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

For example, from a star that is 10 light-years away, the light seen on the earth now is what it emitted 10 years ago.

By analogy, the light we see now in an extragalactic galaxy more than 100 billion light-years away—a galaxy for short—was emitted 100 billion years ago.

And the lifespan of the universe up to this moment is only over [-] billion years.

In this way, the river system 100 billion light-years away, what is displayed in the telescope at this moment is the image of the early formation of the river system.

In this way, Han Yang will be able to clearly see what the early universe looked like.

The life and evolution process of the entire universe was presented to Han Yang in this way, allowing Han Yang to know how the river system evolved, how gravity shaped the current shape of the river system, and how dark matter and dark energy are here. What role does it play, etc.

In addition to optical telescopes, Han Yang also built a large number of radio telescopes, infrared telescopes, X-ray telescopes, and so on.

In addition, a more important piece of observation equipment is the gravitational wave telescope.

The penetrating power of gravitational waves is more than a quadrillion times greater than that of neutrinos. For example, even if the universe at this moment is completely filled with thick steel, the attenuation of gravitational waves from one end of the universe to the other will still be very small, almost nonexistent.

Based on the super penetrability of gravitational waves, gravitational wave detection can detect many targets that cannot be detected by other detection methods.

For example, a river system covered by thick nebulae, or an object covered by numerous stars and numerous chaotic radiations.

At this stage, the gravitational wave detector built by Han Yang plays an important role in the detection of many extreme cosmic physical processes such as the merger of black holes, the merger of neutron stars, the merger of neutron stars and black holes, the merger of stars, and even the merger of river systems.

The universe is a natural laboratory. Many of these scenarios cannot be simulated at all by simulation. Only by directly detecting these processes can we understand what exactly happened during this process, what unknown mechanisms and forces are at work, and can we reveal the underlying mysteries of the universe in a deeper way.

Just like the merger of stars.

There are many stars in the universe with masses that are beyond imagination. According to the principles of stellar evolution, they simply cannot be that big.

Through further research, Han Yang confirmed that many of the high-quality stars were actually formed by the merger of multiple stars.

Violent collisions, mutual gravitational pull, different element structures and layered structures, after being unified and scattered, formed this unimaginable star.

But for this kind of collision, other detection methods are usually not useful. Because they are too far away.

However, the process of violent collision of high-quality stars such as stars will release strong gravitational waves. By studying such gravitational waves, we can reveal the mysteries they contain.

In addition to many telescopes, Han Yang has also built a large number of different types of particle accelerators. The largest one, Han Yang, is built directly in space far away from the ecliptic plane, with a length of tens of thousands of kilometers and can almost circle the earth.

It is a straight line equipped with millions of particle electromagnetic accelerators.

Under the acceleration of these devices, the particle beams starting from both ends will be accelerated to a speed very close to the speed of light, and then violently collide.

At the moment of collision, all the messy subatomic particles such as gluons, hadrons, taons, muons, and even quarks inside will break away from their original restraints and be knocked out.

(This is not rigorous, but due to space limitations, I cannot go into details. Readers can probably understand what is going on)
  It was like two big watermelons colliding together, and all the pulp and seeds inside burst out.

Obviously, the faster the impact, the higher the energy, and the harder the "collision", the more internal subatomic particles will be knocked out, which is more conducive to subsequent research.

The speed of the particle beam depends on the number and power of the accelerating device, which in turn depends on the length of the accelerator. That's why Han Yang wanted to make this accelerator so big.

In this way, Han Yang can study the smallest physical structures, find more fundamental particles that have not been discovered before, study their evolution, study their interactions, and so on.

In order to power this giant particle collider, Han Yang built more than 100 large-scale nuclear fusion power stations next to it. Coupled with maintenance equipment, research equipment, material supply and transfer equipment, as well as a large number of warships stationed to ensure safety, etc., a huge base is directly formed in space with it as the core.

On average, more than 100 heavy-lift cargo spacecraft travel between the super particle accelerator base and various planets every month to support its operation.

A base of this size requires such high investment, and the input may not necessarily result in output. Even if there is output, it is impossible to determine what the output will be. It is also impossible to predict how much the scientific research results will play. It is impossible for any commercial company to invest in planting something.

Even if you want to, you can't afford it.

But Han Yang jumped in without hesitation. And, once created, there are three.

This is still the largest. On various planets, Han Yang has also built more than 100 smaller particle collider bases, specifically used for particle physics research in subdivided fields.

In addition to these equipment, Han Yang has also built numerous high-power electromagnetic wave generators, strong magnetic field laboratories, ultra-low temperature laboratories, ultra-high temperature laboratories, over-pressure laboratories, etc.

