What is dark matter and what is the use of studying it?

The development of science is always advancing, especially for the exploration of the universe, every country has made a lot of scientific and technological progressAnd we will hear the term dark matter in science, and many people wonder what is dark matter and what is the use of studying it? To put it simply, dark matter is a matter that cannot be seen in the universe, and studying it will have a qualitative effect on the speed of spacecraft, let's analyze it.

First of all, at the beginning, scientists used knowledge to calculate the mass of the universe and obtained the first data, but then they actually added the mass of the matter found in the universe to get the second data, but in comparison, the second data is one-third less mass than the first data, which makes people very puzzled, these lost one-third of the mass ran to the first, so there is a proposal of dark matter, scientists believe that there is a substance in the universe that we can't see, But they have a lot of mass and energy, and there are many theories that can prove the existence of dark matter, but from a practical point of view, it is still not found.

But the study of dark matter will inevitably be of great significance, the fundamental reason why the current space exploration is slow is that the speed of the projector cannot reach that level, and if you want to have a qualitative improvement, you need to change the fuel, and scientists believe that dark matter is a good material, with terrifying energy and the volume is not large, if dark matter is used as fuel, the speed will inevitably be qualitatively improved.

At that time, maybe you can really find a second planet suitable for human habitation, this is a very important thing, although the current earth has a lot of resources, but it has been consumed a lot by humans, plus the destruction of the environment, it is difficult to regenerate resources this time, it is even more difficult, so finding a second planet suitable for human habitation is what all countries are doing, but the speed of the aircraft cannot be improved, all this cannot be achieved.

Dark matter is a matter in the universe that is invisible to the naked eye, and at the same time, dark matter is very heavy and dense. Studying it is essential to explore the universe and master the core energy of the universe.

Dark matter is a kind of matter that exists in the universe but cannot be seen, and the study of dark matter can explain many irrational phenomena in astronomical observations.

Dark matter is a substance that cannot be observed through electromagnetic waves, and it is also a very, very small substance. Studying it has many functions, and by studying dark matter, we can discover the composition of the universe.

Invisible matter in the universe does not reflect light, does not react with electromagnetic waves, and cannot be observed by astronomical telescopes. Its existence is debatable. Studying it can shed new light on the universe.

Dark matter is an invisible substance that may exist in the universe proposed by Zheng He in the theory, which may be the main component of the matter in the universe, but it does not belong to any of the substances that constitute the visible celestial bodies.

This refers to an invisible substance, and this thing is an important part of the universe, which is why this happens.

Dark matter actually refers to a substance that is still not understood, although it is not understood, but it is a substance that does exist.

On the earth where we are trying to survive, there are many organisms, and at the same time there are many things that we can not understand, the proper noun dark matter firmly believes that you have all heard, in fact, dark matter is a general term for a class of things that exist in the universe, because we are not clear about the relevant knowledge points of the substance, so it will be called dark matter, dark matter is a proper noun that we have summarized through long-term exploration in community practice activities, Let's actually analyze it.

We all know that everything in the sky and earth on the balloon has its own name, and the occurrence of every thing is an element in it, and in many cases, we can not effectively understand many things that happen on the earth, such as many inexplicable substances formed in the universe, which we cannot understand, so many people will classify this kind of matter as dark matter, in fact, this is just a general term, and does not really refer to a certain substance.

Dark matter is often discovered, that is because the level of science and technology is getting higher and higher, biologists have completed a large number of scientific experiments and their continuous research to find that there is indeed such a substance on the earth, at the beginning of the process is also to cause suspicion of this kind of substance, through the development trend of the trend, finally learned that this is what we often call dark matter.

In fact, we can now grasp a lot of dark matter items according to the information technology of the network, and the information on the Internet now shows that dark matter does exist, just that the actual characteristics of dark matter are basically the same at the current level of scientific and technological progress. If you look at it carefully, you can find that dark matter can mainly show many characteristics, and we all know that there are four kinds of forces that are common in the development of people's natural society, and in them there will be attraction and interaction forces, etc., which can also show that the earth is an electromagnetic field, because according to the song, it has this kind of characteristics and characteristics, even if it is generated around us every day, but we are not aware of it.

This is a newly discovered matter in the universe, very large energy, there are many life forms, we have no way of knowing, is the biggest mystery in astrophysics at present, it was discovered by Hawking.

Dark matter is matter that is smaller than electrons and photons. It is because scientists discovered that there are things smaller than electrons and photons when they were researching, so they discovered the existence of this substance.

This is a substance in the universe, a substance that cannot be well observed, but still exists, which is determined through some calculations, through the study of the universe.

Dark matter has the greatest impact on celestial systems in terms of "gravity".

It is theoretically proposed to be an invisible substance that may exist in the universe, which may be the main component of the matter of the universe, but does not belong to any of the known substances that constitute the visible celestial bodies. The suspected violation of Newton's gravitational attribution found in a large number of astronomical observations can be well explained by the assumption of the existence of dark matter.

