If you can't beat it, you can run, it's not a shame.

Chen Yue guessed that this mode of existence of his own should be relatively rare in the universe. Gregarious intelligent civilizations like human civilization should be more common.

At the same time, as long as there is enough computing power, its development potential is much higher than that of ordinary social intelligent civilization.

As long as you can escape, you can find a remote galaxy that no one pays attention to for a while, and you can fully recover your strength and even go further. When the time comes, I'll come back and get the field back.

Therefore, Chen Yue did not have a little psychological burden for escaping.

The only thing to worry about is that you can't even escape.

Without controlled nuclear fusion technology, you can't even leave the solar system, so what do you say to escape?

"However, controlled fusion technology is too difficult. In a short period of time, it was simply impossible for me to master. Maybe...... Can I develop some weapons technology first? If aliens do invade the solar system, I can at least fight them. ”

Chen Yue thought silently. After a few moments, he dismissed the thought himself.

"It doesn't make sense at all."

At this stage, the weapons that can be developed by oneself are some ordinary chemical bomb weapons and the like, and there is an electromagnetic cannon in the sky, and then there is no original Z bomb - even hydrogen bombs cannot be built.

This primitive weapon is for a super alien civilization with the ability to travel interstellar and reach the solar system from the rest of the galaxy...... Does it really make sense?

Not only is it useless, but the development of these weapons will also occupy a huge share of their computing power and slow down their own development.

"Forget it, no matter what weapons are useless at this stage. If there is an alien invasion, I would kill myself. Or don't make a fuss.

The most important task at this stage is still to do my best to develop science and technology, and when I have mastered the technology of controlled nuclear fusion, then I will develop weapons systems! ”

Chen Yue made up his mind.

The appearance of this incident made Chen Yue yearn for the progress of science and technology like never before. It also made him even more afraid to slack off—although he hadn't slacked off before.

At this moment, he is no longer satisfied with Europa. His footsteps have begun to extend to the other three Galileo satellites, and he has conducted a detailed survey of the three large moons to prepare for future development plans.

Europa, although it belongs to the big satellite, is still too small after all. Judging from Chen Yue's current development rate, it will soon not be able to supply enough resources.

During this period of time, in terms of scientific and technological development, Chen Yue's chip process is still stuck at five nanometers and has not made any progress.

Although he was anxious, after all, more advanced chip technology means higher computing power and faster development speed, but he also knows that he can't be in a hurry in this regard, and he has to accumulate slowly.

In terms of energy, after steadily mastering nuclear fission reactor technology, Chen Yue began to attack the next level of nuclear fusion.

Of course, it is only in the pre-research stage. Chen Yue knew in his heart that it was unlikely to break through in a short period of time.

However, if you want to develop the rest of the large satellites, the transportation between different planets, relying solely on chemical energy rockets or spaceships, is somewhat unable to meet the current needs.

We have to develop more efficient energy sources and develop new types of spacecraft.

"Nuclear fusion will not work in the short term, in order to meet the subsequent needs, then we can only consider the miniaturization of nuclear fission reactors and build nuclear fission spacecraft."

Chen Yue thought so.

Fission reactor miniaturization technology already exists on Earth. For example, nuclear submarines, nuclear-powered aircraft carriers, etc., are practical applications of miniaturization technology.

However, Chen Yue's miniaturization is not aimed at submarines or aircraft carriers, but spaceships.

Chen Yue wants to build a nuclear-powered spacecraft!

Spaceships are a leap from chemical energy to nuclear energy. Once successful, Chen Yue's spaceship, both in terms of performance and endurance, will be greatly improved, and there is even hope that it will build a real space warship, with the ability to fight in space, and truly have a certain degree of self-protection ability.

Of course, it is debatable how much capability a spacecraft that uses nuclear fission as a power source in space operations and how much protection it can provide.

Either way, its value cannot be overlooked.

But nuclear-powered spacecraft are not so easy to build.

Ships move through space, relying on two things. One is energy, and the other is working fluid.

Like a chemical rocket, it is directly a two-in-one energy and working fluid.

For example, metamethylhydrazine, after this thing is combined with an oxidant, it directly heats the generated gas to a very high temperature and has a very high pressure, and then directly sprays it out to obtain a reverse thrust, which can propel the rocket ship forward.

Among them, metamethylhydrazine and oxidant are energy sources, and the gas generated by combustion that is ejected out is the working fluid.

In the case of nuclear-powered spaceships, there are fission reactors to supply energy, but where does the working fluid come from?

If there is nothing to eject, how can the reverse thrust come from?

Do you have to prepare a large pile of gas or something else for the fission reactor to heat and pressurize and then eject out to get the thrust back?

But in this way, there is no point in building a fission reactor. Because it's as bulky as the chemical thrust, it's not space-saving and mass-saving at all.

If you want to build a nuclear-powered spacecraft, the first thing you need to solve is the problem of working fluid.

"It seems that the only way to develop ion propulsion technology is to develop."

Chen Yue thought secretly.

Ion propulsion technology, as the name suggests, its working fluid is ionic.

There are two sources of reverse thrust, one is the amount of working fluid, and the other is the speed of working fluid.

With the same injection speed, it is obvious that the more working fluid is sprayed, the greater the reverse thrust will be obtained.

For the same mass of working fluid, it is also obvious that the faster the speed of the jet, the greater the reverse thrust obtained.

When the quality of the working fluid cannot be improved, the only way to increase the speed of the jetting working fluid is to find a way.

Ion propulsion technology is one such technology.

Its essence can probably be regarded as a particle accelerator - similar to the particle collider that Chen Yue uses for scientific research.

The gas is ionized and then accelerated by an electromagnetic field, so that it is ejected from the rear at a very high speed to obtain reverse thrust.

Because ions can be accelerated to high speeds very close to the speed of light, compared to the working fluid jets of chemical rockets, which typically range from a few kilometers to more than a dozen kilometers per second, there is a huge efficiency gap between the two.

It is only with ion propulsion that nuclear-powered spacecraft become truly valuable.

However, even at the peak of human beings, ion propulsion technology was still in its infancy.

The reverse thrust of the most advanced ion engine is just enough to push the weight of a piece of paper......
