Chapter 385 Projection of gravitons

"So, this is it."

The gravity of relativity, and the gravity of multidimensional field theory.

He only needed to make a few changes to the gravity of the multidimensional field theory, and found that the two formulas were so similar that he could not even make any difference.

Then, after some simple transformations, the two equations can be connected with an equal sign.

"Is this a coincidence in physics?"

Lin Xiao couldn't help but admire in his heart.

This is equivalent to the fact that the theory of relativity and quantum mechanics, which were once almost completely incompatible with the discussion of gravity, can now be connected with an equal sign.

Of course, although they are connected, the physical meaning contained in them still needs to be discussed.

Although now Lin Xiaoda can directly publish the equation he accidentally discovered, and he also believes that this is just a "Physical Review Letters" and can easily set off a wave of articles in the physics community.

However, with Lin Xiao's character, he would not allow himself to publish it without even understanding its meaning.

Looking at this equation and the formulas on the left and right, Lin Xiao pinched his chin. How to find out the actual physical meaning from mathematical symbols is a relatively common thing for an excellent physicist. After all, they are originally It means using mathematics to discuss physics. If they cannot understand the physical meaning, it will obviously bring certain obstacles to their research.

However, for Lin Xiao, seeing the meaning behind it is not the most critical thing. The most critical thing is whether he can proceed with more deductions after seeing the meaning.

And at this moment, that's exactly what he was doing.

Looking at the equation in front of me, although both sides of the equation are harmonious, no matter what, as a person who has done in-depth research on physics, I was pleasantly surprised by the equation that the theory of relativity is actually related to graviton. It's just awkward. Of course, it's out of habit, not the kind of awkwardness that feels wrong.

Just like that, after carefully observing this equation, Lin Xiao raised his eyebrows slightly and had some ideas.

General relativity includes the classic Newtonian law of gravity within the framework of special relativity.

In the general theory of relativity, gravity is described as a geometric property of space-time, that is, curvature, and this curvature of space-time is directly related to the matter in space-time, and its connection method is Einstein's field equation.

"So, Einstein's description of gravity in the theory of relativity is as presented by this Einstein field equation."

[Gμv=Rμv-1/2gμvR……]

Lin Xiao wrote this Einstein field equation on paper. The equation is very simple, but the various meanings contained in it are not simple at all.

"This is based on the definition of gravity under general relativity, and according to multi-dimensional field theory, various dimensions are superimposed, and gravity... gravity..."

Lin Xiao groped his chin, but his eyes became brighter and brighter.

He suddenly felt like he had completely simplified this problem.

"Just like the current description of gravity under general relativity in the physics community, an extremely heavy matter presses a pit in the large network of space and time, and then other matter around this extremely heavy matter will begin to circle around this The pit surrounds it.”

Just like what is shown in the videos describing gravity on the Internet, there is an elastic cloth, and then a big ball representing a star is placed on it, and the big ball presses out a pit, and then drops it from the edge. A few balls representing planets were added, and these balls representing planets began to circle around the big ball representing stars.

"But obviously, in our world, space and time are three-dimensional, and stars are also three-dimensional, so it is impossible for three-dimensional stars to press out a large net on three-dimensional space and time. But if gravity affects our three-dimensional space and time from a four-dimensional perspective, What effect does it have?"

"And in fact, this view has always existed in academia."

That is to say, gravity should belong to the four-dimensional space, not the three-dimensional space where they are located, so they cannot observe gravity in the three-dimensional universe.

"But how can gravity interfere with our three-dimensional space from a four-dimensional perspective? Is there something in the middle that connects these two things?"

At this moment, Lin Xiao already felt that he was very close to the key.

"Contact...contact..."

Lin Xiao suddenly had a bold idea in his heart.

"Maybe, gravitons are like this?"

He began his deduction again.

This time, he integrated the particle that is very similar to the graviton predicted in the standard model of multidimensional field theory.

Integration is the inverse operation of derivation.

Derivative is the differentiation of the original function, and integration is to find the original function.

At this time, what Lin Xiao has to do is to find the original function of the graviton in this three-dimensional space.

This is a slightly complicated indefinite integral problem. Of course, in Lin Xiao's hands, this complexity can be turned into simplicity.

And with the completion of this step, he saw an astonishing result.

The graviton after integration, let's call it the graviton in four-dimensional space, is actually related to his previous equation.

Lin Xiao's eyes showed surprise, and then he felt relieved.

"So, the gravity in three-dimensional space is actually the shadow of the four-dimensional graviton in four-dimensional space..."

"And the thing that looks like a graviton that I predict in the standard model of multidimensional field theory is its shadow."

