MTL - The Science Fiction World of Xueba-Chapter 517 Strong interaction materials
"Alin, thank you!"
Shen Yuan looked at the distance and sighed softly.
Pang Xuelin said with a smile: "Teacher, don't think too much, as long as we can accurately locate the sunset on the earth's center, I am confident that the sunset will be rescued from it within ten years!"
Shen Yuan smiled bitterly: "How can it be so easy, even if the positioning is accurate, we have to develop a geo-nuclear spacecraft! Although the existing new solid materials can be used as the geo-nuclear spacecraft shell, this material is too heavy , Using this material to make the shell, our engine can only barely propel it to sail in the mantle, but inside the core of the earth, it is difficult to move! Now we can develop a satisfactory core nuclear spacecraft engine within ten years!"
Pang Xuelin smiled and suddenly said: "Teacher, if the development of the engine is too difficult, why don't we try to reduce the quality of the spacecraft?"
Shen Yuan shook his head and said: "How can it be so easy, the material technology we have, this new solid material can adapt to the high temperature and high pressure environment inside the earth. Others, like carbon nanotube materials, although strong enough, but not High temperature resistance has no effect. The only weakness of the new solid material is that it is too heavy! Even if a high-power fusion engine is used, it can only barely push it forward in the mantle!"
Pang Xuelin said: "Teacher, have you heard of strong interaction materials?"
"Strong interaction materials? Are you talking about neutron materials and quark materials?"
Shen Yuan was slightly startled.
Pang Xuelin smiled and shook his head and said, "No, this substance has the same quality as ordinary substances, but its molecular structure is firmly locked by strong interaction force, the vibration is almost zero, and its strength is even among the new solid materials. Above, but the density is one to two orders of magnitude lower than the new solid materials!"
"Alin, are you sure this kind of material exists in the world?"
Shen Yuan frowned.
The material Pang Xuelin said is beyond the principles of physics he can understand, more like the field of metaphysics.
If another person said so to him, Shen Yuan would have gone away long ago.
But this person was Pang Xuelin who discovered the inert neutrino not long ago, and Shen Yuan had to pay attention.
Pang Xuelin smiled slightly, and the reason why he mentioned strong interaction materials, Pang Xuelin was not a whim.
On the one hand, in the dark forest world, humans have already had a certain idea of the study of strong interaction materials, and even completed the preparation of strong interaction materials in the laboratory.
Humans in the earth cannon world have developed normally until 2075, and various technologies are sufficient to support the research and development of this material.
Pang Xuelin can draw a gourd exactly like this, and find the preparation method of this material in the earth cannon world.
On the other hand, Pang Xuelin is also doing tests.
He wanted to see if in Liu’s sci-fi universe, the essential laws of the universe were consistent.
As long as the basic law has not changed, the various black technologies obtained from Da Liu World can naturally be used for trial.
The material with strong interaction force comes from the water droplets of the three-body civilization detector in the world of "Dark Forest".
In the "Dark Forest" world, Liu's description of water droplets is like this.
[The detector is about the same size as expected. It is 3.5 meters long. When Ding Yi saw it, he produced the same impression as everyone else: a drop of mercury. The detector is in the shape of a perfect water drop. The head is round and the tail is sharp. The surface is an extremely smooth total reflection mirror. The Milky Way reflects a smooth light pattern on its surface, making this drop of mercury look simple and beautiful. The shape of its droplets is so vivid that observers sometimes think it is liquid, and there is no possibility of internal mechanical structure.
"What is its quality?" Ding Yi asked.
"At present, there is no accurate value, only a rough value obtained by high-precision gravimeter, which is about ten tons or less."
"Then at least it was not made of neutron star matter."
"You can only guess." Ding Yi looked up and said, "The molecules of this thing are arranged neatly like an honor guard, and they are consolidated with each other at the same time. Do you know how strong this consolidation is? The molecules are like nails nailed to themselves. The vibrations are gone."
"This is why it is at absolute zero!" Xizi said. She and the other two officers knew what Ding Yi meant: in ordinary density matter, the distance between the nuclei is very large, and they are fixed to each other. It's not much easier than using a set of connecting rods to fix the sun and the eight planets into a set of stationary streets.
"What force can do this?"
"There is only one: strong interaction can be seen through the mask," Ding Yi's forehead was full of cold sweat. 】
Shortly after this conversation took place, the water droplets began the destruction of the joint human space fleet, and the destruction of the human fleet made humans panic unprecedentedly.
A substance that is not in the state of a neutron star, the weight is not very large, the material is still smooth after being enlarged 10 million times, the molecules are arranged in an orderly manner without any vibration.
According to research by scientists in the "Dark Forest" world, this material does not exist under normal conditions.
This has to start with the basic composition of matter.
As we all know, matter is made up of atoms. Atoms can be broken down into nuclei and electrons. The nuclei can be broken down into protons and neutrons. These are collectively called nucleons.
Protons and neutrons can be divided into quarks.
This is the limit so far that humans can break down particles.
Even with geosynchronous orbit accelerators, there is no way for Quark to continue to decompose.
Quarks can combine with each other to form composite particles.
After a lot of research by scientists, it is found that the quark combinations in the universe are generally three quarks to form protons, and the neutron model has not developed four quark, five quark or more quark combinations.
However, we can theoretically speculate the properties of four-quark and five-quark particles.
When a certain distance is maintained between such particles, a strong interaction force can be generated.
Strong, electromagnetic, weak, and gravitational forces are the four basic forces that maintain the order and existence of the universe. These four forces determine the hardness of matter.
If the hardness index given to the substance by electromagnetic force is set to 1, the hardness index given by the weak force and gravity to the substance is almost negligible, while the hardness index given by the strong force is indeed 100.
Scientists in the "Dark Forest" world have discovered that ~www.novelbuddy.com~ Among three-quark protons and neutrons, the strong force only exists inside the protons and neutrons, but for four-quark or five-quark particles, the strong interaction force The effective distance can be increased by one to two orders of magnitude, reaching 10^-13 meters.
In this case, the atoms and molecules composed of four-quark or five-quark nucleons can be firmly locked to form a strong interaction material.
Pang Xuelin explained the general principle of strong interaction materials to Shen Yuan, and Shen Yuan was dumbfounded.
"But, Alin, even if this material exists, where do we go to find the four-quark and five-quark atoms and molecules? Do we use a collider to drive hadrons to collide and try our luck every day? The four-quark and five-quark atoms thus obtained I'm afraid it's just a lot of money."
Pang Xuelin smiled slightly and said, "Teacher, if you asked me to prepare four-quark and five-quark substances a month ago, I am afraid I can't do it, but now, it is not difficult!"
"what do you mean?"
Shen Yuan looked at Pang Xuelin puzzled.
