Chapter 490 The Egg Problem
There was warm applause from the audience.

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

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

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

"This question is not a simple question, but it is impossible to stump me with this question. Well, how about this, I will limit the number, I only accept three questions, and you have to choose the most difficult question." The three questions." Liu Shiyuan said.

Solving this problem is quite simple, but it also takes a lot of thought.

"You can ask them to ask questions about various subjects. I believe you have a deep knowledge of mathematics, but what about other subjects? Can you do other subjects? Physics, chemistry, biology, I am really very worried You." Liu Jiajia said.

"Don't worry, the big deal is losing the game. I will quit the entertainment industry sooner or later. It's the same as quitting early or quitting later." Liu Shiyuan said frankly.

There was a smile on his face, which didn't change at all.

To him it was just a game.

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

"I want to ask whether physics has an end? Have we reached 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.To ask such a question.

This problem is also a problem that troubles many scientists. Many people, including many scientists, believe that physics is approaching the end.

Liu Shiyuan smiled and said: "Many scientists have been exploring whether the process of this universe is approaching the end.

Some scientists said: "I worry that we have reached the limit of empirical science."

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

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

When the apple fell on Niutun's head, he was 25 years old, and then he proposed the law of gravity and developed calculus.Also at the age of 25, Dirac proposed the equations of relativistic quantum mechanics.

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

So Gino Sigre, a high-energy theoretical physicist at the University of Pennsylvania in the United States, encourages young

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

Lots and lots of physicists are working on figuring out what the other 90.00% of matter is.

Every galaxy contains dark matter, and it is this unknown matter that keeps our galaxy from disintegrating.When dark matter gathers to a considerable amount, they collide and annihilate, producing electrons, protons, positrons and antiprotons.The annihilation of dark matter particles in the Milky Way at a rate we can observe will reveal their nature.

However, the discovery of dark energy driving the accelerated expansion of the universe has brought a series of new problems, and it may be difficult to make progress in a short time.These questions include what are the properties of dark energy itself?
Why is it so small for galaxies and stars to form and life to arise in this universe?
We don't know if science has come to an end, but what we do know is that we can keep going. "

In previous lives, this was also an unanswered question.

But in any case, we have to work hard to explore.

Newton discovered classical mechanics, and Einstein discovered 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.

Only then did people rethink whether physics has reached the so-called end.

But in fact, this question is a bit of a dead end.

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

No one may have an answer.

"I don't know if you are satisfied with this answer?" Liu Shiyuan said looking at the student in front of him.

The student stood up and said, "I want you to give me a definite answer, and I think it's a bit unreasonable for you to answer like this."

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

"I think you made a mistake, classmate, what were you talking about just now? And what did you say that you didn't seem confident to listen to? I just said that you must know the answer, and you don't know the answer, so come here Ask me? How would I know? If that's the case, I want to ask you a question, and it's a very simple one.

Do you think the chicken or the egg came first in this world? "Liu Shiyuan said with a smile.

"Really, if you don't listen to the questions carefully, you just rush to answer them. It's a waste of our quota."

"That's right, I trouble you to see the question clearly and answer the question, now people also ask a question, answer it, but this question is really very meaningful.

If there was a chicken first, how did the chicken come about?Didn't it hatch from an egg?

If the egg came first, what lay the egg?Isn't this egg laid by a chicken?

I believe this question is an unanswerable one. "

"Yeah, because until now life doesn't know how chickens evolved into chickens."

Many people are thinking about this question with a sad face.

Which came first, the chicken or the egg?
In fact, this question seems to have no answer, but in fact there is an answer.

Whether it is a chicken or an egg, they all exist at the same time, and there is no order.

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

Many people are concerned about this issue.

There are also live broadcasts of Liu Shiyuan's speech, and many schools are closed to listen to Liu Shiyuan's speech.

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

Zhu Yongjie said: "This question has been debated for a long time, and there has been no clear answer.

In fact, the appearance of eggs is much earlier than that of chickens, because reptiles appeared as early as 8000 million years ago in the Permian period, and birds appeared in the Jurassic period 8000 million years ago. Ji, the chicken appeared even later.

According to the theory of evolution, there is no question of who comes first, the chicken or the egg.

As a species in the class of Aves, chickens are differentiated from primitive birds, and eggs are fertilized eggs of chickens (referring to eggs that can breed chicks). A bridge between generations in the evolution of "primitive birds-chickens".

A "chicken" can lay many eggs, but not all eggs can eventually become adult chickens.

Among them, heredity plays the role of maintaining and consolidating the variation, and the variation is accumulated through heredity.After a long-term process from "chicken" to egg and from egg to "chicken" from generation to generation, under the action of natural selection, the variation of species is accumulated in a targeted manner, resulting in the differentiation of species and the formation of new species. "Chicken" It evolved slowly, and eggs evolved accordingly. This is a process of millions of years, and the order of appearance of "chicken" and "egg" must not be rigidly divided. "
