What is China s first extremely deep underground laboratory used for? Why dig so deep?

In July 2019, Tsinghua University launched a project for underground laboratories, which is also the first major scientific and technological facility undertaken by an independent legal entity in China. As the world's deepest polar laboratory, the project will further consolidate China's scientific and technological foundation after completion, and at the same time promote China's independent innovation ability and international influence.

1. The world's deepest and deepest underground laboratory, jointly built by Tsinghua University and the hydropower development team in the Yalong River Basin, has been built at the mouth of the Jinping Mountain Tunnel in China. This basement was built in China for the study of physical experiments and the implementation of the "13th Five-Year Plan" scientific and technological infrastructure. After the completion of the project, it will become an important national innovation platform, mainly to lay the foundation for China's scientific investigation and popular science education.

The purpose is to consolidate China's scientific and technological foundation, promote independent innovation in science and technology, and then improve the quality of social development and lay a solid foundation for economic development.

2. The completion of the laboratory of the World Deep Earth Physics Experiment Center is mainly to study the knowledge of physics, especially the research of dark matter, and to explore the energy exploration of dark matter on the accelerated expansion of the universe through various studies such as astronomical gravitational lensing and microwave background radiation. This project has an important fundamental and cutting-edge effect on the research of new particles under the current Standard Model of Physics, and the research on dark matter is carried out in this laboratory, in which very low radiation SMS methods and technologies are developed, and provides platform support for cutting-edge issues such as particle physics research in China.

Third, in the future, we will build a number of experimental platforms within five years, because major breakthroughs in modern physics require some extreme experimental conditions, and the extremely deep underground laboratory just provides such a platform. To provide important research facilities for particle physics and astrophysics and cosmology. In the future, after the 13th Five-Year Plan, a number of experimental platforms will be built to collaborate on key problems and promote the development of the frontier of physics.

Among them, there are dozens of different functional laboratories including underground and aboveground, realizing a new breakthrough in dark matter tracking in China.

China's first and the world's deepest ultra-deep underground laboratory, "China Jinping Underground Laboratory", can be engaged in dark matter detection and related discipline research. Because one of the ways to find dark matter is to dig a large pit deep in the ground, and put precision instruments at the bottom of the pit to detect dark matter.

China's first extremely deep underground laboratory was used to store some of the ancient viruses that humanity had not been able to conquer. Because of digging so deep, if the virus breaks out, it can be isolated in time to prevent people on the surface from being harmed. The deeper underground is also conducive to freezing the storage of these viruses.

Away from normal human life.

This underground laboratory is used to detect neutrinos in space. Because neutrinos are very unstable and extremely difficult to capture, it is easier to capture neutrinos by building laboratories deep underground from the surface.

If dark matter exists, what is its role in the universe? The exploration of the universe and humanity is a very important milestone. With the development of science and technology, more and more scientific theoretical studies have found that dark matter is the most mysterious of all known substances currently known.

Why is it attracting so many people's attention?

The significance of the existence of dark matter is that it does not travel through electromagnetism and electromagnetic waves like light, heat, magnetism and other substances, but is generated through the interaction between particles and matter. There are so many interactions between particles, and there is no effect between dark matter and ordinary matter, but their properties are very similar. So, what does it really mean when dark matter doesn't exist?

Answer: People are trying to explain this problem with new particle technologies. Through this new technology, people can find more accurate information about the material world in the universe and understand the relationship between them more quickly**.

However, this situation can only be guessed and not confirmed by existing technology, so people have to pay more attention to the new situation of dark matter.

Dark matter has about 30 times more energy than ordinary matter. Its energy is around dark matter, while the energy of ordinary matter is only one-thousandth the mass of dark matter (about the mass of the universe). If they are produced in space, it may affect the entire universe, causing the entire universe to expand.

Why do we keep looking for dark matter? We know that there is a theoretical model framework for dark matter: dark matter comes from the gravitational pull caused by dark energy.

