Start sweeping the universe by rubbing the CPU with your hands.

Development is the last word and the only solution to all crises and difficulties.

No matter how turbulent the galaxy is, no matter how many storms and dangers lie ahead, as long as human civilization itself is strong enough, it can always ensure the continuation of civilization.

At this moment, developing science and technology is the most important task.

But before that, there is one extremely important thing to do.

Han Yang is now over 160 years old. Although Han Yang still looks like a young man thanks to the most advanced genetic technology, he is already deeply aware of the passage of time.

He is no longer young.

"The only meaning of the body to me is to ensure my spiritual existence. Other than that, it has no use."

Han Yang thought calmly: "In this case, since the overall situation of the solar system has been decided, and there is no need for my physical body to appear in person, then, just preserve my physical body."

On Earth, in the capital city, in a secret underground base that is extremely hidden and only Han Yang knows about it in all human civilization, a set of the most advanced hibernation device in all civilizations has been built.

Han Yang got up from Triton and took a special spaceship all the way. Under close escort, he quietly arrived on the earth and entered this hibernation base.

Lying in the hibernation chamber, controlling the robot to activate it, Han Yang's body immediately fell into a long sleep. But his spirit is still active, like spring breeze and rain, permeating every aspect of human civilization without attracting anyone's attention.

Having completely resolved his physical worries, Han Yang devoted himself fully to the follow-up work.

At this stage, after Han Yang's integration, the entire human civilization can be considered stable. Although everything is in ruins, it is already showing great vitality.

The status of scientific researchers, who had not been taken seriously in the past and even had a low status, was once again raised by Han Yang. In terms of education, with the construction of a large number of schools and the implementation of compulsory education policies, a large number of children and teenagers who used to only hang out in the streets and gangs, or who had to work to support their families since childhood, have all gathered in schools. Begin to accept strict management and cultural education.

The fairness and transparency of the system, as well as a large number of urban infrastructure construction needs, as well as the improvement of living needs, etc., have created a stable social order and an economy showing signs of prosperity. Social security has been greatly improved. In less than a year, the legendary rule of not closing the door at night and not picking up lost items on the road has almost been achieved.

This is closely related to Han Yang's holding of the butcher knife in the early days of liberating the solar system.

Why did public security improve to this level so quickly?
  Because most of the most vicious criminals have been killed. Those who were not killed were all locked up and isolated from society. Coupled with strict supervision, the public security of course improved.

After completing the internal integration of human civilization in a very short period of time, Han Yang felt that the time had finally come to devote all his efforts to the development of science and technology.

Of course, Han Yang is still the main force in this stage of development. Those Eta scientists who were captured and came to atone for their sins can be regarded as the main help.

As for human beings' own scientific research power, they cannot exert much power at this stage and can only be regarded as better than nothing.

The reason is also very simple. Hundreds of years of colonial rule have almost completely destroyed the scientific research power of human civilization. The knowledge mastered by existing so-called scientific researchers not only lags behind the times, but is almost all at the applied science level and does not involve basic science.

Although large-scale training and learning has begun, and a complete education system and scientific research talent cultivation system have been established, the results will not be seen in a short time.

But it doesn't matter, Han Yang can wait, and he has enough time to wait.

Under this situation, Han Yang first launched a total of about [-] applied scientific research bases, whose contents are all-encompassing. From textile technology, crop cultivation, genetically modified research, to mechanical equipment, special equipment research, casting technology, chemical technology in the industrial field, to computer architecture optimization in the computing field, materials science research, etc., they are all progressing simultaneously.

After that, with the full help of as many as 50 ETA scientists - at this stage, all ETA people have been treated obediently, and they are doing their best for the tasks issued by Han Yang and letting them teach, they will Give lectures honestly and let them participate in scientific research, and they will carry out scientific research honestly.

Because of the existence of these ETA scientists, Han Yang finally had the qualifications to launch an offensive in basic physics research.

In the past, all the research conducted by Han Yang at the Jade God Base can be classified as applied technology research. In other words, he conducted research within the existing basic physics framework.

Basic physical science determines the upper limit of technology. Without breakthroughs in basic physics, no matter how much research you do, even if you are successful, your achievements will ultimately be limited.

However, basic physics research is the most difficult of all types of scientific research projects. It not only requires a lot of scientific research power and the investment of many outstanding professionals, but also requires a large amount of resource investment.

