Strong interaction force materials, of course, Qiao Lu will not be unfamiliar with this, the water droplets that destroyed the human united fleet in the three-body problem are made of strong interaction force materials.

It's just that Qiao Lu never thought that the Wandering Earth could also develop a strong interaction force material, which is a completely different level from the new solid state, how is it made?

Ding Yi saw through Qiao Lu's doubts, and explained with a smile: "To explain this matter, we have to start with what is the strong interaction force, physics believes that the universe has four basic forces, strong interaction force, weak interaction force, electromagnetic force and gravitational force. ”

"The strong interaction force is the force that combines protons and neutrons into the nucleus, and is the strongest of all fundamental forces. Neutrons have no electric charge, while protons have a positive charge, and once combined, they produce a strong electromagnetic force that repels each other, but the strong interaction force overcomes this electromagnetic force and tightly bonds the proton and neutron into the nucleus. If this is a bit difficult to understand, for example, atoms and molecules are held together by electromagnetic forces, except for the protons and neutrons that make up the nucleus. ”

"In the final analysis, the hardness of a substance is determined by the atomic structure and molecular structure, so no matter how hard a substance is, it is essentially caused by the strong electromagnetic force between its atoms and molecules. However, the strong interaction force can be a hundred times stronger than the electromagnetic force, in other words, the strength of the strong interaction force material is hundreds of times higher than the hardest known substance! ”

At present, the hardest matter known to the Wandering Earth, of course, is the vibranium obtained from the Marvel Universe, and the composition of the double-edged war knife and the peerless blade is still incomprehensible, but in essence, as Ding Yi said, it relies on the combination of electromagnetic forces between atoms and molecules, which is hundreds of times weaker than the strong interaction force that allows protons and neutrons to combine into atomic nuclei.

It can be said that this is the difference between a nuclear bomb and an ordinary bomb, TNT is very efficient in explosives, but compared with a nuclear bomb, it can only become a unit of measurement, and it still has to be measured in tons.

This is the case with strong interacting materials, which are already fundamentally different from other materials, and the hardness of any substance is like an egg hitting a stone compared to it.

"Is it really that powerful?" Qiao Lu asked curiously.

Shen Huabei smiled confidently and said, "Of course, do you know why it is a sphere with a smooth surface?" That's not polished, it's just that it can only come out that way. Every atom inside is tightly bound together like protons and neutrons, and even the electrons outside the nucleus are pressed into the nucleus, so to speak, it is a huge nucleus, and the surface is pressed into absolute smoothness by its own gravity, and it is shaped like this from the moment it becomes a strong interaction material. ”

In order to prove this, the staff carefully operated the vibranium knife with a mechanical operation, and slashed it, even scratching out dazzling sparks, but did not leave the slightest scratch on the metal sphere, which was not left at all.

Not only that, the staff also used optical instruments to magnify the cut position 10 million times, to the extent that the macromolecules can be seen, and the surface of the sphere is still smooth and mirrored, and there is no sign of damage.

Smooth surfaces are the most susceptible to scratches, yet even when slashed hard by vibranium, the surface of the metal sphere does not leave any scratches.

Vibranium, an incomparably hard substance, is really about to become a unit of measurement for materials with strong interaction forces!

Qiao Lu couldn't help but take a step closer, wanting to take a closer look at the metal sphere made of this strong interaction material.

Ding Yi warned him: "Don't touch it! Since the molecular vibrations inside are completely gone, the surface temperature is at absolute zero, and even the slightest touch will cause frostbite from it! ”

Such an unreasonable substance is already beyond the scope of Qiao Lu's comprehension, just as human beings felt the power of nuclear energy when they detonated a nuclear bomb for the first time, Qiao Lu also felt that compared with ordinary matter, materials with strong interaction force seem to be not from the same dimension.

"How the hell did you do that?" Qiao Lu finally couldn't help but ask, "It can't be obtained by infinitely increasing the power of a nuclear explosion according to the method of creating a new solid state, right?" ”

Shen Huabei replied: "The first few steps are indeed the same, using 'sugar coating' to wrap the metal material, and then relying on a nuclear explosion to further compress it to obtain a new solid material with ultra-high density. ”

"But then we fell into a bottleneck, on the one hand, the stress that the outer layer of nanomaterial 'sugar coating' can withstand is not infinite, so it is impossible to increase the power of the nuclear explosion all the time, when it reaches a certain nuclear explosion yield, the sugar coating will be damaged first, resulting in the inability to further compress."

"On the other hand, as the new solid matter is further compressed, the electromagnetic repulsion between the protons will become greater and will not be able to get close to each other to a certain extent. The strong interaction forces can only act at extremely short distances inside the nucleus. Therefore, if the repulsion of the electromagnetic force cannot be overcome and the two atomic nuclei are pressed tightly together, there is no way to make a material with strong interaction force. ”

Just as the closer two magnets get together, the greater the magnetic force generated between them, the electromagnetic force further increases as the atoms are compressed, resulting in the new solid state being unable to be compressed into a strong interacting material.

In this case, the external pressure is either further increased and the atoms are forcibly bonded together by the interference of electromagnetic forces.

However, the scope of the external force of the "sugar coating" is not unlimited, and this road is no longer feasible.

The other way is to find a way to weaken or even eliminate the electromagnetic force, and I'm afraid that's the only way.

"So we took advantage of the Power Gem you brought back." Ding Yi went on to explain:

"At first, we had no idea what the Power Gem could be used for losing energy, although it could absorb energy, it was not absorbed quickly and could not be used as a defensive weapon. Until we discover that it can absorb a certain kind of energy, opening the door to a new world for us on a microscopic level. ”

I see, now Qiao Lu understands how they further compress the new solid state into a strong interaction force material, electromagnetic force is of course also a kind of energy, as long as it is energy, it can be absorbed by the power gem, and there is no need to absorb it very quickly, as long as the interference of electromagnetic force is slowly eliminated, the strong interaction force material can be made naturally.

It is worthy of the most powerful object in the Marvel Universe, the Infinity Stone, and even if it loses its infinite energy, it is still a priceless treasure.

This is really an unexpected gain, Qiao Lu didn't expect that the power gem could have such an effect!
