet."

"Ye Fei wants to prove the unity of quantum mechanics and general relativity, which requires his lifetime research."

If a physicist can prove one of the grand unified theories, he will be ranked as one of the greatest physicists in the world and become a person who affects the world.

"But physics is not mathematics!" Edward Witten shook his head slightly: "You can have smooth sailing in the field of mathematics, but this is not the case in the field of physics."

"It's much harder to do well in physics than in mathematics."

Edward Witten thinks about his own life. He is a Fields Medal winner and has also won the Einstein Award and the Newton Medal.

But he has yet to win the Nobel Prize in Physics.

It's not that he has poor abilities, but that if he wants to win the Nobel Prize in Physics, he needs to discover something in the field of physics that no one has discovered before.

This is compared with mathematics, which puts problems in front of you and asks you to solve them. If you solve them, you can win the Fields Medal or the Wolf Prize in Mathematics.

In physics, there is no problem in front of you, you need to find and explore.

If you discover something new and it has a great impact on the entire world of physics, you can win the Nobel Prize in Physics.

When it comes to proving difficulty in mathematics and physics, they are equal.

However, in terms of the difficulty of achieving results, low-level and intermediate-level physics are easier than mathematics, and high-level physics is more difficult than mathematics.

"Let me see your capabilities in these two fields, quantum mechanics and general relativity!"

Edward Witten looked at Ye Fei on the stage with great anticipation.

Magic City, International Conference Center!

After Ye Fei walked onto the stage, he glanced at the people in the audience, then put the microphone in his hand to his mouth and said: "Quantum mechanics and general relativity are two great theories in physics."

"But a basic concept is that these two theories are incompatible with each other, and in fact they address two different components of the world, space-time and matter."

"The unification of quantum mechanics and general relativity is also known as the quantum theory of gravity."

"The theory of quantum gravity is a hypothetical theory that combines quantum mechanics and general relativity. It can answer some of our profound questions about the physical world. It is well deserved to be called the Holy Grail of physics."

Offstage!

Many reporters exclaimed: "It turns out that Ye Fei's complete and consistent theory of quantum mechanics and general relativity is a unified theory of quantum mechanics and general relativity."

Although these reporters are not physics majors, as science reporters, they will be exposed to some basic common sense in mathematics, physics and other fields in their work.

In the world of physics, the most famous one is the Theory of Everything, followed by the Grand Unified Theory.

Quantum mechanics and general relativity are one of the grand unified theories.

Tong Siyu said very excitedly: "Sister Yu, Academician Ye Fei is actually talking about one of the grand unified theories, the unification of quantum mechanics and general relativity!"

"With Academician Ye Fei's ability, publishing such an academic report on such an occasion must have required some research."

"We got big news today."

Tong Siyu was so excited. She didn't expect that when she participated in Ye Fei's academic activities for the first time, she would encounter one of the most difficult problems in physics.

Many science journalists may never encounter such an occasion in their lifetime.

Yu Mengmeng nodded slightly and looked at Ye Fei on the stage with a smile on her face.

On stage!

Ye Feidao: "Why do we need quantum gravity theory?"

"In quantum mechanics, matter and fields are in a prepared space-time. In this space-time, space-time itself does not have any physical effect on the field..."

Ye Fei eloquently introduced why we need quantum gravity theory.

"We need to bring in a quantum theory of gravity."

"Because all basic theories about the physical world should be background-independent, as shown by space-time under general relativity, this means that the current quantum mechanical theory is incomplete."

"Because it still requires the assumption of space and time, rather than deducing the existence of space and time from itself like general relativity."

"How should quantum theory and general relativity be unified? What is the focus?"

"This is also what I mainly talk about today."

The scholars present and watching the live broadcast were all excited when they heard Ye Fei's words.

They are very interested in any kind of grand unified theory.

If they prove any grand unified theory, they can become celebrities in the physics world, become the world's top physicists, and win the Nobel Prize in Physics.

Ye Feidao: "Newton believed that time and space are eternal and absolute, and were thoroughly defined as prerequisites for our existence in the world even before he began to describe force and motion..."

“In general relativity, the only thing that matters is what happens on an object’s worldline, or its history.”

"Events arise from intersections with the world lines of other objects and encode the interrelationships between objects."

"The network structure of these basic world lines contains information that describes all events and world lines. The geometric structure of these world lines determines the physical phenomena in the universe."

When everyone heard this, they were confused: "World line?"

This is the first time they have heard the name World Line.

Ye Feidao: "Everyone, please take a look!"

