The discussion ended in silence, and everyone walked out with a heavy face. Even the optimists were no exception, and Dr. Rimbaud hurried back to the Tesla Research Institute with a worried look on his face.

Anyway, as long as this kind of discussion about the universe is concerned, one conclusion is bound to be correct: that is, the universe is too great and human beings are too small.

It was the first time for Yu Yifeng to participate in this kind of discussion, and he was extremely stimulated, and his heart was also extremely unhappy. If he is unhappy, he can't vent his frustration on others, he just keeps frowning.

He's thinking about civilized warfare. Preparing for a rainy day is a quality that a leader must have, and if you wait until war comes, it will be too late.

What weapons does humanity have now? Except that a nuclear bomb can symbolically protect oneself, it is almost the same as fighting with bare hands.

Old weapons like machine guns, mortars, missiles, etc., are good against their own people, but they are a scum in space warfare.

Laser weapons and electromagnetic pulse weapons can be considered for research and development, although with the existing technology of mankind, there will not be much power at all, but it is also the future research direction.

The United States and Russia have both studied laser weapons, which are so powerful that they can barely destroy a space satellite. But this kind of power is too small on a cosmic scale, and Yu Yifeng doesn't think that in just a few years, there will be any qualitative changes in this weapon......

As for the EMP weapon, there is no particularly good progress for the time being, it requires too much energy.

So, the most important thing is still a nuclear bomb! Although it flies slowly, is easy to intercept, and has flaws of one kind or another, it is still the most powerful means of attack for humans.

Nuclear bombs, especially hydrogen bombs, are weapons that can theoretically increase their power indefinitely.

However, due to technical and political reasons, peace has become an eternal theme of development, and mankind's nuclear bomb technology has almost come to a standstill in the 21st century. Until now, the strongest nuclear bomb that mankind can build is a billion-ton yield helium-3 nuclear bomb!

For human beings, the raw material of the helium-3 nuclear bomb "helium-3" is still a scarce resource, and mankind has obtained one or two thousand tons of helium-3 from the moon, which is completely sufficient at present, but it is not very sufficient in the long run.

If you use it, you can't replenish it!

A nuclear bomb with a gigatron yield, it sounds exaggerated, but it's really nothing in an interstellar war. Yu Yi Feng knew this.

How much yield does a nuclear bomb that can smash the earth need?

In the past, mankind kept saying that a nuclear war could destroy the earth ten times. This statement is simply laughable, all the 37,000 nuclear warheads on the earth are equivalent to tens of billions of tons of TNT, and they can't hurt a single hair of the earth at all.

The original Chicxulub meteorite impact led to the extinction of the dinosaurs, releasing energy equivalent to 120 trillion tons of TNT equivalent, but for the earth, it also added a scar.

120 trillion tons! 10,000 times the amount of all nuclear weapons, there is one more scar, you can imagine how huge the earth is, how difficult it is to blow it up.

However, the 37,000 nuclear bombs of mankind can completely destroy the global ecological environment and make human beings extinct ten times, which is basically no problem.

But what is the relationship between the destruction of humanity and the destruction of the planet? Can humans represent the planet?

Therefore, Yu Yifeng clearly knew how terrifying an alien weapon that could directly blow the earth apart was......

Well, he didn't want to go that far, but he did desperately want to research more powerful and violent weapons. He already had an idea in his mind: a nuclear bomb that would use ordinary hydrogen for fusion.

Hydrogen, the most common and most common element in the universe, accounts for more than 90% of the total elements in the universe, if you can use these ordinary hydrogen elements to make nuclear bombs, then its yield and production can be greatly improved, and you don't have to worry about raw materials anymore!

Such a nuclear bomb, called a four-hydrogen nuclear bomb, is also the most powerful and ultimate nuclear bomb!

Conventional nuclear bombs require the use of rare elements such as deuterium and tritium, which are very difficult to obtain, require industrial production, and the energy consumption is very large, and the output cannot be increased at all.

Moreover, tritium is a radioactive element, and its half-life is only 12.43 years, which is too short. In other words, such a nuclear bomb is completely impossible to store for a long time.

The helium-3 nuclear bomb invented by Professor Ding Yidong is more advanced and violent, and helium-3 is extracted from the moon, which is almost ready-made, and the industrial consumption is relatively small for people.

But the amount of helium-3 is still too small, and when it is used up, it is gone, and humans cannot replenish it.

