Ask where dark matter is hiding. What is the color shape. Cancer is not known

Dark matter is a substance that cannot be observed, does not interact with known physical means, but has mass.

Because it cannot be observed by any means known to humans (including but not limited to optics, various electromagnetic waves, and magnetic fields), dark matter is a substance with no color and an unknown shape.

The only reason for the existence of dark matter is that the distribution of galaxies in the universe does not conform to gravitation and relativity, so scientists have conjectured a kind of matter that has mass (i.e., gravity) but cannot be observed--- dark matter.

For the time being, there is no hypothesis of dark matter and the color and traits of the gods.

There is a hypothesis that 95% of the energy in the universe exists in the form of dark matter, and the matter we can see is exactly the substance corresponding to it, so the existence of dark matter cannot be observed with various visible instruments, and only through the effect of the interaction between dark matter and other matter can be imagined that there is such a thing, there is a hypothesis that dark matter exists in the form of antimatter, and there is an opposite earth in the depths of the universe, and there is also a "you" that exists in opposite energy.

It's a bit mysterious, but the mystery of science is its unpredictability, isn't it?

Computers would have come to mind in the 18th century? Plane? Hey.

This is a question that scientists have not solved so far, and dark matter, which has only been speculated by some people, has no conclusive evidence.

The universe is large**, and according to the general understanding, it should be constantly decelerating. Just like the everyday**.

But in fact, on the contrary, all the celestial bodies in the universe are constantly moving away from each other at an accelerated speed. This is the conclusion of Hubble's observation of the redshift phenomenon.

Why is this happening? It's really puzzling. But it is certain that this must be the constant replenishment of the universe with extraordinary energy and matter. Otherwise, it is absolutely impossible.

Well, this foreign matter or energy. And where do they come from?

According to calculations, the universe, visible celestial bodies and, of course, black holes. Because black holes, although invisible, can calculate the impact of their presence on celestial bodies.

The mass of all the celestial bodies that we can see is only about 10 percent of the entire cosmic matter.

In other words, a large amount of matter in the universe is invisible. We simply don't detect their existence.

People call these substances "dark matter".

These dark matter dominate almost the entire universe.

Now, the question is, what exactly is "dark matter"? Where are they hiding?

Below, just guesses. Because it will never be possible for humans to verify and examine these mysterious substances.

Can you guess that?

"Dark matter" comes from the 13.8 billion-year-old remnants of the universe. That is, the "delayed core" left over from the universe and did not have ** at that time.

That is, after the decline of the previous universe, the "cosmic eggs" left behind are uneven. So, it's not an overnight success. A large amount of wreckage was also left behind, and there was no time for the eruption at that time.

Rather, it is constantly erupting in the later stages. It can also be called the "post-cosmic great**". In this way, we continue to deliver matter and energy to our universe.

This is where "dark matter" comes in.

Why can't humans observe them?

Because, the "cosmic egg" left over from the previous universe is actually a super black hole.

That super black hole is not the same universe as our universe. In other words, that universe and our universe are not in the same time and space. So, we can't perceive it at all. This is because we can only observe and study celestial bodies in the same time and space as us.

But when those delayed nuclear eruptions, matter came to our universe. Causes an accelerated expansion of celestial bodies.

There is a type of celestial body called a "quasar". It is not a star, nor is it a galaxy. We are all very far away, all around 10 billion light-years.

The most striking feature of quasars is that the amount of energy they release is particularly huge. Far beyond the energy of ordinary galaxies.

So what is a "quasar"?

The quasar may be the later stage of the remnant orange barrage left behind by the universe. That's why it's got a lot of energy.

This should be the ** of "dark matter".

Dark matter "is likely to be the late eruption of a delayed nucleus that is a big cosmic one." So, the amount is huge. So, we can't see and we can't observe.

In this way, the mystery of "dark matter" and "quasars" can be better explained.

What do you think?

In 1933, Zwicky, a Swiss astronomer at the California Institute of Technology, discovered a strange phenomenon while studying galaxy clusters: galaxies seemed to move too fast relative to the center of the galaxy cluster. A galaxy cluster is a collection of galaxies that can contain hundreds of bright galaxies that are bound by a common gravitational field.

The cluster of galaxies that Zwicky is studying, known as the Comae Cluster, is located 300 million light-years away from the Milky Way.

Zwicky's colleague Smith used the best telescope in the world at the time to collect the velocities of the member galaxies in the galaxy cluster. Using gravitational theory, astronomers can infer the total mass of a galaxy cluster from the speed of its motion, and the faster the galaxy moves, the stronger the gravitational field that binds them, which means that the total mass of the galaxy cluster is greater.