At extremely low temperatures, even extremely close to absolute zero, matter will exhibit very peculiar physical properties.

Superconductivity is a typical low-temperature phenomenon.    The closer we get to absolute zero, the more things can be studied and explored.

The same goes for ultra-high temperatures. At temperatures as high as one billion degrees or tens of billions of degrees, the properties of matter will also be very strange.

The overpressure laboratory applies extreme pressure to objects to study changes in their properties.

The core of the sun is the most stressful place in the solar system. The pressure there is about 2600 billion times that of the Earth's atmosphere. There, the properties of matter are equally wonderful.

The core of Jupiter is the second most stressful place in the solar system after the core of the sun. It is speculated that the hydrogen in the core of Jupiter may even be compressed to the point where it has metallic properties, which is the so-called metallic hydrogen.

Studying the property changes of substances under ultra-high pressure is not only of great benefit to basic physics, but also to materials science, engineering, etc.

But correspondingly, it is not easy to study these things.

They also require extremely large equipment, even bases, to conduct research, and consume extremely high energy.

It is not a lie that a scientific research base consumes more energy than an entire city. It can even be regarded as a slight underestimation of the power consumption capacity of these scientific research bases.

For this reason, Han Yang had to build many more nuclear fusion power stations to power them.

In addition to these studies involving basic physics, what Han Yang attaches most importance to is research in computational science.

Research in computing science is currently divided into two aspects. One is the continued in-depth study of quantum computers, and the other is the optimization and transformation of electronic computers.

To this end, Han Yang has also built many computing research bases and invested a lot of resources.

There is a general term for all types of large-scale scientific research facilities and bases, called big scientific installations, which is specifically used to refer to these scientific research installations that are extremely expensive and energy-consuming and can only be built by the country or civilization.

At this stage, it has only been ten years since the solar system was liberated, and the number of large scientific installations built by Han Yang has exceeded 1000, and it is still increasing rapidly.

You know, before the arrival of the Eta people, at the peak of human civilization, the number of large scientific devices was only about 200. At this moment, Han Yang almost single-handedly increased this number by more than five times.

Obviously, the number and operating efficiency of large scientific devices are the most important indicators for measuring the speed and potential of a civilization's technological development. At this moment, at least in the second-level civilization stage, Han Yang asked himself that he had achieved almost the ultimate level.

During this period, as many as 50 ETA scientists were teaching human scientists through the Zhixue Network - and at the same time teaching Han Yang, while they were leading the construction of various large scientific equipment, and at the same time, Han Yang's life is extremely busy with research work on various scientific research tasks issued by him.

But no matter how busy they are, no one from Eta dares to complain or slack off.

The scene of Han Yang's brutal massacre of tens of thousands of Eta people is still vivid in his mind. At this time, you are cheating and cheating, don’t you want to live anymore?
  Time moves forward rapidly, and in the blink of an eye, more than twenty years have passed since the liberation of the solar system.

During these two decades, the entire human civilization has flourished under Han Yang's secret leadership.

With the advancement of science and technology and the prosperity of the economy, people have regained the dignity and hope they had lost in the past and live and work in peace and contentment.

Infrastructure construction covering the entire solar system is in full swing. Although it has not been completed yet, it has completely changed the appearance of the past.

New cities are rising one after another. Transportation within cities, transportation between cities, transportation between planets, etc. are convenient and fast.

A huge amount of materials and people flow between different planets and cities, injecting sufficient vitality into each city.

The tourism industry is booming. After busy work, even ordinary people can afford a long-distance interstellar trip to the edge of the solar system, adding a touch of brightness to daily life.

The cost of medical care has been greatly reduced, and medical care has become almost free, so that people no longer have to go bankrupt due to illness. The great improvement of medical technology has led to a rapid increase in people's average life expectancy, which has more than doubled from only 180 years old to 380 years old now.

But this is not what Han Yang values ​​most.

What Han Yang values ​​most is that after more than two decades of continuous heavy investment, human scientific research capabilities have finally been cultivated.

After Han Yang opened the new era doctoral examination, a total of 220 million candidates with complete education in human civilization with a total population of about 430 billion signed up to take the examination. In the end, about 90 people passed and received the title of doctorate. .

Next year, this number is expected to increase. In only about ten years, Han Yang was able to cultivate a scientific research system with a total number of tens of millions.

After having a sufficient number of scientific researchers, Han Yang's early research on basic physical theory and applied physics immediately blossomed into brilliant flowers.

One major scientific research project after another has achieved breakthroughs, and one major achievement after another has been presented to Han Yang and to all mankind.

At this moment, Han Yang could finally sigh with satisfaction: "The development of civilization is finally on the right track." (End of Chapter)
