Due to the time difference of nearly twelve hours between the Northern Riteure Kingdom and the Xia Kingdom.

Therefore, when Xia Guo held the academic report, the academic report of Beili had not yet begun.

Therefore, at this moment, many people around the world are watching the Modu Academic Report in the metaverse.

For this academic report, the international mathematical community and the physics community are full of attention.

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 fields of study play a very important role in mathematics and physics, respectively.

North Beauty, in a small cottage near Princeton University!

On the sofa against the wall in the study of the small villa, a white-haired white old man with a high hairline was lying.

His name is Edward. Witten, a Jewish physicist and mathematician in Northern Korea, a Fields Medal-winner, a professor at the Institute for Advanced Study in Princeton, and a leading scholar in string theory and quantum field theory.

He was once evaluated by the Beili "Life" magazine as the sixth most influential person in the world after 1945.

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

The H-index is a hybrid quantitative indicator that can be used to assess the number of academic outputs of researchers versus the level of academic output.

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

Although many scholars are capable, the number of papers published is very small, resulting in the H-index not matching their own ability.

For example, Ye Fei, Yang Zhenning and some others.

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

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

As the person with the highest H-index in the physical world today, Edward. Witten's ability can be imagined.

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

Newton, Einstein, and Maxwell belong to the first tier.

Galileo, Faraday, Pol, Planck, Heisenberg, Dirac, Schrödinger, Yang Chenning and Rutherford belong to the strong second bracket.

Landau, Pauli, Feynman, Marie Curie, Weinberg, Edward. Witten, Higgs, and the rest of the twenty or thirty people belong to the weak second grade.

Ding Zhaozhong, Kao Kun, Lee Tsung-dao, Nanbu Yoichiro...... It belongs to the third grade.

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

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

It is conceivable from this that Edward. Witten is great in the world of physics.

Of course, the premise is that the theoretical research is confirmed, and if it is not proven, he belongs to the weak second grade.

Edward. Witten wore virtual glasses, lying on the sofa, watching Ye Fei on the stage to start speaking.

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

"If the Landau-Siegel zero-point conjecture can prove successful, it seems that he will have a place in next year's Wolf Prize in mathematics, and he will also be among the top mathematicians in the world."

Edward. Witten didn't pay much attention 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, the rest of the mathematical research will not be paid attention to by him.

Edward. Witten looked at Ye Fei on the stage, looking forward to it: "I don't know if Ye Fei can have any new research in the field of quantum mechanics and relativity." ”

For Ye Fei, who has become famous in recent years, Edward. Witten takes it very seriously.

Especially after Ye Fei developed the metaverse, Ye Fei's prestige reached its peak, and many people said that Ye Fei would be the greatest scientist of the 21st century.

For this, Edward. Witten was not convinced.

If Ye Fei wants to become the greatest scientist of the 21st century, he must first pass my hurdle.

If he can't surpass me, he will never want to be the greatest scientist of the 21st century.

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

He has studied 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 unity of quantum mechanics and general relativity.

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

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

The theory of all things is a combination of many grand unified theories.

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

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

"It's very difficult, and since the time of Einstein, there have been countless physicists who have studied it, and there is still no eyebrow."

"Ye Fei wants to prove the unity of quantum mechanics and general relativity, which requires him to study all his life."

If a physicist can prove one of the grand unified theories, he will become one of the world's greatest physicists and a figure who will influence the world.

"But physics is not math!" Edward. Witten shook his head slightly: "You are smooth sailing in the field of mathematics, but not in the field of physics. ”

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

Edward. Witten thought about his life, he was a Fields Medalist, and he also won the Einstein Medal and the Newton Medal.

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

It's not that he is incompetent, but if he wants to win the Nobel Prize in physics, he needs to discover things in the field of physics that no one has discovered before.

This is compared to mathematics, which puts a problem in front of you and asks you to solve it, and you can get a Fields Medal or Wolf Prize in mathematics if you solve it.

Physics, on the other hand, is a topic that you need to look for and explore.

If you explore something new and have a great impact on the entire physics community, you will win the Nobel Prize in Physics.

To say that the difficulty of proof in mathematics and physics, they are equal.

However, it is easier to make a grade in low- and intermediate-level physics than in mathematics, and higher-level physics is more difficult than mathematics.

"Just let me see what you can do in the fields of quantum mechanics and general relativity!"

Edward. Witten looked at Ye Fei on the stage expectantly.

Magic City, International Conference Center!

After Ye Fei walked on 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 fundamental notion is that these two theories are incompatible, 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 theory of quantum gravity."

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

Offstage!

Many reporters exclaimed in their hearts: "It turns out that the complete and consistent theory of quantum mechanics and general relativity that Ye Fei said is a unified theory of quantum mechanics and general relativity. ”

Although these reporters do not study physics, as science reporters, they will be exposed to some basic knowledge in mathematics, physics and other fields in their work.

In the world of physics, the most famous is the theory of everything, followed by the theory of great unity.

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

Tong Siyu said excitedly: "Sister Yu, Academician Ye Fei actually said one of the great unification theories, the unity of quantum mechanics and general relativity!" ”

"With Academician Ye Fei's ability, there must be some research to publish such an academic report on such an occasion."

