Next to the name is a special indication of civilization level: 0.85. In other words, their civilization level is much higher than that of Earth in 2090. Although the difference is only 0.11 grades, the power in it is increased exponentially.

Ruan Lin once again carefully flipped through the map, and the minimum level of civilization marked was 0.7! That is, this is a threshold, and civilizations that do not reach it are automatically ignored, and they do not deserve to be recorded on the map of galaxies.

Combined with the previous intelligence, a civilization that reaches level 2.5 can control more than a dozen star systems, so it can be concluded that the overall civilization level of the galaxy is not high.

Ruan Lin felt a chill when he thought of this: Didn't the Zero-Returning Civilization make a move to wipe out civilization millions of years ago? Why are there still so many civilizations in the galaxy?

The Earth reached a civilization level of 0.73 as early as 2015, why hasn't a single civilization ever connected with the Earth?

It was as if the solar system had been ignored. Combined with what the pioneer civilizations said before:

Ruan Lin stopped thinking about the problem, and it was impossible to arrive at the truth from his own imagination alone.

Thinking about it, there are about 300 billion star systems in the Milky Way, of which there are only more than 300 intelligent civilizations, and there are at least 500 intelligent civilizations before the arrival of the Zeroer civilization, and the Drake equation can now have an answer.

Ruan Lin came back to his senses and continued to order: "Wit, continue to carry out research on atoms, and we must find out what binds them together. ”

This external protection technology is at least much more reliable than particle shields, does not require a lot of standing energy, and is very cost-effective.

Research on atomic surface materials has been going on for a year, and the method of eliminating electromagnetic forces between particles in three-dimensional graphene is still unknown.

Through further research, Ruan Lin found that when you zoom in infinitely to observe it, the density of three-dimensional graphene on the surface is equivalent to the density of a neutron star!

If it weren't for the appearance of the "atom", Ruan Lin believed that there was no absolute white body in reality, and the actual object could only be more or less close to the white body.

The reflectivity of the atomic surface γ=1. That is, all laser, radiation type weapons, no matter what power, will be perfectly diffuse reflected when fired at it.

The substance that makes up the atom is just ordinary three-dimensional graphene, and the power of this same kind of civilization is that it can "shoot bows and arrows to the moon", the most understandable way to say is that they added a buff to three-dimensional graphene.

With the buff, even ordinary steel can have a similar effect!

As long as you can master this force, you can pinch the object into a more desirable shape, and the more advanced the tools and processes, the more exquisite the product can be.

For example, mirrors made of copper in ancient times are not as good as modern processed metals. In some metal fittings, the workmanship is so delicate that two flat surfaces can be fitted to each other without detecting the gaps with ultrasound, which is impossible for even the most delicate craftsman to do by hand.

After another half a year of research, Ruan Lin can finally conclude that this force is a strong interaction force, which is the force acting between hadrons, which is the strongest of the four basic forces known to the universe, and the strong interaction overcomes the strong repulsive force generated by the electromagnetic force and tightly binds the protons and neutrons into atomic nuclei.

Inside the "atom", there is a device that can generate a strong interaction force, which binds the protons and neutrons in the three-dimensional graphene on the surface.

From a relatively small point of view, the dust-sized particles are arranged neatly and tightly connected like a guard of honor, the gaps separated by them are extremely small, and the surface of these particles is extremely smooth and flat.

At the femtometer scale, the strength of the strong interaction force is 10³⁹ times that of the gravitational force.

Ruan Lin hurriedly began to study the "strong interaction force generation device", the specific principle of which is not yet known, if further conclusions can be drawn, the basic theory of strong interaction force will add bricks.

WIT also built a laboratory on the outside.

Ruan Lin had some ideas for the fabrication of this device: the strong interaction force, from the point of view of physics, refers to the force that transmits the interaction between quarks through the medium of gluon. It consists of hadrons formed in quarks – the nuclear force between protons and neutrons.

In other words, the transmission of the interaction force requires the existence of a "referrer", and the gluon is the "referrer" here.

According to the quantum field theory, each particle has its corresponding field, for example, gluon has a "gluon field". A certain amount of energy accumulates on the spot, and it excites gluons.

Ruan Lin also began to look through the data recorded by the particle collider, and should be able to get some inspiration from it.

This imitation lasted for 5 years, the experiment lasted for 12 years, and Ruan Lin had conducted nearly 30,000 experiments, but he still couldn't completely imitate the strong interaction force.

Binding all neutrons and protons is like an insurmountable barrier.

He was complaining in the lab at the moment: "What torture! This is as uncomfortable as the W boson exceeded, and the answer is in front of you, but it can't be touched. ”

Sure enough, a man's wisdom is too weak. Even if I have knowledge of all mankind, it will not help me in some ways. ”

Experiments continued, and Ruan Lin also improved the strong interaction force generation device, which was originally in the shape of a ring, to a 10 cm long and wide square, and they could still be connected together.

"Sure enough, the whole becomes smaller, and the binding ability becomes stronger, and it is almost close to the strength of the strong interaction force."

At this moment, at the femtometer scale, the strength of the strong interaction force generator is 10¹² times that of the gravitational force.

As a result, the atoms' built-in strong interaction force generators are almost the same as wallpaper, directly under the second layer of material, and their generators are 10³⁹ times the strength of gravity, which is indistinguishable from the strength of natural formations.

Over the course of 20 years, Nguyen Lin has been refining the device to perfection to a strength that is now 10¹⁵ times the gravitational pull on the femtometer scale.

Ruan Lin is still making the final revisions, and the importance of this installation to the civilization of the earth is self-evident.

This revision was carried out for another 30 years, and the intensity stayed at 10¹⁷ times the gravitational force at the femtometer scale.

The final product is 6cm in length and width, like a miniature tile.

Ruan Lin couldn't help but sigh: The civilization to which the "atom" belongs should have already solved the theory of grand unification, and their research on microscopic aspects of science and technology is so thorough that even I have to look up to them.

Even though the device has been developed, it has never been possible to achieve it like they put wallpaper, and the final result is simply different from theirs! Because of technical limitations, that's all I can do.

Next, it's time for mass production of the strong interaction force generator! ”
