Chapter 242 Neutrino Telescope

Development is the only way to solve all crises and difficulties.

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

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

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

Han Yang is now over 160 years old. Although Han Yang's appearance is still like a young man under the most advanced genetic technology, he has deeply noticed the traces of the passage of time.

He is no longer young.

"The only meaning of the body to me is to ensure the existence of my spirit. Apart from that, there is no use."

Han Yang thought lightly: "In this case, since the overall situation of the solar system has been determined, there is no place where my body needs to appear in person, so keep my body."

On Earth, in the capital city, in a very hidden secret underground base that only Han Yang knows about in the entire human civilization, a set of the most advanced hibernation device in the entire civilization has been built.

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

Lying in the hibernation chamber, operating the robot to start it, Han Yang's body immediately fell into a long sleep. But his spirit was still active, like a spring breeze, and it penetrated into all aspects of human civilization without attracting anyone's attention.

Having completely solved the worries of the flesh, Han Yang devoted all his mind to the follow-up work.

At this stage, after Han Yang's integration, the entire human civilization can be regarded as stable. Although there are many things to be done, it has shown a vigorous vitality.

The status of scientific researchers who were not valued in the past and even low in 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 could only hang out in the streets and alleys, hang out in gangs, or had to work to support their families since childhood, all gathered in schools and began to receive strict management and cultural education.

The fairness and transparency of the system, as well as the large number of urban infrastructure needs and the improvement of living needs, have created a stable social order and an economy that shows signs of prosperity. The social security has been greatly improved. In just less than a year, the legendary "no one locks their doors at night and no one picks up things on the road" has almost been realized.

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

Why did the public security improve to this level so quickly?

Because most of the vicious criminals were killed. Those who were not killed were all locked up and isolated from society. With strict supervision, the public security has certainly improved.

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

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

As for the scientific research power of mankind itself, it cannot play a big role at this stage, and it 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 that the existing so-called scientific researchers have mastered is not only behind the times, but also almost all of it is at the level of applied science, not involving basic science.

Although large-scale training and learning have begun, and a complete education system and scientific research talent training system have been established, it is not possible to see results in a short period of time.

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

Under this circumstance, Han Yang first launched a total of about 13,000 applied science research bases, whose content is all-encompassing. From textile technology, crop planting, transgenic research, to mechanical equipment, special equipment research, casting technology, chemical technology in the industrial field, to computer architecture optimization, material science research in the computing field, etc., they are promoted simultaneously.

After that, with the full help of up to 500,000 Itar scientists - at this stage, all Itar people have been subdued and devoted to the tasks issued by Han Yang. If they are asked to teach, they will teach honestly, and if they are asked to participate in scientific research, they will carry out scientific research honestly.

Because of the existence of these Itar scientists, Han Yang finally has the qualifications to launch an offensive against basic physics research.

In the past, when Han Yang was at the Yushenxing base, all the research he conducted could be classified as applied technology research. That is, he conducted research within the existing basic physics framework.

Basic physics science determines the upper limit of science and technology. Without a breakthrough in basic physics, no matter how much research is done, even if it is done in a fancy way, the achievements will be limited.

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

At the level of applied physics, it is even possible that a non-professional talent will invent something and obtain a patent because of a flash of inspiration.

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

For example, the neutrino telescope that Han Yang is leading the construction of at this moment.

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

Vesta has a diameter of about 500 kilometers. The depth of this canyon on it reaches 100 kilometers. Even because of the relatively easy geological drilling, Han Yang can drill down another 50 kilometers with lower industrial resources.

To build a huge neutrino telescope base 150 kilometers underground, this kind of thing, not to mention ordinary people, even a large company does not have enough resources to invest.

It must be led from the civilization level, and forces and resources from the entire civilization must be mobilized to invest in it to complete it.

This is the difficulty of basic physics research.

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

Without basic physics research, the upper limit of science will always be limited to this stage. Human civilization will never be strong.

At this moment, with the participation of many Ita scientists, human technical workers, and Han Yang's computing power, the Vesta neutrino telescope base is under intensive 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 tank.

This water tank is spherical, with a diameter of 260 meters. In this way, its internal volume is as high as 9.2 million cubic meters, which can be filled with 9.2 million tons of ultra-pure water.

Inside it, a photoelectric sensor with extremely high sensitivity is installed every few meters, which can collect even the slightest internal changes.

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

Because in the deep underground, the thick rock layer can shield almost all external radiation. However, neutrinos can penetrate unimpeded because of their strong penetrating power.

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

Although neutrinos have extremely strong penetrating power and almost never collide with any particles. But there is always a probability for everything. Among a trillion neutrinos, there will always be one or two that accidentally hit the rest of the particles.

The larger the water tank, the greater the probability of collision with the neutrinos that penetrate it, and the higher the detection accuracy. This is why the larger the water tank, the better.

Once a collision occurs, the speed of the secondary particles in ultrapure water will exceed the speed of photons in the same medium, that is, superluminal phenomena will occur.

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

Once the speed of light is exceeded, superluminal particles will release Cherenkov radiation and emit a faint blue light.

After the photoelectric sensor captures this light, it can study neutrinos to confirm its various characteristics and fill in the gaps in basic physics theory.

Compared with Han Yang's needs, just one neutrino telescope is obviously not enough.

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

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

Under the thick ice layer of Europa, Han Yang also built a huge neutrino telescope, which is specially used to study the neutrinos released from the interior of Jupiter, and then study the physical structure and evolution of gas giants like Jupiter.

On Triton, Han Yang also built a neutrino telescope.

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

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

Han Yang 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 aperture. The larger the aperture, the stronger the detection capability.

However, through some special technology, optical telescopes can almost get unimaginable detection apertures by trickery.

This is an array telescope.

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

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

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