The audience remembered the warm applause.

They all understood that the reason why Liu Shiyuan is doing this today is because he still has an identity, which is the dean of the School of Mathematics at Kyoto University.

After Liu Shiyuan's explanation, the topic was finally figured out.

Before I figured it out, it was a very simple question, but after I figured it out, it was a very simple question.

"It's not an easy topic, but it's impossible to stump me with just that. Okay, why don't you do that, I'll limit the number, I'll only accept three questions, and you have to pick the three most difficult questions. Liu Shiyuan said.

It's quite easy to solve this problem, but it takes a lot of thought.

"You can ask them to come up with problems in all kinds of subjects, I'm sure you have a deep knowledge in mathematics, but what about other subjects? Can you do the other subjects as well? Physics, chemistry, biology, I'm really worried about you. Liu Jiajia said.

"Don't worry, the big deal is to lose the game, I will quit the entertainment industry sooner or later, early exit and late exit are the same." Liu Shiyuan said calmly.

With a smile on his face, he didn't change at all.

In his opinion, it is a game.

It's just that there is only one person on his side, and countless people on the other side.

"I want to ask if there is an end to physics? Are we at the end of physics? A student asked such a question.

Liu Shiyuan looked at this young man and felt that this young man was very promising. Asking such a question.

This question is also a problem that plagues many scientists, and many people, including many scientists, believe that physics is nearing the end.

Liu Shiyuan smiled and said: "Since many scientists continue to explore whether the process of this universe is nearing the end.

Some scientists say, "I'm afraid we've reached the limits of empirical science." ”

He wondered if it was necessary to know other universes in order to understand why our universe was the way it was. If these realizations are unattainable. Perhaps this is the end of the process of further deepening our understanding of this universe.

People are accustomed to seeing the progress of theoretical physics as some kind of accident, and whether there is a way to accelerate our understanding and discovery.

He was twenty-five years old when the apple hit Niutun's head, and then he came up with the law of gravity and developed calculus. Also at the age of twenty-five, Dirac proposed the equations of relativistic quantum mechanics.

It was also at this age that Heisenberg gave the matrix form of quantum mechanics.

Therefore, the high-energy theoretical physicist of the University of Pennsylvania in the United States. Sigray encourages the young

It is now clear that ordinary matter atoms, stars, and galaxies occupy only four percent of the entire universe.

Numerous physicists are trying to figure out what the remaining 96 percent of matter is.

Every galaxy contains dark matter. It is these unknown substances that have saved the galaxy we inhabit from disintegrating. When dark matter gathers in a significant amount, it collides and annihilates, producing electrons, protons, positrons, and antiprotons. The dark matter particles in the Milky Way are annihilating each other at a rate that we can observe, which will reveal their nature.

However, the discovery of the dark energy that drives the accelerated expansion of the universe has brought a new set of problems, and it may be difficult to make progress in the short term. These questions include what are the properties of dark energy itself?

Why is it so small that galaxies and stars can form and life can appear in the universe?

We don't know if science has come to an end, but what we do know is that we can keep moving forward. ”

In a past life, this was also an unanswered question.

But no matter what, we have to work hard to explore.

Newton discovered classical mechanics. Albert Einstein discovered the theory of relativity.

At that time, many people thought that physics had come to an end.

But the subsequent discovery of quantum mechanics broke people's cognition.

People are rethinking that physics has not reached the so-called end.

But in fact, this problem is a bit of a percussion.

Whether we reach the end or not, we have to continue to explore.

Whoever it is, there may not be an answer.

"I don't know if you're happy with this answer?" Liu Shiyuan looked at the student in front of him and said.

The student stood up and said, "I want you to give me a definite answer, and I don't think it's reasonable for you to answer like that." ”

He looked around with a smile, as if he had defeated Liu Shiyuan.

"I think you're mistaken, classmate, what were you talking about? And what I said, don't you seem confident to listen to it? I was just talking about it. It has to be you who know the answer, and you don't know the answer. Just ask me? How do I know? If that's the case, I'd like to ask you a question, and a very simple one.

Do you say that in this world, there came first with chickens or eggs? Liu Shiyuan said with a smile.

"It's true, if you don't listen to the questions well, you rush to answer them, it's a waste of our places."

"Yes. Excuse me, you can see that the question is answering, and now people are also asking a question, let's answer it, but this question is really very meaningful.

If there were chickens first, how did the chickens come about? Isn't it hatched from the inside of the egg?

If there is an egg first. What is the egg that lays? Didn't this egg be laid by a chicken?

I believe this is a difficult question that I cannot answer. ”

"yes, because life still doesn't know how chickens evolved into chickens."

Many people are thinking about this with a sad face.

Did the chicken come first or the egg came first?

In fact, this question seems to have no answer, but in fact there is an answer.

Whether it's a chicken or an egg, they are all present at the same time, in no order.

Of course, this is from a biological point of view.

A lot of people are concerned about this issue.

There are also people who are live streaming the scene of Liu Shiyuan's speech, and many schools are closed to listen to Liu Shiyuan's speech.

But at this time, an expert came out to answer this very interesting question.

Zhu Yongjie said: "This question is a question that people have been arguing for a long time and there has been no clear answer.

In fact, eggs appeared much earlier than chickens, because reptiles appeared as early as 280 million years ago in the Permian, and birds appeared in the Jurassic period 180 million years ago, and chickens appeared even later.

According to the evolutionary point of view, chickens and eggs do not have the question of who comes first and who comes later.

As a species in the class of birds, chickens are differentiated from primitive birds, and eggs are the fertilized eggs of chickens (referring to eggs that can breed chicks), and in the long process of the formation of chickens, they have always been a bridge connecting the generations in the evolution of "primitive birds-chickens".

A "chicken" can lay many eggs, but not all of them end up as adult chickens.

Heredity plays a role in maintaining and consolidating variation, and through guò heredity it accumulates. After a long-term, generation-to-generation process of "chicken" to egg and egg to "chicken", under the action of natural selection, the variation of species is accumulated in a directional manner, resulting in the differentiation of species and the formation of new species, "chicken" slowly evolves and is formed, and eggs also evolve, which is a process of millions of years, and must not be divided into the order of "chicken" and "egg".