The tone of his statement meant that he was certain of the result.

Just like the shadow of a person, it is a projection of a three-dimensional object onto a two-dimensional one, while the projection of a four-dimensional object is naturally projected onto a three-dimensional one.

"It's just that because it involves high-dimensional particles, it makes our observation difficult."

"Then, that's a good solution."

A smile appeared on Lin Xiao's face.

Once, he used low dimensions to peek at high dimensions, but now, he has even found the connection between high dimensions and low dimensions.

At the same time, it is also conceivable that what other particles also belong to this kind of projection?

Lin Xiao can easily think of one, that is neutrinos.

After all, neutrinos are difficult to observe, elusive and difficult to detect.

"Okay, let's not talk about this anymore. Let's sort out the papers first."

It just so happened that it once again brought an important result to his multidimensional field theory.

Although his multidimensional field theory has been around for a few years, there are not many people who have studied it, but there are not many major results like this.

Therefore, it is up to him, the founder, to drop another depth bomb to make this water active again.

…

"Physical Review Letters" is famous for its fast review speed, especially the speed of rejection.

Of course, when the person submitting the paper is a famous physicist in the world, they receive it very quickly.

Therefore, when Lin Xiao's paper was submitted, the editorial department quickly completed the review. First, they were amazed by the content, and then published the paper, which amazed them all, in their download. in one issue of the journal.

"Physical Review Letters" is mainly famous in the physics community for its short length and important content. In short, most of the papers are relatively short and concise, so there are many physicists who subscribe to it.

When Lin Xiao's paper was seen by physicists, the entire theoretical physics community exploded.

Connecting relativity and gravitons? Still follow the standard model of multidimensional field theory?

Gravity is the product of four-dimensional space in three-dimensional space? The gravitons in their universe are the projection of gravitons in four-dimensional space?

These words that sound very science fiction are not science fiction at all in Lin Xiao's paper, and those science fiction words basically come from their physics community.

Therefore, Lin Xiao's paper made all physicists feel crazy.

But from a mathematical point of view, no one doubts its correctness.

After all, Lin Xiao's deductions are all rational and orderly inferences, rather than based on additional theories for perfection. Just like the description of gravitons in the Standard Model, the physicists who originally determined the Standard Model originally intended to It was introduced to improve the model.

As a result, heated discussions started in the physics community, with many famous physicists, especially some Nobel physicists.

"I have to admit that every paper written by Professor Lin is so amazing. As a physicist who studies quantum mechanics, I support Professor Lin's results."

"In any case, Professor Lin's paper still opened up a possibility for us. I think we are now one step closer to the final answer to gravity. As for what the final answer is, it naturally depends on us. In the collider, I saw the fleeting gravitational interaction force. 』

"Oh, my God, the two people upstairs are actually Nobel Prize winners. It really gives me a lot of experience!" As a PhD student in physics, I can only tremble. Of course, no matter what, Professor Lin will always be my idol."

"Professor Lin is still very powerful. He has made such significant achievements in multi-dimensional field theory. It feels like Einstein's theory of relativity. Einstein almost single-handedly developed the theory of relativity to the same level as quantum mechanics." level, and Professor Lin is doing such a thing now, right? 』

"That's true, even though I can't even understand one of Professor Lin's papers."

Among the many comments, many people maintained high evaluations of Lin Xiao's paper. However, in these speeches, a refutation of relativistic physics appeared, and this relativistic physicist was also a well-known physicist. Although he did not win the Nobel Prize, he did not win other heavyweight awards in physics.

"Hey, no matter how fanciful you say, I can't imagine the existence of gravitons. Although Professor Lin connected the existence of gravitons with the theory of relativity, from another perspective, wouldn't this still make Is the theory of relativity completely broken down? 』

Of course, other physicists also responded to the famous physicist's remarks: "Oh! Old Jike, you can't think like this. Now we just draw an equal sign, but in the future we won't be able to find a perfect way to make the theory of relativity and gravitons more harmonious? After all, they are all connected now. Just like when you are chasing your wife, you take your time. You need to connect first, and then slowly get closer."

"My wife and I met in a bar. After we got drunk together, we were done with it. There was no slow process of getting closer like you mentioned."

"..."

In this way, more and more physicists discussed this matter. In the end, physicists who studied quantum mechanics believed Lin Xiao's results very much. However, for those physicists who studied relativity, they Although they approved Lin Xiao's paper, they still said that they were still unwilling to believe the result without experimental results to prove it.

As for the experimental results they want to see, it is naturally to directly or indirectly observe the existence of gravitons in experiments.

And this is also the most critical point in this matter.
