What is Dark Matter? Can it be observed with the naked eye?

The first thing to say is, what is dark matter.

As the name suggests, it is the substance that does exist in the universe but is invisible. The matter of which it is composed is not itself the substance of the celestial bodies that we can see. But it may well be the main substance of the entire universe. Through a large number of astronomical observations, and the law of gravitation.

Microwave background radiation, the formation of large-scale structures in the universe, and so on. The reason why dark matter is called dark matter is because it cannot be observed with the naked eye, because it has no effect on our real world, and can only be detected by instruments.

Dark matter is divided into useful and useless, of course, most of the dark matter is useful, dark matter as the sun's fuel to consume a part, as an energy source is to be burned by the sun, after the sun burns, the exclusion of burning matter, is space junk.

The material that falls from space is a meteorite. Meteorites are divided into iron meteorites, metal meteorites, and everything that falls is a treasure on earth.

Schrödinger's cat in quantum mechanics.

Tell us, there are observers.

The existence will make the life and death of the cat certain, and the possibility in the universe will be certain. The existence of human beings is essential to the universe, no one is unconscious, the universe is full of possibilities, and it will return to a state of chaos and undivided. Just as the memory of a computer can be 0 and 1, when the possibility exists, the disk is also empty, and it is the constant consciousness of people that makes the world more certain and colorful.

As people's ability to observe continues to improve, we can explore more and more things, and the unknown is dark matter, and there is less and less space left in the universe. Until one day, we recognize everything, and the universe has become a fixed small blessing from a world of possibilities.

The world, the memory of the universe has been used up! It's time for the universe to die! At that time, it will be restarted, and in another reincarnation, are you still willing to upgrade so quickly?

Dark matter scientists have proposed that it is an invisible substance in the universe, which cannot be observed by the human eye and does not belong to any of the substances known today.

Dark matter refers to substances that do not emit light or are electrically neutral in the universe, and they can only be measured by optical instruments and cannot be directly seen by the naked eye. If dark matter is scientifically answered, it is a substance that cannot interact with magnetic fields, so its existence can only be measured by gravitational induction. And the data shows that there is a lot of dark matter in the universe.

Dark matter cannot be observed with the human eye, which is the substance contained in the celestial bodies and is also the most important substance in the universe.

Did you know that more than 80% of the mass of the universe is unknown? The very small part we know is made up of planets, stars, including our human planets, but most of the universe is made up of unknown masses. What exactly is this unknown mass, because it has never been directly detected, is a major problem facing physicists today.

Although this unknown substance has never been detected, it does have a name: dark matter.

But wait, how do we know it's there if it's never detected?

Based on the observations, astrophysicists found that, according to what is known"Bright"According to the calculation of matter, galaxies are spinning much faster than expected, that is, there should not be enough gravitational pull in the glowing stars to bring galaxies together. However, galaxies rarely disintegrate, and it's clear that there are other gravitational sources that bring everything together.

This mysterious substance is known as dark matter.

But what is dark matter?

Over the years many particles have become candidates: axons, gravitons, etc., but the most theoretically promising particle at the moment is still WIMP, that is, weakly interacting massive particles. "Weak interactions"is so faint that it is difficult to detect.

Here's a picture**: the solar system and its planets, like the Earth, bathed in a faint halo, fly around it, occasionally interacting with the nuclei of ordinary matter.

Of course, in order to ** what she really is, scientists have made a lot of efforts, trying to be able to detect it in underground laboratories built around the world, and in the Large Hadron Collider"Manufacturing"It is similar to being created in the big **. So far, all these attempts have failed, and dark matter remains as elusive as ever.

What if it's more elusive than expected or its properties can't be discovered by traditional human search or search methods? Recently, the scientific community has proposed a new idea to expand the detection parameter space, especially low-mass dark matter particles, which has greatly improved the detection sensitivity.

1.Dark matter is a scientific hypothesis that has been proposed to explain the speed at which galaxies rotate, and there is already considerable evidence that dark matter exists. 2.

Dark matter itself is not an ordinary matter, not a substance that we are familiar with involved in electromagnetic interactions, so it is difficult to detect. If humans can easily find dark matter, it is not normal. 3.

We still don't know what kind of substance dark matter is, so we can only come up with theories that we can continue to eliminate and confirm through experimental observations.

Dark matter refers to an invisible substance that may exist in the universe; At present, human beings use the correlation effects of astrophysics to indirectly detect dark matter with some knowable matter.

Dark matter is matter smaller than photons and electrons; At present, human beings are using relative satellites, space stations to build probes, as well as astrophysical related effects, as well as some large colliders, so as to effectively detect dark matter.

Dark matter is the opposite of visible matter, that is, matter that does not participate in electromagnetic interactions, neutrinos are a kind of dark matter, and the well-known black hole is actually a kind of dark matter. But these two common dark matter only account for 1% of the total amount of dark matter we have speculated.

At present, dark matter can be observed by the mass of galaxy clusters, the rotation curve of galaxies, the observation of gravitational lensing, and the cosmic microwave Beijing radiation.

1. Dark matter is observed by the mass of galaxy clusters. The mass of a galaxy cluster can be calculated in two ways: photometric mass and kinetic mass.

Theoretically, the masses of galaxies calculated by these two methods should not differ much, but in fact, it is inconceivable that the masses of galaxies calculated by photometric masses are much smaller than those calculated by kinetic masses. This illustrates the fact that there are luminescent matter and non-luminous matter (dark matter) in the universe, and the amount of this dark matter is much greater than the amount of luminous matter.

This is evidence for the observation of dark matter.

