Qu Nanxiu went to the hospital to visit Professor Luo with a large bag of health care products, and when he entered the door, he happened to hear two little nurses chatting with the professor.

It is said that this morning, someone saw a cat jumping from the high-traffic Fourth Ring Road viaduct, and I don't know how it climbed there.

Witnesses were driving by, but they didn't see the results, and now they don't know.

One nurse said, "It's so high, and there's traffic down there, if you don't fall to death, you will be crushed to death." ”

Another said, "Not necessarily, doesn't it mean that cats have nine lives?"

The first nurse laughed at her: "You are also a college graduate, why do you still believe this?"

"Yuan Fang, oh no, Professor Luo, what do you think about this?"

Luo Renyan, who was bored and half-lying on the hospital bed, laughed: "It may also be that the cat is both alive and dead, in a superimposed state of living and not living." ”

After hearing this, the two little nurses froze with sunny smiles on their faces, looked at each other, and silently packed up their things and went out.

The heart says that he is an academician of the X Academy of Sciences and a great professor, and he is actually at this level, isn't it embarrassing to say it!

Only Qu Nan, who had just entered the door, understood that Professor Luo was talking about "Schrödinger's cat".

"Schrödinger's Cat" is a thought experiment proposed by the famous Austrian physicist Schrödinger.

Simply put, put a cat and a bottle of poison gas in a box. There is a 50% chance that the gas will be released to kill the cat, and a 50% chance that the gas will not be released and the cat will survive.

According to classical physics, one of these two outcomes is bound to occur inside the box, and an outside observer will not know the outcome inside until the box is opened.

However, in the quantum world, as long as the box is closed, the whole system has been in an uncertain wave state, that is, the superposition of cat life and death.

This experiment aims to demonstrate quantum mechanics' unreasonable knowledge and understanding of the world of microscopic particles, and that cats are both alive and dead, contrary to logical thinking.

If the box is opened and the cat is still alive and able to speak, wonder how it can describe the strange feeling of life and death?

There were only two people left in the ward, Luo Renyan and Qu Nanxiu.

Professor Luo said: "Actually, I happened to think about this famous cat recently. ”

Xiaoqu said: "Now your main task is to rest, don't keep thinking about it and waste your brains." ”

Because of the long-term use of liquid food, Luo Renyan has lost a lot of weight, and the little belly that was more troublesome before has gone down a large piece, he said helplessly: "Anyway, there is nothing to do here all day long, and it is dark when you are full, and if you don't turn your brain, you can only wait for death." ”

"And what do you think of?"

"Schrödinger's cat is either alive or dead, so to speak, the moment you open the box, time and space suddenly split into two, one is the cat is dead, and the other is the cat is alive. If these two planes continue to exist independently of each other, and there is a you in both worlds. These two you may do different things and go to different destinies. Then before the spatial fission, that is, before you open the box, these two space-times are superimposed, and the cat's life and death are a probability. ”

"So what?"

"If you add other parameters, for example, if the cat is alive, whether it is standing or sitting, and if it is dead, whether it is lying on its stomach or lying down. With the addition of these four possibilities, four parallel universes are created – standing alive, sitting alive, lying dead, and lying on their stomachs. And so on other factors, and so on, we get an infinite number of parallel universes. ”

If the two little nurses heard this, they would definitely have to take Luo Renyan's temperature to see if they had a high fever and were talking nonsense.

Fortunately, with Qu Nanxiu's knowledge and understanding of Professor Luo, he was still able to understand: "So the conclusion is?"

"I'm not at the conclusion yet, but I have to talk about multidimensional space. As we all know, one-dimensional space is a line, two-dimensional space is a plane, three-dimensional space increases height, and four-dimensional space is three dimensions with time added. If you distort the four-dimensional space so that any two points touch each other, it becomes a wormhole that can be traversed, like a random door, you can go from one place to any place in an instant. ”

The song was listened to with great interest.

Don't look at Professor Luo's life and don't listen to much speech, but he is never boring when he teaches knowledge, on the contrary, it is concise and interesting, and the more people listen, the more addictive they become, which is definitely a kind of talent.

"The fifth dimension is a four-dimensional space with countless possibilities. In the five-dimensional space, you will see countless four-dimensional trajectory diagrams of the same person, each trajectory diagram is his life, he may become a painter, a teacher or a salesman...... So what if you distort space in five dimensions? Let's say, twist somebody's five and fifty years together?"

"He's going to suddenly go from five to fifty?"

"Yes, that is to say, people in the five-dimensional space can change their age at will. ”

Qu Nanxiu thought that if there was really a five-dimensional space, the people inside would definitely be younger and more beautiful than the other, because no one wanted to get old.

However, when he was a child, he was too naïve and delicate, and he preferred his current self. If he could really change his age at will, he felt that his current age would be good.