Therefore, Yu Yifeng is considering simply researching a stronger and more versatile four-hydrogen nuclear bomb!

Inside the core of the sun, the fusion of four hydrogen nuclei into one helium nucleus is continuously carried out, and a large amount of energy is released at the same time. This reaction, called tetrahydrofusion, is also the sun's main source of energy.

The principle of the four-hydrogen nuclear bomb is similar to the reaction process inside the sun's core, which is to fuse four hydrogen atoms into one helium nucleus, and at the same time release a large amount of energy. The process does not require any deuterium, tritium, or helium-3, but only ordinary hydrogen.

Therefore, the four-hydrogen nuclear bomb completely solves the problem of raw materials, and the output and yield can be expanded indefinitely, which can be said to be the strongest and ultimate nuclear bomb!

But why don't people study the four-hydrogen bomb, but the deuterium and tritium hydrogen bombs?

Because it's really too hard, it's too hard, think about it, ordinary nuclear fusion, is made up of a nuclear reaction between two atomic nuclei. However, a four-hydrogen nuclear bomb requires 4 hydrogen nuclei to collide together at the same time! How can this be twice as difficult? A hundredfold more!

This kind of super weapon, of course, can't be ordered by Yi Feng with a pat on the head, and it still needs to be discussed by everyone......

As soon as they heard the news, several people from the Ministry of Security were gearing up and excitedly dying, and mankind finally had an imaginary enemy, and there would also be new models of weapons and equipment. What kind of laser weapons, electromagnetic kinetic energy cannons, think about it is advanced, powerful! Zhao Yao's black face kept trembling and roared excitedly, but Xu Yunjin slapped it with a big mouth. "Be quiet!"

Xu Yunjin was actually excited to death in his heart, but he didn't show it. After being an official for this period of time, he also knew that he was a bit of a city government, and he couldn't put his joy and anger on his face like Zhao Yao.

"I'll enter later, don't embarrass me!"

"Yes!"

……

It was a small meeting, attended only by the head Yu Yifeng, a few people from the Ministry of Security, and the heads of several large research institutes. Everyone discussed the feasibility of four-hydrogen nuclear bombs, laser weapons, and electromagnetic weapons.

Professor Ding Yidong looked at Yu Yifeng's request half fanatically and half worriedly: "Four-hydrogen nuclear bomb...... It's a bit difficult. ”

"At the core of the sun, the temperature is up to 15 million degrees, and the pressure is equivalent to 300 billion atmospheres. The temperature is fine, but we humans can't do this kind of intense pressure......"

300 billion atmospheres is really too exaggerated, and the maximum pressure before the explosion of the hydrogen bomb is at the level of 1 million atmospheres...... "Perhaps, we can reduce the pressure demand by increasing the temperature." Ding Yidong frowned and thought.

"Yes......"

Dr. Felix nodded, "As the temperature rises, the pressure required for a nuclear reaction will definitely decrease. But we don't have such a functional model yet, and even if we use a helium-3 nuclear bomb with the highest reaction temperature, we don't know if it's feasible......"

Seeing that many scientists were silent together, and even Ding Yidong, who had always been keen on weapon research, did not speak, Yu Yifeng felt that he still thought about it too simply, this kind of ultimate nuclear bomb is not so easy.

If it were easy, the human government would have been studying it on Earth a long time ago, so why wait until now?

He immediately said: "In this way, there is no need to rush the research of the four-hydrogen nuclear bomb for the time being, I will just mention it here, and start first." Let's go back and think about what a good plan is, and there is no special time limit. ”

Everyone nodded together, they still have to study automated production during this time, the wolf is working on super trains, Tesla is researching excavators, and the task is really heavy. Maybe I'll think about this kind of problem when I'm free in the future.

"By the way, the laser weapons and electromagnetic weapons you mentioned should not be too problematic...... Ding Yidong said suddenly: "It has been studied by various countries in the past, and it is quite limited in the atmosphere, and the lethality is really touching, and destroying a car is so-so." If it is used in the space battlefield......"

Ding Yidong smiled and didn't say any more, what he meant was that Yu Yifeng shouldn't expect too much in the end.

"No way, this high-speed weapon must be a tendency in space warfare. We can only start small and grow. Yu Yifeng shook his head and said, "If you don't study, there will be no development...... Please, everybody. ”