At the applied physics level, it may even happen that a non-professional talent invents something and obtains a patent because of a flash of inspiration.

However, the research on basic physics can only be led by an entire country or even an entire civilization.

For example, the neutrino telescope currently being built is led by Han Yang.

One of the construction sites selected by Han Yang is a canyon on Vesta in the asteroid belt.

Vesta is about 500 kilometers in diameter. The depth of the canyon above it reaches 100 kilometers. Even because the geology is relatively drillable, Hanyang can drill down another 50 kilometers with relatively low input of industrial resources.

Building a huge neutrino telescope base 150 kilometers underground is something that not even ordinary people, not even a large company, have enough resources to invest in. To accomplish this, we must take the lead from the civilizational level and mobilize forces and resources from the entire civilization.

This is the difficulty of basic physics research.

But no matter how difficult it is, you have to do it.

Without basic physical research, the upper limit of science will always be limited to the current stage. Human civilization will never be able to become strong.

At this moment, with the participation of many ETA scientists, human technical workers, and Han Yang's computing power, the Vesta Neutrino Telescope Base is under intense construction.

At a depth of 150 kilometers underground, a huge internal cavity with a volume of about half a cubic kilometer has been opened up.

In this hollow, Han Yang built a huge water storage tank.

This water storage tank is spherical in shape and has a diameter of 260 meters. In this way, its internal volume is as high as about 920 million cubic meters, and 920 million tons of ultrapure water can be poured into it.

Inside it, an extremely sensitive photoelectric sensor is installed every few meters, which can collect even the smallest internal changes.

Neutrinos are extremely penetrating and require an extremely quiet environment. Based on its characteristics, if you want to study neutrinos, you must go very deep underground.

Because deep underground, the thick rock formations can shield almost all external radiation. Neutrinos, because of their extremely strong penetrating power, can penetrate without any hindrance.

After penetrating the rock formation, the neutrinos will reach this huge water tank.

Although neutrinos are extremely penetrating, they hardly collide with any particles. But there is always a probability in everything. Among a trillion neutrinos, there will always be one or two that accidentally bump into other particles.

The larger the water tank, the greater the probability of collision with neutrinos penetrating itself, and the higher the detection accuracy. This is why the bigger the pitcher, the better.

Once a collision occurs, the movement speed of secondary particles in ultrapure water will exceed the forward speed of photons in the same medium, that is, super-light phenomena will occur.

——This does not violate the theory of relativity. Because only the speed of light in vacuum cannot be exceeded, the speed of light in other media can be exceeded.

Once it exceeds the speed of light, tachyons will release Cherenkov radiation, emitting a faint blue light.

After photoelectric sensors capture this light, the neutrino can be studied to confirm its various properties and fill in the gaps in basic physics theory.

Relative to Han Yang's needs, just one neutrino telescope is obviously not enough.

In fact, on Mercury, Han Yang also built a neutrino telescope base comparable in scale to Vesta.

Mercury is the closest to the sun and has the highest density of solar neutrinos. It is most conducive to studying the internal structure and evolution of the sun through neutrinos, and then studying stellar physics.

Under the thick ice of Europa, Han Yang also built a huge neutrino telescope, specifically used to study the neutrinos released from the interior of Jupiter, and then study the neutrinos of gas giant planets like Jupiter. Physical structure and evolution.

On Triton, Han Yang also built a neutrino telescope.

Although planets like Neptune and Uranus are also gas giant planets, they are slightly different from planets like Jupiter and Saturn. Their more technical name is ice giants.

How ice giants evolve and what their internal structures are like is also a topic worth exploring by Han Yang.

Han Yang has built seven neutrino telescopes alone. Each neutrino telescope requires a huge investment of resources.

In addition to the neutrino telescope, Han Yang also built four array optical telescopes.

The detection performance of an optical telescope depends on its diameter. The larger the diameter, the stronger the detection capability.

However, through some special technology, optical telescopes can obtain unimaginable detection apertures in an almost tricky way.

This is the array telescope.

By placing multiple telescopes in space in all directions of the earth, and combining them, we can obtain a detection effect similar to that of a telescope with an aperture larger than the diameter of the earth.

The farther an optical telescope looks, the more it can explore the evolution of the universe.

Because of the limitation of the speed of light, the light emitted by galaxies or stars that are too far away was actually emitted many years ago. (End of chapter)