"On the basis of the five-dimensional space, the six-dimensional space adds a variety of possibilities. What happens if you warp the six-dimensional space?"

Qu Nanxiu pondered: "If any two points in the six-dimensional space are touched, can it be said that you can change your age and destiny at will?"

"Clever! You can become tall and short, fat and thin, poor and rich, and become all kinds of occupations at will, so the six dimensions are a collection of all possibilities. There are seven dimensions, from our universe to another universe, eight dimensions, the collection of possibilities of different universes, nine dimensions, the universe that can be changed at will, and ten dimensions: everything and everything...... That's the difference from one dimension to ten dimensions. ”

"Well, but Professor, why do you think of this in such a good way?"

"Because of you. ”

"Me?"

Luo Renyan looked at Xiaoqu with wise eyes: "Yes, I've been wondering, are you different from us somewhere?"

Qu Nanxiu was at a loss for the second monk when he heard someone knocking on the door. It was the peak time for hospital visits, and it was normal for someone to knock on the door.

Qu Nanxiu went to open it, and then he and the comer each let out an exclamation.

"Ah, Xiaoqu!"

"Ah, Xiao Que!"

"Don't come unharmed!"

"It's like a lot of autumn!"

Xiao Que is one of the few beauties who makes Qu Nanxiu not appreciate her as the opposite sex. Although she is also good-looking and attractive, she feels more like a brother who can talk to.

The two exchanged pleasantries in surprise for a long time, and Xiao Que remembered apologetically that he had come to visit Professor Luo on behalf of the TV station's science and technology program team.

There are not too many things to say, that is, the few words that people often talk about when they visit patients, Xiao Que and Xiao Qu have a lot to say, so when she left, Qu Nanxiu went to send it.

"Xiao Que, I see that you are smiling, you should have been doing well lately, right?

"Troubles, as long as you work in the station for a day, as long as you live for a day, there will definitely be something. But it's true that there are some happy things. ”

"Tell me to share?"

"Actually, it's nothing, I'm getting married. ”

"Congratulations, great joy! and whom?"

"Thank you, hehe, it's still the same as before, reconciled. ”

"Oh, the one you said looked like me?"

"That's right, that's right, you have a pretty good memory, and he's got your hairstyle recently, the two of you are exactly the same, the only difference is that he's not as tall as you, oh, and this Hongji or Hong's triceps aren't so big. ”

"Gee, I want to meet him. ”

"No problem, he's waiting for me downstairs in the hospital. His name is Liu Yu, and I'll take you to meet him to prove that I'm not lying!"

We often hear people say in our lives that someone looks like whom, but most of them are just gods. It's really exactly the same, and it seems that only twins can barely reach it, so Xiaoqu didn't have much hope, so he should get to know more brothers.

But but, when he saw Xiao Quan's boyfriend up close, he was really stunned!

Liu Yu is a few centimeters shorter than Qu Nanxiu, although his figure is not so good, his broad shoulders support his clothes, and his style looks no different from Xiaoqu.

What's even more exaggerated is that the outlines of the facial features of the two are printed in duplicate as if they were printed out by a photocopier, is it just one person?

Xiaoqu was stunned, could Liu Yu be his long-lost brother?

But I've never heard my dad mention it for so many years, and I and my dad have nothing to talk about. It's impossible for grandma not to mention a word about such a big thing.

The two of them widened their eyes, you look at me, I look at you, as if they were looking in the mirror. But the person in the mirror is dressed differently from himself.

This is a wonderful feeling, which reminds Qu Nanxiu of the first time he "saw" Tu Tian, you have me, I have you, doing what he does, feeling his mood.

Suddenly, he had a magical idea, but he thought it was too ridiculous, so he gave up again.

Liu Yu was obviously unprepared and surprised, but quickly stretched out his hand to him.

The two hands were clasped together, as if a person was shaking hands with himself.

Xiao Que said proudly beside him: "What's the matter, I'm not exaggerating, right? I think you two can quickly bow down!"

How can you bow down because you look alike? I don't know anything about my temperament and temperament. Besides, there is no peach orchard!

Qu Nanxiuxiu's brain turned around, and he remembered what to say: "Oh yes, I heard that the two of you are about to get married, congratulations." ”

"Thank you. ”

Xiao Que raised his eyebrows and said, "Hey Xiaoqu, otherwise when we get married, how about you come to be the best man?"

Liu Yu smiled: "Don't, it shouldn't be clear who is the groom and who is the best man at that time, what if you enter the wrong cave room?"

Xiao Que said angrily: "Tsk, what are you talking about?"

Liu Yu smiled again: "But I'm really surprised, we look so similar, we have to have a meal together to get to know each other." ”

Xiaoqu, who is born to make friends, said, "Okay, let's go." ”

The two of them hooked their shoulders and lifted their feet and left, forgetting that there was still a person behind them, and Xiao Que shouted behind him: "Hey, wait for me!"
