Liang Jingjing looked at Xu Yunzhi, she was a little hesitant. She became a monk halfway through, knowing that she was not a qualified scientist, so she did not dare to express her scientific opinions casually: "I don't know if it is a harvest ......"

"Let's talk casually, it's not a formal academic point of view!" Xu Yunzhi encouraged her.

"Okay......" Liang Jingjing took a sip of wine, as if to cheer herself up: "I browsed the history of science on the earth and found that the twentieth century was a great era, but it was also a ......"

Liang Jingjing was halfway through speaking, and then hesitated a little.

"Why don't you say it?" Xu Yunzhi couldn't get the following, so he urged: "Say it! ”

"I think the twentieth century was a great era, when scientific theories developed explosively, giving rise to the theory of relativity, quantum mechanics and so on......," Liang Jingjing hesitated again and again, and finally said: "But it was also a fatal era, and the development direction of scientific theories seemed to have begun to detour at that time." ”

"Your judgment is a bit fresh," Xu Yunzhi said, "Let's hear it." ”

"How to say it...... Liang Jingjing fixed his mind and said: "In that century, the theory of relativity and quantum mechanics appeared, science and technology developed rapidly, and soon entered the electronic age from the industrial age and then into the information age, but ...... Since then, however, fundamental physics research has come to a standstill......"

"No," Xu Yunzhi said, "many high-tech products appeared in that era, such as computers, mobile phones, and quantum colliders. And space technology, what satellites, space shuttles, space stations, and so on. ”

"That's right, but those that I think are just developments in the practical application of these theories, that is, horizontal developments. However, theoretical research is only a tinkering with the original theory, and there is no breakthrough development. ”

"Jingjing is really not easy!" Xu Yunzhi said sincerely: "The era of eating old books...... You continue! ”

"I'm a class leader, Professor Xu don't laugh at me......" Liang Jingjing said.

"How could it be! Jingjing, to be honest, I admire you very much! Xu Yunzhi said sincerely: "When everyone felt that the future was bleak and one day at a time, you never gave up." Everyone can see your hard work, otherwise, I will make you the vice president of the Academy of Sciences, how can everyone agree without an opinion! ”

In this regard, Liang Jingjing did not express an opinion. A few days ago, Xu Yunzhi said that when he was busy with work and needed to promote a vice president, no one cared; When Xu Yunzhi proposed to let Liang Jingjing take the position, everyone had no opinion. But Liang Jingjing knew that at that time, the catastrophe had not disappeared, and everyone felt that the future was bleak, and they didn't know how long they could live, so it didn't matter if they were vice presidents or not.

But now, it's really hard to say what others think about this result! So she avoided this: "Okay, I drank a lot of today anyway, so I'll take advantage of the wine to talk nonsense!" ”

She begins with the debate between Einstein and Bohr and talks about the Copenhagen interpretation: "You have just shown with an example how much the argument between the two of them will benefit the development of quantum theory. But their arguments have led proponents of the Copenhagen interpretation to constantly look for new ways to justify their theories, such as epistemology, thermodynamic irreversible processes, decoherence theory, and so on, to find a defensible theoretical support for wave function collapse. The most ridiculous thing is ......"

"Come, take a sip of wine to moisten your mouth first!" Seeing that Liang Jingjing became more and more excited, Xu Yunzhi hurriedly asked her to drink and breathe a sigh of relief.

"The most ridiculous thing is," Liang Jingjing drank and continued, "In addition to the efforts to correct the collapse of the wave function, some physicists do not agree with the idea of the collapse of the wave function and try in every possible way to come up with other theories to replace it." In the end, even some parallel universe came out, which is really brain-blowing, but can it be regarded as rigorous scientific research? ”

Xu Yunzhi smiled, of course she knew that the initiator of this theory was called Everett. And then it was constantly developed, and finally it became a popular theory. This is the most sought-after new theory of quantum physics by science fiction fans - the theory of many worlds.

As you can imagine, there are countless worlds where you are. From the day you were born, from the moment your first cry was heard by others, you have constantly divided the world into countless branches, so that all the people in the world have to follow the doppelganger, they have to live with you in this different world, and you have to constantly replicate yourself in the world that others have divided...... This is the cosmic wonder that theories such as parallel universes and multiverses paint for you.

If you believe in this theory, it is very beneficial, because it is called "quantum immortality"! According to this theory, wave function collapse never occurs. That is, every possible state of the wave function will develop and will not disappear because of your observations, and each state needs a world for it to develop, so it needs an infinite number of parallel worlds.

Blessed are those who believe in this theory, as you only need to do a double-slit electron interference experiment, and the universe will split into countless parallel universes. In this way, the world was not created by God, but we human beings, and we human beings are constantly creating new universes every moment! For the sake of a small electron landing problem, we human beings have the ability to involve the division of the entire universe and split countless parallel universes!

What's even more jaw-dropping is that according to this theory, we can easily deduce the strange theory that a person will never die. In the process of splitting, you have been killed in this world, but you are still living in another, if not countless other parallel worlds. There is only one God, and "quantum immortality" makes you more awesome than God!

"Ridiculous, isn't it?" Seeing Xu Yunzhi smile, Liang Jingjing also smiled: "This scientific theoretical research, how can it be almost theological while playing?" ”

"But this great controversy of the century has indeed promoted the perfection of quantum theory!" Xu Yunzhi said.