Zwicky deduced from the speed of galaxies that the mass of the galaxy cluster was too large, hundreds of times more than the mass of the galaxy. Throughout his life, Zwicky never lacked the passion and genius for naming something new, and he soon named the hidden mass in the galaxy cluster "dark matter". However, due to the lack of other independent observations, the concept of dark matter was mentioned from time to time in the next three decades, but no one took it seriously.

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 elaborate perfectly on the relationship between mass and space, when the mass reaches a certain level, the quantitative change leads to qualitative change, and the depression of space intensifies, resulting in the degree of attraction of the river system exceeding the gravitational force caused by its actual mass.

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

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

What is dark matter? How dark matter was discovered, hear what scientists have to say.

Invisible and untouchable dark matter, how scientists discovered it, what it is.

Dark matter is invisible matter because it violates Newton's laws, and based on this, dark matter was discovered by scientists.

Astronomers observed that the extra gravitational pull of the celestial bodies to move faster when the stars moved, but they did not know what kind of material produced the extra gravitational pull, so they named it "dark matter".

Dark matter, which is essentially a substance made up of particles other than our elementary particles, does not emit visible light and cannot interact. People found it because of its amazing mass.

Latest Research Results: Dark matter is an artifact brought about by the vortex effect of gravitational field space.

Standard Answer: Dark matter is a substance that exists in the universe and cannot be observed by any known means of human beings. The only evidence of the existence of dark matter, which is the anomaly of gravity.

Therefore, dark matter does not have any color, and in terms of shape, dark matter should exist in the form of elementary particles, so there is no such thing as shape.

Personal answer: Dark matter is a hypothesis, and when the scientist Duan Lu Shijia observed the universe, he found that the distribution of galaxies in the universe did not match the formula of the theory of relativity. In order to make the model of the universe conform to the formula of the theory of relativity, scientists have hypothesized a dark and bright matter, which cannot be observed by any known means of human beings, nor does it react with any matter in the universe, how it is produced in the universe is also a mystery, the reason why scientists think it exists is because the reality does not match the theory.

In order for reality not to be wrong, there must be a mass that we can't see, where gravity is created.

My personal opinion is that dark matter, dark energy, does not exist at all. However, it is the imperfection of the current scientific theories of mankind that leads to the inconsistency of the observation data with the theory. It's as ridiculous as the scientists of yesteryear came up with the "ether".

Astronomers began to realize the existence of invisible dark matter in the universe in the 30s of the 20th century. In 1933, Swiss astronomer Fritz Zwicky observed the Comae cluster of galaxies, which is 100 million light-years away from Earth and consists of more than 3,000 galaxies.

He used two different methods to measure the mass of galaxy clusters. The first method is to analyze the velocity of a large number of galaxies, which can be used to estimate the mass of the cluster indirectly because the velocity is related to gravity. The mass obtained by this method is called "mechanical mass".

Another way is to estimate the mass by the brightness of the galaxies within the galaxy cluster, because the more massive the star, the brighter it is. The resulting mass is called "photometric quality". It is said that the mechanical mass and the photometric mass should be similar, but the actual result is that the mechanical mass is about 400 times higher than the photometric mass!

In other words, the vast majority of mechanical mass is a substance that we cannot see (do not emit light). Without the action of this part of the "invisible matter", the gravitational pull of this cluster of galaxies would not be enough to bind the galaxies in it as it is now.

In the 70s of the 20th century, American astronomer Vera Rubin used the telescopes of the Kitt Peak Observatory and the Lowell Observatory to observe the Andromeda galaxy about 2.5 million light-years from Earth. She used the Doppler effect to measure the velocity of the gas revolving around the center of the galaxy at different radii. Supposedly, the closer to the center, the greater the gravitational pull, and the faster the movement should be to generate enough centrifugal force to counteract the effects of gravity.

Just like the closer a planet is to the Sun, the greater the rotational speed. But Rubin also discovered a strange phenomenon: gas at different distances from the center of the galaxy rotates around the center at about the same speed.

She looked at other galaxies and found the same. As a result, Rubin argues that there is material in the universe that we cannot see, providing gravity for the gas scattered throughout galaxies.

In the 80s of the 20th century, scientists officially proposed the name "dark matter". It is now generally accepted that galaxies account for only a few percent of the mass that makes up galaxy clusters, the intergalactic medium accounts for about 20 percent, and dark matter accounts for 70 to 80 percent. The so-called "invisible" of dark matter does not mean that it is not visible in the visible light band with our naked eyes, but also means that no matter what wavelength electromagnetic waves are detected, such as infrared, ultraviolet, X-rays, gamma rays, etc., it cannot be seen.

That is, dark matter does not emit any band of light.