2. Dark matter is observed using the rotation curve of galaxies. Theoretically, the farther away the planet is from the center of the galaxy, the slower the rotation, but in fact, the rotation speed of the planet at the outer edge of the galaxy is almost the same as the rotation speed of the planet near the center of the galaxy, in this case, if it is not attracted by some invisible matter, these high-speed rotating planets at the outer edge will be thrown out of the galaxy by centrifugal force, in fact, this does not happen, so this means that there is some kind of dark matter, so this is also an important dark matter observation.

3. Dark matter is observed through gravitational lensing. The mass distribution of galaxies observed by gravitational lensing is wider than that of visible matter reflected only by X-ray signals, and it can be seen that visible matter is only a part of the mass of galaxy clusters, and there is a large amount of invisible dark matter in galaxy clusters.

4. Observation of dark matter with cosmic microwave background radiation. Cosmic microwaves are the light left behind by the universe, and these lights have filled the entire universe. By detecting these lights with sounding satellites, you can see a map of the distribution of these lights, which can lead to the observation of the composition of various substances.

As a result, the proportion of dark matter is much more than five times greater than that of visible matter.

What humans call dark matter is the dark existence of the invisible body of the soul of the universe! The soul is intangible and forms visible form from everything it transforms. But the body of all things is so different from the body of the soul that the soul cannot know for itself.

As far as human life is concerned, the soul reflects the magnitude of wisdom, which is only reflected in the physiological functions of different physiological organs and different physiological systems. And human cognitive ability, like all living things, is related to external things, except for some senses that reflect their own physiological changes.

In addition, all life processes in the human brain are determined by the problems and objects around which life revolves. While a few can think and explore the performance, this is only a limited relative knowledge of what is arranged and determined! So, all the problems in the course of human life are determined by the human brain.

The same is true of human-made computers, which can only achieve limited functionality in programming with limited human knowledge. The difference is that the computer mechanically exhibits the function of intelligent numbers to calculate data in the form of a physical machine. However, human beings embody more flexible and changeable life functions in a more complete intelligent life form.

For computers, consciousness is the recognition function of a computer program. For humans, consciousness is the functional reflection of the brain and soul to recognize sensations.

Human behavior, physiological functions, and life phenomena are not just simple manipulations of the soul in the body, in fact, the soul and each person's life are completely integrated, harmoniously deduced. Therefore, man is not the so-called dark matter, but only the so-called dark matter, the soul body, which exists in the manifestation of human life forms. If the volume of the soul body that embodies wisdom is equal to the volume of a person, that is to say, the volume of the soul body that embodies wisdom is equal to the volume of the soul body of every cell of a person, then man will fully realize the reality of his life.

You know that there is dark matter in your life. This is the future of the new meaning of immortal humanity. But, in any case, for today's human beings, it is impossible, because nature dooms human beings to be inadequate, and it is impossible for them to know the truth of life!

Even Lao Tzu, Shakyamuni, Jesus, and other so-called saints, who were given the mission of the realm of prejudice and the hypothetical background of prejudice, are impossible to know!

Dark matter means that there is a substance in the universe that we cannot detect, and this substance exists in the process of the universe and has a certain efficacy, but we cannot observe it with the naked eye. Because this substance is a kind of energy, it may exist in every detail, but we cannot detect it in the operation of this process.

The so-called dark matter refers to the soul, which cannot be seen or touched, and is an invisible body; Dark matter is intangible, belongs to the scope of human cognition, and cannot be touched, and dark matter only causes physiological reactions to human senses, not real touch.

Dark matter refers to objects that do not emit light in the universe, and the reason why human beings cannot find dark matter is because with the current level of science and technology, this problem cannot be solved, and scientists are still investigating, so we must look at it rationally.

Dark matter refers to a very abstract substance, which has a close relationship with the universe, mainly in the form of life, because dark matter still has many mysteries, and human science and technology cannot achieve such a purpose.

Dark matter is an uncharged substance that is smaller than electrons and photons, and dark matter is no longer available because it is theoretically an invisible substance. So it's not easy to be found by humans.

Dark matter is not discovered, but speculated (speculated).

To date, dark matter has not been discovered.

Dark matter astronomers observe the starry sky and discover an abnormal aggregation of rivers in the universe that exceeds the coefficient of gravitation. In the spirit of the habit of creating a substance that cannot be discovered by humans at once when reality does not correspond to theory (the previous product of this habit is the famous ether), scientists speculate that there is a substance in the universe that cannot be observed by humans, does not have any coupling with electromagnetic waves, and only has gravity. Because this substance cannot be coupled (interfere with each other) with electromagnetic waves, it is named dark matter.

Later, when astronomers observed the movement of stars in the Milky Way, they were surprised to calculate that the movement of celestial bodies in the Milky Way was not affected by dark matter at all. In order to maintain the existence of dark matter, astronomers have announced that dark matter exists in the form of a halo around the river system, and the dark matter halo carefully attracts other river systems, and at the same time, it is more careful not to affect the operation of celestial bodies inside the river system.

And the latest news, astronomers have high hopes, is sure that the instrument that can detect dark matter (the Large Underground Xenon Dark Matter Experiment (LUX)) has detected nothing--- in my opinion, Dongdong, which does not exist at all, certainly cannot detect it.

Let's talk about my personal understanding of dark matter.

Dark matter simply does not exist, and there may be two reasons for the abnormal aggregation of river systems.

1 The theory of relativity does not explain the relationship between mass and space perfectly, when the mass reaches a certain level, the quantitative change leads to the qualitative change, and the depression of space is intensified, causing the river system to be attracted to a degree that exceeds the gravitational force caused by its actual mass.

2 Perhaps there is something outside the universe that has an effect on the universe.

PS: The term extracosmic is very unscientific, I know.