Scientists believe that humans may have been around for thousands of years, and that all of this is due to the damage caused by dark matter and its consequences. According to the current stage of the universe in which humanity is located, it is a very complex material world that includes all the energy states that we see. Dark matter affects all of our matter interactions, including mass as well as energy, leading to galaxies-star collisions, star collapses, and gravitational wave detection.

We humans may be affected in a variety of ways, some of which we are unaware of, but most of us are conscious, especially when things related to human beings themselves happen more.

At present, our economy is developing rapidly, and after becoming rich and well-off, in addition to filling our stomachs, we have turned more attention to the development of science and technology, including the improvement of comprehensive national strength, which makes us more capable of speaking in front of the world. So what is being studied in this 2,400-meter-underground, the world's deepest underground laboratory? Let's take a closer look.

This is called China Jinping Underground Laboratory, its depth reaches 2400 meters, its main technical support is the Tsinghua experimental team and the experimental team of Shanghai Jiao Tong University, mainly for the study of dark matter detection, that about this dark matter we ordinary people may not be able to contact in ordinary life, but when science and technology develop to a certain point, the detection of dark matter will further go to the public's field of vision, the current resource exploration has reached an unprecedented rich, Dark matter will be the next step we need to explore.

Therefore, the dark matter studied by the world's deepest underground laboratory, although it sounds very ethereal, but its actual role is very large, and the completion of this underground laboratory further shows that China is at the world's first-class level of science and technology, this most cutting-edge basic research direction, which has not been achieved by few countries in the world before, and we are just at the forefront.

Being able to detect dark matter further shows the advanced detection technology in China and the improvement of detection sensitivity, which is not only a great improvement at the social level, but also at the military level. Just as we were the first country in the world to embark on lunar exploration, this combination of signs proves once again that the lion of China will continue to rise rapidly.

The rapid development of science and technology also represents the peace of the country and the rich life of the people, only in a peaceful environment, we have the strength to continue to explore technology and the future, this dark matter that cannot be seen or touched in the universe, will become clearer and clearer under our further exploration.

There is no special research, but some experiments that require special conditions will be carried out below to make the experiment better.

Of course, it is studying the center of the earth, and the earth's center of the earth has not yet been explored, so it is vigorously developing this scientific research undertaking.

This underground laboratory in Sichuan is an important scientific research base in China, mainly researching physics and quantum, and providing important basic support for China's Tianyan.

This mysterious laboratory is working on a special substance. Dark matter particles, because this substance is so rare and difficult to detect, so they turned their attention to the depths of the earth.

In Liangshan, Sichuan, China, this laboratory looks relatively ordinary on the outside, but in fact, the machinery inside is relatively comprehensive.

The world's deepest underground laboratory is located in Sichuan, China, called the China Jinping Underground Laboratory, which is a frontier research laboratory for basic science. Although this laboratory has been announced, only the people who work in it know what it looks like, and the official only gives a simple model, which has no reference value.

The underground laboratory is located in Jinping Mountain, Yalong River, Sichuan Province, and the laboratory is very luxurious, with all the utensils.

The world's deepest underground laboratory is the Jinping Underground Laboratory of China, located in Jinping Mountain, Yalong River, Sichuan, with a depth of 2,400 meters, the laboratory is excavated from the side of the Jinping Mountain tunnel, 40 meters long, 6 meters wide and 6 meters high, buried deep underground, is an important research site for dark matter detection research in the fields of particle physics and astrophysics, neutrino experiments and other major basic frontier topics.

On December 12, 2010, "China Jinping Underground Laboratory was inaugurated and put into use, with a vertical rock cover of 2,400 meters, which is currently the deepest laboratory in the world.

The world's deepest underground laboratory has been put into use, with a depth of 2,400 meters, and China's first extremely deep underground laboratory, "China Jinping Underground Laboratory", jointly built by Tsinghua University and Ertan Hydropower Development Co., Ltd., has been put into use.
