"Everyone here knows that an atom is a microscopic particle, but in fact, most of the space occupied by an atom is empty. Even in dense metals, the distance between one nucleus and another is as far away as the Earth to Mars......"

Fang Yuan went on to explain the structure of the strongly interacting materials, not for the scientists on the scene, of course, but for the old hooligans who played with power and politics on the other end of the video conference.

"The nucleus is made up of protons and neutrons, and the strong interaction force is the force that combines protons and neutrons into a nucleus. A strong interaction force material is to lock and connect the protons and neutrons of a substance together.

In other words, the distance between the nuclei in the strongly interacting material is gone, resulting in a truly dense structure with an absolutely smooth surface.

"As for the hardness of materials with strong interaction forces, I won't explain it, anyway, it's trivial to resist nuclear bombs."

After the explanation, the physicist from the Hairy Bear Country also finished operating the scanning tunneling microscope and imaging again.

As before, the surface of the strongly interacting material is absolutely smooth, and the protons and neutrons are locked together by the strong interacting force, forming an indestructible layer of mirrors.

Unless the nucleus structure can be broken, this layer of material cannot be destroyed.

The other end of the video conferencing network.

The chief of the White Eagle Congress knows stocks, knows shorts, knows hedging, knows about washing, and is a good hand at playing finance anyway.

However, if you ask him what a strong interaction force material is, it is absolutely unknown.

Of course, he knows what a nuclear bomb is.

So he turned back to the secretary and asked, "Is what he said true?" Is that thing really nuclear bomb-resistant? ”

"Yes, according to information received by the intelligence services, this material is difficult to destroy even with a nuclear bomb." The congressional secretary replied.

This time, the chief of the White Eagle Congress was finally a little surprised, and suddenly realized that it was not so safe to hold thousands of nuclear bombs in his hands.

"Which scientist made this material? Bought him over. The Chief of the White Eagle Congress immediately expressed a strong enthusiasm for this material.

Can you not be enthusiastic?

Wearing such a suit of armor and being able to resist nuclear bombs, this is much safer than a bulletproof Rolls-Royce.

"Mr. President, I'm afraid this will be difficult." The congressional secretary expressed helplessness.

"What's so difficult? If there is difficulty, it means that the money is not enough, and it is no problem to give 100 million dollars for this technology. "The Chief of the White Eagle Congress insisted on buying the technology.

"Sir, this is impossible, and this technology is still in the research stage, and the research budget given by the Davis Group is more than the military expenditure for a hundred years." The congressional secretary explained helplessly.

"What? This kind of thing costs so much money? Are these Chinese people crazy? The chief of the White Eagle Congress said with an exaggerated expression.

After he finished speaking, he looked at the head of the White Eagle Aerospace Agency and said, "Brewer, what do you think about this matter?" ”

Brewer, who is the head of NASA at the White Eagle Aerospace Agency, was speechless about the chief of Congress, and replied: "The matter of scientific and technological research can be discussed within NASA, and Mr. President does not need to be tired." ”

This sentence translates to a more straightforward meaning: You don't understand anything, so you better shut up.

……

The venue of the Symposium on Planetary Defense in the East China Sea.

After Fang Yuan was responsible for displaying the strong interaction force material, he stepped off the stage and sat back next to Yang Yuping.

Several of the big bulls in the Chinese scientific circles around them gave a thumbs up and expressed their appreciation.

"That's a good point."

Yang Yuping also expressed his approval, of course, referring to the humor in the explanation, as for the scientific and technological content explained, in the eyes of these scientific giants, it is just basic knowledge.

After the presentation of the material.

The spokesman of the East China Sea continued to go up and preside over the bidding of scientific research projects: "You have all seen that strong interaction materials are the strongest shield of future civilization technology, and this technology has been launched in front of our eyes.

"Huaxia sincerely invites the world's top scientific teams to come to cooperate in research, and all scientific research successes will be jointly held by all participating countries and share the benefits of scientific research."

The modalities for the scientific research IPO have been announced.

Of course, it is impossible to decide on such a major matter on the spot.

Even if many scientists have already made a move, they still need to go back and discuss it before they can decide.

Next.

Donghai spokespeople also announced several other scientific research offers, namely antimatter technology, Dyson sphere, and gravitational wave technology.

In addition to antimatter technology and strong interaction materials, among the pinnacle technologies of stellar civilizations, there is also an iconic technology called the Dyson sphere.

The reason why stellar civilizations are called stellar civilizations is because civilizations of this level can make full use of the resources of the star system.

Where does the largest amount of energy come from in a galaxy?

Stars, of course.

Taking the solar system as an example, the sun is not only the main source of energy in the entire solar system, but also accounts for 99.84% of the total mass of the entire solar system.

Energy, on the other hand, is an important indicator of the level of civilization.

At this stage, human beings still rely on oil as their main energy source.

Although there is a star source mine, this star source is so expensive that it cannot be used for daily use.

If a civilization wants to develop to a high level, it must also reach a corresponding height in energy extraction.

In a galaxy, stars are the main source of energy.

Therefore, for a civilization to develop into a stellar civilization, it must eventually exploit stellar energy.

In the solar system, only about 1/2.2 billion of the energy released by solar nuclear fusion reaches Earth.

In other words, if the sun's energy can be fully extracted, it can support the solar energy needed by 2.2 billion Earths, which is a terrible statistic.

Therefore, the Dyson sphere is an important symbol of a stellar civilization, representing the development of a civilization to a height where it can exploit stellar energy.

A spokesman for the East China Sea also announced the scientific research plan of the Dyson sphere, which once again caused a sensation in the scientific community.

With the current level of science and technology of the earth, the earth's resources have not yet been fully exploited, and now we start to think about extracting the energy of the sun, and it seems that I want to run before I have learned to walk.

However, which of the scientific research projects proposed at this symposium on planetary defense did not surpass the current level of science and technology of human civilization?

Now if human civilization wants to resolve the impending apocalyptic crisis, it must start learning to run before it learns to walk.

Because there is no time to study slowly.

The only thing that is fortunate is that now there is a real possibility for humans to skip grades.

Fang Yuan was slightly surprised when he heard the Dyson ball plan, turned his head to look at Yang Yuping, and asked, "Do you really want to engage in Dyson ball?" ”

Yang Yuping just smiled and didn't answer.