At this time, a grid of human heads composed of many green lines was displayed on the monitors on both sides of the stage.

"The head wireframe simulates the geometry of an interconnected worldline construct."

"Black space does not contain any geometric or spatial information, and any point in it will not interact with any world lines that make up the network."

"This also explains why space is fictitious and the only thing that can define our four-dimensional space-time are world lines."

When everyone heard this, they suddenly realized that Ye Fei was introducing them to the four-dimensional space in a very concise way.

Quantum gravity theory must study four-dimensional space, which is impossible to get around.

Although there are one to ten dimensional spaces, we currently mainly study one to four dimensional spaces.

Quantum mechanics studies space and time, which naturally includes dimensional space, but now it mainly studies four-dimensional space.

Ye Feidao: "General relativity describes how the geometric structure of these world lines constructs four-dimensional space-time..."

“String theory holds that matter is composed of one-dimensional rings, which are defined in ten-dimensional space-time, four of which are the four-dimensional space-time we see. The remaining dimensions are compressed and define the properties of the object itself through their geometric symmetry. , there are still some problems with this quantum gravity theory..."

Ye Fei pointed out some problems with string theory.

Ye Fidao: "The best thing so far is that the loop quantum gravity theory derives the basic principles of string theory."

"..."

“But there’s also a huge problem.”

"Loop quantum gravity theory..."

"One possible explanation is that these extra dimensions are not really space, but just tools for physicists to perform calculations that will eventually be replaced by a full four-dimensional string theory."

The scholars in the audience exclaimed when they heard this. They were shocked by the last words Ye Fei said.

Many people are surprised: "Is this really true? Dimensional space is not a real space, but a tool for calculation that will eventually replace the complete four-dimensional string theory?"

“It’s a bold idea to use space as a tool for calculation!”

"No one has ever mentioned this idea before!"

The idea of ​​using space as a computing tool is very science fiction.

This is just like the wandering earth in Three-Body Problem, it is very science fiction.

Ordinary people would not think about letting the earth wander, nor would they think about using space as a calculation tool.

Many people shook their heads: "What an incredible idea. I wonder how Ye Fei came up with it?"

“Is this an idea that anyone can think of, turning space and time into a tool for calculation?”

When the reporters behind saw these scholars exclaiming, they looked at them blankly.

What are you exclaiming? What's there to exclaim about? Is there any surprising discovery?

These Muggles were itching in their hearts and wanted to know what these scholars were exclaiming.

They knew this was big news.

"Sister Yu!" Tong Siyu said excitedly: "There must be big news here, but we can't understand it. What should we do?"

Yu Mengmeng said calmly: "Don't panic, I will take you to interview Academician Ye Fei later, and he will tell us."

When Tong Siyu heard this, she felt completely at ease. With the relationship between Sister Yu and Academician Ye Fei, she could directly ask Academician Ye Fei if she didn't understand anything.

Ye Feidao: "This is about a theory I created recently, called causal set theory."

"Like loop quantum gravity theory, causal set theory is a background-independent theory of space and time."

Ye Fei then explained the causal set theory in detail.

The causal set theory was created by Ye Fei when he was studying the unification of quantum mechanics and general relativity.

Of course, this causal combination theory was only created to facilitate the unification of quantum mechanics and general relativity by Ye Feirang.

Elsewhere, it's not of much value.

Ye Feidao: "Quantum space-time also involves holographic principles and quantum entanglement!"

The holographic principle is what Ye Fei studied when he studied the metaverse.

"According to the holographic principle, any information and relationships in a three-dimensional space are encoded on the two-dimensional surface surrounding the space, which means that the relationships between surface elements reflect the behavior inside the object."

"But based on what I've found."

"If you use quantum entanglement to connect two points on the surface, the corresponding points inside will be connected to each other as a physical unit."

"If you turn off quantum entanglement at the surface, the correlation of internal points disappears and the internal space becomes uncorrelated points."

"The amount of entanglement can be directly related to the degree of physical proximity between points. This is how quantum entanglement can be used to connect unrelated points within a three-dimensional object to form a unified geometric structure."

"Return to the world line!"

"Through the study of quantum entanglement, we can find that in order to unify quantum mechanics and general relativity, we must use quantum entanglement as a tool to unify quantum mechanics and general relativity across dimensional space."

"If we want quantum entanglement to span dimensions, we must use dimensional space as a computing tool to study it."

"Instead of treating dimensional space as an object of study!"

"Thank you everyone, my speech is over!"
