"So, what is this?" Lin Youde looked at the terrifyingly complicated sketch in front of him and asked the genius who was guarding next to the sketch.

After the physicists looked at each other, Bohr shook his head and stepped forward, taking on the important task of explaining: "This is an imaginary space detection device. ”

"I can still understand the text at the top of the drawing, I want an explanation, what can it do? After all, the cost of this thing is enough to build a large city of more than a million people out of thin air on a wasteland. Lin Youde's voice was steady, he glanced at Sissi, who came to serve as a guard, who was staring at the estimated cost column on the design drawing, and only after noticing Lin Youde's gaze did he turn his face away.

The other two pregnant gods were completely unfocused, sitting on the chairs next to them, happily eating the snacks prepared by the institute in advance—as if Viola had become a foodie after becoming pregnant, as if she had been infected by a fox.

Bohr coughed lightly, "Sir, that's exactly what we're going to do." First of all, let's start with imaginary spaces, whether Dirac came up with the concept of imaginary spaces, or was he inspired by you? ”

"Me?" Lin Youde raised his eyebrows, he didn't remember anything he had done that could inspire this group of epoch-making geniuses.

Dirac stepped forward, stood beside Bohr, and said to Lin Youde: "You once told me a fantasy story about mankind sending stars back from the future world through time travel, so that the mass of the universe can reach a perfect value, so that the universe will neither collapse after expanding to the limit, nor will it expand infinitely and eventually become infinite, becoming a dead and silent dark domain. ”

"Ah, this." Lin Youde remembered that it was a certain time when the fox was being tested, and he waited next to him and felt bored and told a story to Dirac, the main line of the story was inspired by Robert Sawyer's "Constellation", "What's wrong with this story? And now this concept that you have proposed......"

"That's right," Bohr once again took on the task of explaining, "and there has always been an absolutely impenetrable barrier between science and magic techniques. This barrier is made up of two conservation laws, the conservation of mass and the conservation of energy. Of course, these two conservations can be unified together by the mass-energy conversion formula, so they are actually a conservation law. As long as this conservation law cannot be broken, there will always be a clear distinction between magic techniques and science. ”

"yes, I understand." Lin Youde hurriedly nodded, because he always felt that in the future, he might not understand at all, and if he didn't seize this opportunity, he wouldn't have a chance, so he quickly showed his scientific literacy, "The energy of Shen Ji and Zhan Ji can't explain the origin at all, and the energy that drives the magic guide equipment is simply generated out of thin air." ”

"That's right! From a scientific point of view, Shen Ji and Zhan Ji are like the second type of perpetual motion machines, which should not exist at all. ”

"Well," Lin Youde nodded like pounded garlic, "violates the second law of thermodynamics." ”

"No, I'm just making an analogy," Bohr realized that he didn't give Lin Youde face after speaking, after all, Mr. Lin's "new love" was present, he glanced at Sissi, and changed his words, "But you're right, the second law of thermodynamics does violate the second type of perpetual motion machine ......"

The fox laughed.

Lin Youde looked helpless, these geniuses would make such a mistake...... Sissi, on the other hand, looks like she doesn't care about herself.

Lin Youde said: "Keep going. ”

"Uh, yes." Bohr regrouped, "You have given us the task of describing the magic technique with scientific theories. So, this barrier is something that we have to break through. ”

Lin Youde didn't speak, he listened with a serious expression, and Sissi seemed to be a little hesitant, after all, the next content seemed to be something that she, an outsider, shouldn't listen to.

But Bohr continued to explain, "We have come up with many hypotheses over the past few years, and Miss Chihiro has done many tests for this. ”

"I'm going to help too." Viola protested dissatisfiedly, "though less than a fox." ”

"Yes, you also helped." Bohr hastened to add, "However, we have not made much progress in these efforts, and although we have concluded some laws in the magic technique, the barrier is still strong, and we see no hope of breaking through it, until you tell Dirac this story." ”

Lin Youde thought to himself, am I so awesome with this story...... It's a pity that Robert Sawyer, and his "Constellation of Stars", Lin Youde is just a porter of nature.

However, anyway, Robert Sawyer will not be born for decades, so let him Lin Youde temporarily take the glory that should have belonged to the master.

"One thing I found in your story." This time, Dirac, after all, was the one who listened to the story and was inspired, "You said that human beings have broken through the conservation of mass through time travel and successfully increased the mass of the universe. But judging from your description, the time travel in the story is not the same as that of science fiction now, where the impact of travelers is all included in the 'definitive history'. ”

The general time travel story, what the traveler did after going back in time, leads to a change in the future. But there is a genre of time travel storytelling where the whole story has a single, unchanging timeline, and what the time traveler does is already included in this timeline.

