"Let me guess, are you Lin Yi?"

The girl shook her head, blinked her big curious eyes, and looked directly at Jiang Chen. Pen & Fun & Pavilion www.biquge.info

If you dye the straight and smooth black hair into silver, and match her with a red contact lens, the appearance of the girl in front of her will be no different from Lin Ling.

"Okay...... Who are you?"

"Number 1004. The girl replied quickly.

Number 1004? Even the name has been omitted.

Jiang Chen smiled bitterly and rubbed her head to express comfort.

The girl felt the sympathy in the eyes of the man in front of her, but she showed a confused expression about the sympathy itself. Apparently she did not understand the reason for this sympathy, or rather, she did not think that the absence of a name was something worthy of sympathy.

"Want a name?" Jiang Chen asked, looking into her eyes.

The girl shook her head, then suddenly raised her head, as if she had received some kind of signal, and turned and ran.

Looking at the direction in which number 1004 had left, Jiang Chen stood up straight and looked at the newly built research institute behind the courtyard.

As early as ten days ago, this research institute was completed, and Lin Ling's sisters had already moved in. Because she was very satisfied with the design of the institute, Lin Ling took the largest laboratory for herself, and then moved the experimental equipment that had been piled up in her room.

As a result, she finally has a spacious bedroom.

In order to facilitate Lin Ling, the construction party opened a small door between the backyard of the villa and the front yard of the research institute according to Jiang Chen's requirements. In addition to Lin Ling, who would pass through that small door every day, her younger sisters would occasionally sneak into the backyard of the villa, staring at the flowers and plants in a daze.

As for why Jiang Chen is standing here, he has to start from two days ago.

……

The time goes back to two days ago, that is, on the fourth day of the fifth month.

Kirwin called from the ground command and reported good news to him. The A-1 successfully returned home after heading for UFO reconnaissance, found no signs of life activity on the target vehicle, and successfully brought back a sample from the aircraft.

Although the sample has not yet been delivered, the relevant data on the sample has been transmitted back to the ground command center. However, to the bewilderment of many experts and scholars, the density of that sample reached a terrifying 2,985 grams per cubic centimeter.

His intuition told Jiang Chen that he had picked up something terrible.

In fact, there was no need to tell him intuitively, and Hawking, who participated in the extraterrestrial civilization research project, directly told him that this discovery was likely to subvert the understanding of matter in modern physics. No other element can form a substance with such a terrifying density and stable existence.

Since modern science couldn't explain it, Jiang Chen immediately turned his gaze to the future.

After asking Kerrwin to pack all the data, Jiang Chen traveled back to the end of the world and casually threw the USB flash drive containing S-class secrets to Lin Ling.

After getting these data, Lin Ling completely locked herself in the laboratory and did not move for two days. Seeing that she was so serious, Jiang Chen didn't bother her, she stayed here in the last days for the past two days, and would come to the backyard every morning and evening to walk around.

At this moment, he saw Lin Ling's figure at the door.

The little girl seemed to have not slept all night, and was now coming towards him with Hatche.

"It's finally done...... Wait, did you do something to my sister?" Lin Ling, who was still tired, suddenly woke up as if she had been electrocuted, and looked at Jiang Chen who was standing in the backyard with a suspicious expression.

"How is it possible!, am I such a beast......" Jiang Chen Khan said.

Lin Ling answered this question with her eyes and said vigilantly, "I warn you, the research field of number 1004 is related to space theory, and it is my assistant in the experimental project of carrying living creatures through the experiment. You are not allowed to indoctrinate her with strange thoughts. ”

"Okay, you'll be bleeding as soon as you meet...... How's that, do you figure out what that little ball is?"

Lin Ling shook her head and said with a sigh.

"At 2,985 grams per cubic centimeter, the density is 2,985 times that of water at room temperature, far exceeding the 22.6 grams per cubic centimeter of osmium, the densest metal in nature, do you know what that means?"

"What does it mean?" Jiang Chen immediately asked.

"At 59 grams per cubic centimeter, that's the density of the red dwarf star closest to the solar system, but it's less than a fraction of the ball on the information you gave me. This means that the interaction force between the particles in that ball is even more terrifying than the gravitational pull of a red dwarf star on its own components. This force has gone beyond the van der Waals force, and if you are not mistaken, there is only one possibility. ”

"What is possible?" Jiang Chen asked in a daze.

"Strong interaction. That small ball is a material directly composed of countless hadrons, and even quarks......" When this conjecture was proposed, Lin Ling's expression was indescribably strange, as if he doubted his guess on the one hand, but was extremely convinced on the other.

"Did there be any technology for this before the war?" Jiang Chen asked.

Lin Ling glanced at Jiang Chen with an idiot-like look, "How can there be such a thing." Until the pre-war period, there was a great deal of controversy in the scientific community about the possibility of materials with strong interacting forces. You're asking if there's any technology for that?"

He had long been accustomed to Lin Ling's poisonous tongue, and Jiang Chen didn't bother to talk to her at this time, so he spread out his hands and said cheekily, "Didn't I ask you if I didn't understand." Smart Miss Lin Ling, can you explain it to me? If that ball is a strong interaction material, then how many years is it higher than the pre-war level of technology?"

Still without resistance to the praise, the corners of Lin Ling's mouth bent proudly and patiently explained to Jiang Chen.

The so-called strong interaction force refers to the force acting on the hadron, which is essentially the interaction force between the quarks that make up the hadron. As the strongest of the four fundamental forces of the universe, its range is only 10 to the minus fifteenth power, beyond which the strong interaction force will decay sharply.

If the particles in the material are composed of strong interacting forces, this means that the spacing between the particles must be within 10 to the minus fifteenth power, unless the atoms are forcibly disassembled and all electrons are discarded. However, this leads to another problem: materials with strong interaction forces that completely discard electrons will have a very large positive charge, which will attract a surprising number of electrons, which in turn will destroy their particle structure.

From the point of view of modern physics, the material itself is an irrational existence.

As for the future.

Who has a good say about the future?

The development of science itself is a process of constant fantasy, constant practice, and constant self-denial.

As for the civilization that has mastered the materials of strong interaction, how many years ahead of the pre-war level of science and technology is this, this Lin Ling cannot give an evaluation, and the development of civilization can never be measured simply by time.

However, there is only one thing that Lin Ling can be sure of, that is, from the understanding of particle physics alone, the gap between the two sides can be described as the difference between cloud and mud. (To be continued.) )
