Chapter 189 Ambitious

In this report, this group of top scientists compares the Super Hadron Collider to "the key to the door of truth"!

"It is a crutch on a rugged road, a bridge to the other side, and the best window to peek into the universe..."

"Without it, human particle physics theory will stop at the current level and never make any progress!"

"...The mysteries of the universe will be fully displayed in the hadron collider!"

This project report is certainly not a trick, all the data and content are real, without any exaggeration.

Yu Yifeng's temples throbbed wildly, and he clearly felt the ambition of the new human civilization at this moment.

Yes, an ambition to yearn for science!

There is no doubt that these top scientists are the outstanding representatives of civilization. Their will can even represent the will of the entire civilization. The group of scientists, who occupy the majority of the total population, are the main group of the new human civilization.

They want to explore the unknown and explore the endless mysteries of the universe!

And the best way is-hadron collider.

However, Yu Yifeng is very cautious. As a leader for such a long time, he habitually thinks over and over again and analyzes the pros and cons. He can't let his head get hot and hot because of a few ambitious words of encouragement.

It is good to have such an ambition, but his only consideration is... the cost is really too high! Whether it is material resources or human resources!

Can modern humans really afford to build this thing?

He looked at Yuriko and wanted to hear her opinion.

Yuriko thought for a long time this time and finally analyzed the pros and cons. Of course, the specific judgment still had to be made by Yu Yifeng himself.

"Our science has basically completed the standard model, but it does not mean that science will stop there. Although the standard model looks excellent, it is not perfect, and it still cannot describe gravity."

"Moreover, the particles described by our current standard model are less than 5% of the particles in the universe. In other words, 95% of the particles are unknown to humans. This is also the main reason for building this super-large LHC. We want to discover unknown particles and understand them through this large instrument, and then improve our model and understand the entire universe."

Yu Yifeng nodded. He knew all these common sense things.

He looked at Yuriko, waiting for her to continue.

"At present, we are looking for particle physics models that are better than the standard model, and supersymmetry theory is one of them, and it is also one of the most promising ones."

"Because it looks very perfect and elegant. If supersymmetry theory can be verified, it can tell us why particles have the current mass, why interactions produce different intensities, and why the universe is like this now?"

"Then, we can further explore string theory, improve M theory, and so on..."

"For all this, perhaps only the super hadron collider can bring us inspiration. Without it, our theoretical science will be difficult to progress, which is very likely..."

Yu Yifeng touched his chin. He deeply understood the scientific significance of the Large Hadron Collider.

For science, experiments are very important. Without experimental verification, all discussions are just fantasies.

Of course, if the experimental verification fails, then the entire theory fails, and there is no room for negotiation.

Science is very realistic and cruel. Whether it is right or wrong, the universe is there, and it will not change because of your research or your fantasy.

Yuriko paused, and this time she was silent for a long time again.

She said in an unexpectedly dull and depressed tone: "The Earth's LHC did not find supersymmetric particles, and rejected a large number of low-energy models. This is a very disappointing thing. So, we either completely abandon the supersymmetric theory, or... we can only explore models with higher energy scales."

"Higher energy scales mean more powerful instruments and higher funding requirements, but even so, we may not be able to explore anything. It is just a hypothesis, not necessarily correct... However, the hadron collider on Earth and experiments with higher energy scales are difficult to meet."

"So, the hadron collider we are going to build may be a key for humans to knock on the "door of the universe", but it may also be, and more likely - a black hole that no one knows when it will produce a return. Worse, maybe everything is a scam of our fantasy and the universe."

"... Even, we will never be able to discover other particles through it! Everything is in vain!"

"All our efforts may be in vain..."

Yu Yifeng was silent. The failure of the low-energy supersymmetric theory was a big blow to people like Yuriko, and even to Ding Yidong, Felix, Rambo and others.

Everyone thinks it is perfect, so much so that scientists around the world have been working on it for thirty years or even longer.

The theory of supersymmetry has almost become a belief, a religious piety, and countless scientific papers are based on this assumption.

If it is completely wrong, then... these painstaking papers will become waste paper.

If it is correct, the Nobel Prize is just a small matter, and it is completely insufficient to describe the achievement.

But no one knows whether this path is correct. It is very likely that after all the effort, people will sadly find that this path is blocked.

The universe is always like this, like a shy girl, she never easily reveals the truth hidden in her clothes...

"It would be great if the supersymmetry of low-energy scale is correct..."

.

Yuriko said in a low voice, and it was obvious that she was hit hard by that experiment.

How easy is it to surpass the classics?

Humans have been trying to use a set of theories to understand the laws of the entire universe from the most microscopic level.

In current particle physics, the most outstanding model is called the "standard model". In the 21st century, the discovery of the Higgs boson completed the last missing piece of the puzzle for the standard model.

The "standard model" is a theory that describes the three basic forces of strong force, weak force and electromagnetic force and the basic particles that make up all matter.

So far, almost all the results of experiments on the above three forces are consistent with the predictions of this theory. It is indeed excellent and is the crystallization of the wisdom of countless scientists from generation to generation.

However, the standard model is not a universal theory, it does not describe the entire universe. The main reason is that it does not describe gravity.

So the standard model is only partially applicable, it is not completely correct...

Every scientist knows that it is not completely correct, only partially, which brings a greater desire for exploration.

Just like Newton's classical mechanics, it is limited to macroscopic low-speed objects; macroscopic high-speed objects are applicable to relativity; microscopic objects are applicable to quantum mechanics...So the most intelligent scientists in the world, these smartest brains, will never be satisfied with "partial correctness".

They are eager to go beyond the standard model, eager to overthrow it, and eager for a more correct and more magnificent theory.

Such a fantasy theory is called the "grand unified theory". Scientists are eager to unify all the four basic forces and find the ultimate theorem of all things.

Supersymmetry theory was once regarded as an important candidate for the "grand unified theory", but...

"It has not completely failed, there will always be models with higher energy standards!"