A common scenario in this type of time travel story is that A plans to go back in time to save his best friend B, only to find out that it was his own rescue that killed B.

And "Constellation" follows this line of thought when it comes to time travel.

Dirac continued: "In this story, the future and the past can actually be seen as parallel existences, they can be seen as interconnected rooms, and the so-called passage of time is nothing more than the process of us people moving from one room to the next. If you look at it this way, the behavior of human beings in the story to send stars to the past did not break the conservation of mass, they just sent stars from one end of this chain of time houses to the other, and from the perspective of the entire timeline, the mass still remains unchanged. ”

Lin Youde opened his mouth wide, he watched "Star Cluster" several times, and this was the first time he realized this: yes, the mass has not increased, and the conservation has not been broken.

Dirac, this guy, just listened to his Lin Youde's shoddy simplified version of the story, and found out about this!

"But this has nothing to do with us...... Ah......" After all, Lin Youde has read so many science fiction novels, and his thinking is very lively, "I understand, the humans in my story think that the mass has increased and the conservation of mass has been broken, because they can't observe the existence of another 'time house'!" So they mistakenly think that the conservation of mass is broken! ”

"Yes, that's it." Dirac looked excited, "The reason why we feel that the Divine Queen and the Battle Queen have violated the law of conservation of mass and the law of conservation of energy is because we can only observe the range that we can observe, and those energies come from places in this world that we can't observe. When I came up with this idea, I first talked to Planck......"

"Yes, I had the privilege of being the first to hear that idea." Planck raised his chin, a movement that made the glasses on the bridge of his nose gleam, "and then I immediately thought of the mathematical concept of imaginary numbers. People who have long loved mathematics have been thinking about the practical significance of imaginary numbers, but unfortunately, we have not yet discovered what the role of imaginary numbers is in the field outside of mathematics. But! ”

The volume of the "but" that popped out of Planck's mouth suddenly increased a lot, startling Lin Youde, and then Planck raised his right hand, pushed the glasses on the bridge of his nose with his index finger and middle finger, and announced loudly: "Mathematics is perfect!" Therefore, everything that exists in mathematics should have practical significance! There is no such thing as uselessness in mathematics! ”

When Planck said this, the aura he exuded instantly controlled the entire room, allowing Lin Youde to actually experience what is called the aura of a tyrant, and the physics geniuses beside him had the feeling of being a fierce general under the command of a tyrant in an instant.

"So," Planck said again in a suave tone, "imaginary numbers are also meaningful, and I think their meaning lies in that space that we don't currently observe." Let's call that space imaginary space. ”

Lin Youde nodded, indicating that he understood.

At this time, Bohr raised the beam again: "Now you should understand what this thing is for, right?" We believe that through the observation of microscopic particles, we can get a glimpse of the true face of imaginary space to a certain extent. ”

"But how do you make sure it can observe imaginary space?" Lin Youde asked.

"We can't guarantee it." Bohr put it bluntly, "If we don't actually build it and try it, we will never know if it will be able to accomplish the task we have given it." ”

"Okay," Lin Youde nodded, "make it." ”

"When we designed it, we thought about what it would do if it failed," said Pauli, who had never spoken, "and this facility will be of great help to our research in areas such as electronics and radar." ”

"yes, that's better, I've decided to build it anyway." Lin Youde shrugged, then changed his relaxed tone and asked the group of scientists, "Is there anything else?" ”

The scientists looked at each other and eventually shook their heads together.

**

After leaving the research center, the fox shouted that he wanted to take a walk back to the main hall of Sanssouci Palace, but Lin Youde couldn't resist it, so he agreed.

On the way back to the palace, Fox and Viola walked in front, and Lin Youdexisi followed behind.

Sissi suddenly took the initiative to speak: "You can talk to those weirdos so openly, and you can also inspire them......"

"I'm amazing, right?" Lin Youde asked proudly, his thick skin shining in the July sun.

Sissi glanced at him, sighed, and then admitted, "Yes, you are very good, there is nothing to question about this. ”

Lin Youde raised his eyebrows, thinking to himself, is this the meaning of accidentally gaining a little favorability from Sissi?

He immediately tried to expand the results of the battle, but no matter what he said, Sissi only responded on a businesslike basis, leaving him no flaws.