Liang Jingjing said: "But that is also a prison drawn, which makes the theoretical research of fundamental physics in a dilemma." For more than 30 years, Einstein turned to the grand unified theory in order to resolve this disagreement, in order to reconcile the contradiction between the theory of relativity and quantum theory. But nothing was gained as a result. Since then, there has been a superstring theory, but this theory needs at least ten dimensions to establish a theoretical framework that makes gravity and quantum mechanics compatible, otherwise it is a theory that can neither be falsified nor proven......"

"Extra dimensions are an integral part of string theory," Xu Yunzhi said: "The mathematical equations of string theory require that space is 9 dimensions, plus the time dimension is a total of 10 dimensions of space-time. Further research shows that a more complete understanding given by the M theory reveals the 10th dimension of the string theory, so that the maximum dimension of the theory is 11 dimensions. ”

"Where are those dimensions?" Liang Jingjing said: "Some people say that it is curled up, and we can't see it. How to curl it, who curled it up? Where did you put the other dimensions that were curled up? You can't say, roll it up and put it in my pocket, right? ”

"In fact, in the end, the world has also confirmed that theory is theory, and even if it can be logically self-consistent, it may not help reality at all!" Xu Yunzhi was amused: "When quantum theory first appeared, some people said that it was likely to be the ultimate theory, and the superstring theory was also thought to be very likely to be the ultimate theory, but in fact there was none. But human society is inevitably in trouble, and even human survival has become a problem! ”

That's why I said. It was a great era, but also an era that went wrong and planted a curse! Liang Jingjing said: "What parallel universe, what 11-dimensional space, playing and playing, they all play like Lord Newton, and sooner or later they will play the first push!" ”

"The one you said is really funny," Xu Yunzhi also said, "Since there is an 11-dimensional space, why do you expand our 3-dimensional plus time-dimensional space and curl up the rest of the dimensions?" The high dimension should contain the lower dimension, not the other way around. Now that the higher dimensions are curled, the space of our 3-dimensional plus time dimension, which is supposed to contain it, has been expanded separately? ”

"So, the theoretical study of fundamental physics has become a theoretical game of fundamental physics, what can it be said that this is not a crooked path?"

"Have you studied superstring theory?" Xu Yunzhi asked.

"I studied it a little bit," Liang Jingjing said, "but I think it's definitely wrong, it's a directional mistake." Jones Lulu said that everything in the universe is simpler and more stable, that is, the road is simpler. If it becomes more and more mysterious, it is certainly not the right direction, even if it is philosophically logically self-consistent. ”

"Huh! Jingjing does have some ideas," Xu Yunzhi said, "and she is very assertive." ”

"I can't help it!" Liang Jingjing said: "Life is too short, and it would be a pity if we wasted our limited time." I think we should learn from Jones and be as sensible as possible. If you look at what they do, you know that they are very practical, so they can run so far and keep their race going. ”

"It's a pity that we know very little about their technological development paths......"

"Professor Xu!" Liang Jingjing suddenly asked, "Have you been looking at the piece of skin cut off my brother's body recently?" ”

"Nope!" Xu Yunzhi said: "What's wrong? ”

"It's long!" Liang Jingjing said mysteriously: "It seems to have grown up!" ”

The wine glass in Xu Yunzhi's hand fell to the ground with a "bang".

"Of course, I don't know if I'm wrong......" Liang Jingjing said as she bent down to pick up the wine glass that Xu Yunzhi had dropped: "Maybe I'm wrong, it's actually like that." ”

Liang Jingjing said that she was going to get a new wine glass for Xu Yunzhi again, but Xu Yunzhi stopped her: "Let's go and have a look!" ”

"It's too late today, why don't you go tomorrow?"

Xu Yunzhi couldn't wait, so he pulled Liang Jingjing and left. The piece of skin cut from Shu Yunpeng's arm was only the size of a fingernail, and they used some of it when they were researching. This piece of skin originally had the characteristics that surprised Xu Yunzhi very much, and it was not rotten without any antiseptic treatment. Now Liang Jingjing said that it would grow up automatically, which surprised her too much.

They hurried to the laboratory, and Liang Jingjing took out the vessel where the skin was placed. It was a sealed vessel, and when sealed, the air inside could be drained, and the vessel became a vacuum. Although this skin is miraculously not rotten, Xu Yunzhi still uses vacuum preservation for the sake of insurance.

Xu Yunzhi carefully observed the piece of skin with a high-powered magnifying glass, and carefully measured the diameter of the skin. It's rare, but it's a bit bigger.

"When did you find it grown?" Xu Yunzhi observed for a long time and asked.

"It's been a few days," Ms. Liang said, "but then it hasn't been long...... I think it has something to do with the preservation method. ”

"Why do you say that?" Xu Yunzhi was surprised: "Haven't you always put it here?" Is it ......?"

"It's been in this sealed vessel," Liang Jingjing said, "but after I used it that time, I didn't seal it properly, and when I opened it a few days later, I found that it seemed to have grown up." ”

"Then you sealed it, and you found that it didn't grow long, did you?"

Liang Jingjing nodded, and Xu Yunzhi smiled.

"So after thinking about it, you think that this skin will grow, and it will only happen under certain ecological conditions! You'd love to keep it in an unsealed environment to see if it does what you think it is? ”

"Yes, I don't dare to decide ...... on my own"

"So you deliberately invited me to drink today, just to tell me this?" Xu Yunzhi laughed: "Cunning and cunning! ”

"Actually, it's not just this......" Liang Jingjing blushed slightly and smiled: "I also think that since it can grow, it means that it is active." If you add some nutrient solution or something, will it grow faster? ”
