Chapter 243 Large Scientific Facility

For example, for a star 10 light years away, the light we see on Earth right now was emitted 10 years ago.

By analogy, for a galaxy more than 10 billion light years away, the light we see right now was emitted 10 billion years ago.

The life span of the universe is only over 10 billion years.

In this way, the image of the Milky Way 10 billion light years away, displayed in the telescope at this moment, is the image of the Milky Way in its early formation.

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

The life course and evolution process of the entire universe are presented to Han Yang in this way, allowing Han Yang to know how the Milky Way evolved, how gravity shaped the current Milky Way, what role dark matter and dark energy played in it, and so on.

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

In addition, a more important observation device is the gravitational wave telescope.

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

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

For example, the Milky Way covered by thick nebulae, such as targets covered by many stars and many chaotic radiation.

At present, the gravitational wave detector built by Han Yang plays an important role in the detection of many extreme cosmic physical processes such as black hole mergers, neutron star mergers, neutron star and black hole mergers, star mergers, and even Milky Way mergers.

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

For example, star mergers.

There are many stars in the universe with a mass that is beyond imagination. According to the principle of stellar evolution, they simply cannot be so large.

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

Violent collisions, mutual gravitational pulls, different element structures and layered structures, after being uniformly dispersed, form this unimaginable star.

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

However, the violent collision process of high-mass stars will release strong gravitational waves. By studying this gravitational wave, the mysteries contained in them can be revealed.

In addition to many telescopes, Han Yang also built a large number of different types of particle accelerators. The largest one, Han Yang built directly in space far away from the ecliptic plane, is tens of thousands of kilometers long 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 extremely close to the speed of light, and then violently collide.

At the moment of collision, all the gluons, hadrons, tau, muons, and even quarks and other messy subatomic particles inside will break free from their original constraints and be knocked out.

(This is not rigorous, but due to space limitations, I cannot elaborate on it. You readers can just understand what is going on)

It's like two big watermelons collide with each other, and the pulp and seeds inside will all burst out.

Obviously, the faster the collision speed, the higher the energy, and the harder the "collision", the more subatomic particles inside will be knocked out, and the more conducive to subsequent research.

The speed of the particle beam depends on the number and power of the accelerator, and then on the length of the accelerator. That's why Han Yang wants to make this accelerator so big.

In this way, Han Yang can study the most subtle physical structures, find more basic particles that have never 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 nuclear fusion power stations next to it. In addition to the maintenance equipment, research equipment, material supply and transfer equipment, and a large number of warships stationed to ensure safety, etc., a huge base was directly formed in space with it as the core.

On average, more than 100 heavy cargo ships travel back and forth between the super particle accelerator base and the planets every month to support its operation.

A base of this scale, such a high investment, and the investment may not necessarily have output. Even if there is output, it is uncertain what the output will be, and it is impossible to estimate how much effect the scientific research results produced can have. It is impossible for any commercial company to invest in such a thing.

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

But Han Yang invested without hesitation. And he built three at a time.

This is still the largest one. On each planet, Han Yang also built more than 100 smaller particle collider bases, which are specially used for particle physics research in subdivided fields.

In addition to these devices, Han Yang also built many high-power electromagnetic wave generators, strong magnetic field laboratories, ultra-low temperature laboratories, ultra-high temperature laboratories, superpressure laboratories, etc.

At extremely low temperatures, even extremely close to absolute zero, materials will show very strange physical properties.

Superconductivity is a typical low-temperature phenomenon.

The closer to absolute zero, the more things can be studied and explored.

The same is true for ultra-high temperatures. At temperatures as high as one billion degrees and tens of billions of degrees, the properties of materials will also be very strange.

The superpressure laboratory is to apply great pressure to objects to study their changes in properties.

The core of the sun is the most pressured place in the solar system. The pressure there is as high as about 260 billion times the atmospheric pressure of the earth's atmosphere. There, the properties of matter are also wonderful.

The core of Jupiter is the second most pressured place in the solar system after the core of the sun. It is speculated that the hydrogen at the core of Jupiter will even be compressed to have the properties of metals, which is the so-called metallic hydrogen.

Studying the changes in the properties of matter 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, or even bases to conduct research, and the energy consumption is extremely high.

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

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

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

The research on computational science is currently divided into two aspects: one is the continued in-depth research on quantum computers, and the other is the optimization and transformation of electronic computers.

For this reason, Han Yang also built many computational science research bases and invested a lot of resources.

All types of large-scale scientific research facilities and bases have a general name, called large scientific facilities, which are specifically used to refer to these scientific research facilities that are extremely expensive and consume a lot of energy and can only be built by countries or civilizations.

At this stage, it has only been ten years since the liberation of the solar system, and the number of large scientific facilities built by Han Yang has exceeded 1,000, and is still increasing rapidly.

You know, before the arrival of the Itars, at the peak of human civilization, the number of large scientific facilities was only about 200. At this moment, Han Yang has increased this number by more than five times almost by himself.

Obviously, the number and operating efficiency of large scientific facilities are the most important indicators to measure the speed and potential of a civilization's technological development. And at this moment, at least in the second-level civilization stage, Han Yang asked himself that he had almost reached the extreme.

During this period, as many as 500,000 Itar scientists taught human scientists through Zhixue.com - and also taught Han Yang, while working hard to lead the construction of various large scientific facilities, and at the same time conducting research on various scientific research tasks issued by Han Yang, and their lives were extremely busy.

But no matter how busy they were, no Itar dared to complain or dare to slack off.

The scene of Han Yang's brutal massacre of tens of thousands of Itars is still vivid. Are you trying to be cunning and sly at this time? Do you want to die?

Time is moving fast. In the blink of an eye, more than 20 years have passed since the liberation of the solar system.

In the past 20 years, the entire human civilization has flourished under the secret leadership of Han Yang.

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

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

One after another, new cities have sprung up, and transportation within cities, between cities, and between planets is convenient and fast.

A huge amount of materials and personnel are flowing between different planets and cities, injecting sufficient vitality into each city.

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

Medical costs have been greatly reduced, and free medical care has been achieved, so that people no longer have to go bankrupt for illness. The great improvement of medical technology has led to a rapid increase in people's average life expectancy, from only 180 years ago to 380 years now, more than doubling.

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

What Han Yang values ​​most is that after more than 20 years of continuous and large-scale investment, the scientific research power of mankind has finally been cultivated.

After Han Yang opened the new era doctoral graduate examination, a total of 4.3 million candidates who have received a complete education in the human civilization with a total population of about 22 billion signed up for the examination, and finally about 900,000 passed and obtained the doctoral title.

Next year, this number is expected to increase. It will only take about ten years for Han Yang to cultivate a scientific research system with a total number of tens of millions.

After having enough scientific research personnel, Han Yang's early research on basic physics theory and applied physics immediately blossomed into brilliant flowers.

One major scientific research project after another has made 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 this chapter)