"We've got big news today."

Tong Siyu was so excited, he didn't expect to be able to encounter one of the ultimate problems in the physics world when he participated in Ye Fei's academic activities for the first time.

This kind of occasion may not be encountered by many science journalists in their lifetime.

Yu Mengmeng nodded slightly, looking at Ye Fei on the stage, her face full of smiles.

Stage!

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

"In quantum mechanics, matter and fields are in a preparatory space-time, in which space-time itself has no physical effect on the field......"

Ye Fei introduced why we need the theory of quantum gravity.

"We need to introduce the theory of quantum gravity."

"Because all the basic theories about the physical world should be context-independent, just like space-time under general relativity, this means that the current theory of quantum mechanics is incomplete."

"Because it still needs to presuppose space-time, rather than deducing the existence of space-time from itself, as general relativity does."

"How should quantum theory and general relativity be unified? What's the point? ”

"That's what I'm going to talk about today."

The scholars present and watching the live broadcast all came up with their hearts when they heard Ye Fei's words.

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

If any of the grand unified theories are proved, they can become celebrities in the physics world, become the top physicists in the world, and also win the Nobel Prize in physics.

Ye Fei said: "Newton believed that time and space are eternal and absolute, and even before he began to describe force and motion, he was thoroughly defined as a prerequisite for our existence in the world......"

"In general relativity, only one thing is concerned with the events that occur on the line of the object's world, or its history."

"Events arise from intersections with the worldlines of other objects, and encode the interrelationships between objects."

"The network structure of these basic worldlines contains information that describes all events and worldlines, and the geometry of these worldlines determines the physical phenomena in the universe."

When everyone heard this, they wondered: "World line? ”

It was the first time they had heard of the name World Line.

Ye Fei said: "Everyone, please take a look! ”

At this time, the displays on both sides of the stage show a grid of human heads composed of many green lines.

"The head wireframe simulates the geometry of the interconnected worldline construction."

"Black space does not contain any geometric or spatial information, and no point in between it interacts with any of the worldlines that make up the network."

"This also explains why space is imaginary, and the only thing that can define our four-dimensional space-time is the world line."

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

The theory of quantum gravity must study four-dimensional space, which is impossible to bypass.

Although there are 1 to 10 dimensional spaces, we are currently mainly studying 1 to 4 dimensional spaces.

Quantum mechanics is the study of space-time, which naturally includes dimensional space, and now mainly studies four-dimensional space.

Ye Feidao: "General relativity describes how the geometry of these worldlines constructs a four-dimensional space-time ......"

"The string theory that matter consists of one-dimensional rings that are defined in ten-dimensional space-time, of which there are four dimensions that we see as four-dimensional space-time, and the remaining dimensions are compressed, defining the properties of the object itself through their geometric symmetry, and this theory of quantum gravity still has some problems......"

Ye Fei pointed out some problems with string theory.

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

“……”

"But there's still a huge problem."

"Loop Quantum Gravitational Theory ......"

"One possible explanation is that these superfluous dimensions are not really space, but merely tools for physicists to make calculations, which will eventually be replaced by full four-dimensional string theory."

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

Many people were surprised: "Is that really the case?" Dimensional space is not really space, but a tool of computation that will eventually replace a full four-dimensional string theory? ”

"What a bold idea to use space as a tool for calculation!"

"This idea has never been mentioned before!"

The idea of using space as a computational tool is very sci-fi.

This is like the wandering earth in the three-body problem, which is very sci-fi.

Ordinary people don't think about letting the earth wander, nor do they think about using space as a computing tool.

Many people shook their heads in their hearts: "It's really an incredible idea, I don't know how Ye Fei thought of it?" ”

"Is it an idea that people can think of to turn space-time into a tool for calculation?"

When the reporters in the back saw these scholars exclaiming, they all looked at them blankly.

What are you exclaiming? What is there to exclaim? Is there anything surprising about it?

The Muggles were tickling in their hearts, wondering what the scholars were exclaiming.

They know that it must be big news.

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

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

When Tong Siyu heard this, his heart completely settled down, too, with the relationship between Sister Yu and Academician Ye Fei, if you don't understand, you can directly ask Academician Ye Fei.

Ye Fei said: "This is going to talk about a theory I recently created, called the theory of causal sets. ”

"Like the theory of circumferential quantum gravity, the theory of causal sets is a context-independent theory of space-time."

Ye Fei then explained the theory of causal sets in detail.

Causal set theory was coined by Ye Fei when he studied the unity of quantum mechanics and general relativity.

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

The rest of the place, it's not worth much.

Ye Feidao: "Quantum space-time also involves the holographic principle and quantum entanglement!" ”

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

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

"But according to what my research has found."

"If quantum entanglement is used to connect two points on a surface, the corresponding internal points will be connected to each other as a single physical unit."

"If quantum entanglement of the surface is turned off, the correlation of the 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, which is how to connect unrelated points inside three-dimensional objects to form a unified geometric structure through quantum entanglement."

"Return to the World Line!"

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

"If we want quantum entanglement to transcend dimensions, we need to study dimensional space as a computational tool."

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

"Thank you, and that's the end of my speech!"