Modern astronomy has shown that dark matter may exist in galaxies, star clusters and the universe in large quantities, and its mass is much greater than the sum of the masses of all visible celestial bodies in the universe through observations such as the motion of celestial bodies, the phenomenon of Newton's gravitational attrition, the gravitational lensing effect, the formation of large-scale structures in the universe, and the microwave background radiation.

Combined with the observation of the anisotropy of microwave background radiation in the universe and the standard cosmological model (CDM model), it can be determined that dark matter in the universe accounts for 85% of the total mass of all matter and the total mass energy of the universe.

Properties:

1) Dark matter participates in gravitational interactions, so it should have mass, but the mass of individual dark matter particles cannot be determined.

2) Dark matter should be highly stable, and since there is evidence of darkness at different stages of the formation of the structure of the universe, dark matter should be stable on the time scale of the age of the universe (10 billion years).

3) Dark matter basically does not participate in electromagnetic interactions, and the interaction between dark matter and photons must be very weak, so that dark matter basically does not emit light; Dark matter is also largely not involved in strong interactions, otherwise the process of primordial nucleation synthesis will be disturbed, and the abundance of light elements will be altered, which will lead to inconsistencies with current observations.

4) Through computer simulation of the formation of large-scale structures in the universe, it is known that the speed of dark matter should be much lower than the speed of light, that is, "cold dark matter", otherwise the universe would not be able to form the observed large-scale structure under the action of gravity.

5) Synthesize these essential attributes. It can be concluded that dark matter particles do not belong to any kind of elementary particles known to us. This poses a challenge to the highly successful Standard Model of particle physics.

Dark matter is a dark cosmic substance that cannot be seen or felt by the human eye. The study of dark matter allows human beings to discover dangerous celestial objects in the universe in time, because black holes are dark matter, and if black holes are found to appear near the earth, it may be dangerous.

Figuring out the composition and properties of dark matter will fundamentally change the future of human life. Just like quantum mechanics more than 100 years ago, the study of dark matter will make revolutionary breakthroughs in energy, life science and technology, climate, environmental protection, communications and other fields, and will make more contributions to the research of fundamental particles, controlled nuclear fusion and many other fields of the Large Particle Collider, and affect people's future scientific and technological life.

Dark matter is an invisible substance that may exist in the universe theoretically, and the average density of the universe can be estimated for human beings, and the future development trend of the universe can be seen, which can reflect the future development trend of the earth.

In cosmology, dark matter refers to substances that do not emit electromagnetic radiation on their own or interact with electromagnetic waves. They cannot be directly observed by humans through any of the existing observation tools, and can only be known about the existence of a large amount of dark matter in the universe through the effects of gravity.

Dark matter (also known as dark matter) refers to matter that cannot be studied by observing electromagnetic waves, in other words, does not interact with electromagnetic forces. At present, people can only know or discover the existence of a large amount of dark matter in the universe through the effects of gravity.

The earliest evidence for the existence of dark matter** is the observation of the rotational velocity of globular galaxies.

Modern astronomy has shown through gravitational lensing, the formation of large-scale structures in the universe, microwave background radiation, etc., that the part we currently know, that is, the baryon (plus electrons), roughly accounts for 4 of the universe, while dark matter accounts for 23% of the universe, and 73% is a dark energy that causes the accelerated expansion of the universe.

The existence of dark matter can solve the inconsistencies in the big theory, and it is also very critical to the formation of structure. It is likely that dark matter is made up of a new particle (or particles) outside of the Standard Model of particle physics. The study of dark matter (and dark energy) is an important topic in modern cosmology and particle physics.

The study of dark matter helps to understand the total mass of the universe, and when the total mass of the universe is greater than a certain value, the universe will shrink under gravitational force in the future, returning to the singularity of the big **.

When dark matter was first proposed, it was just a product of theory, but now we know that dark matter has become an important part of the universe. The total mass of dark matter is 6 times that of ordinary matter, accounting for 1 4 of the energy density of the universe, and more importantly, dark matter dominates the formation of the structure of the universe. In this way, the study of dark matter can elevate human development and human problems to an unknown field, and then we can live in the era of science fiction, but so far dark matter is still a field of exploration, and it is difficult to say what role it will be.

But personally, I think that this should belong to the field of energy research, such as the beginning of the discovery of fire by the primitive people.

China will either develop rapidly in science and technology before I die, or the human race will become extinct!

The study of dark matter has gone beyond general relativity. Gravitation and quantum mechanics. It will also bring about a revolution in cosmology.

Studying dark matter will understand how the universe came to be. How did humans originate? How does the universe work?

The study of dark matter has also influenced medicine and biology, and humans can use dark matter DNA to develop new drugs** diseases. The application of dark matter will be in technology and cosmology. Medicine.

Biology. Astronomy and physics in several fields. The immeasurable impact on human civilization, of course, is huge?
