Introduction: In order to express my thoughts in a comprehensible way, I used some of my own images, but I believed it necessary to use along with the essential images and descriptions of the “great ones”, always citing the authors of the said pictures and descriptions, that’s why I have to thank the authors for their work!

Many observing astronomers and astrophysicists deal with the existence of dark matter. 

I wrote about this myself, in my study entitled: https://astronomyknowhow.hu/en/dark-matter-and-dark-energy

Meanwhile the world and the science have progressed. 

What do we know about dark matter?

• It has gravity, which we are sure, we can detect it. (1. photo)
  
• The gravity of dark matter is not equivalent. The strength of gravity could be a one- to ten-times.
  
• Typically can be found in galaxies and clusters whose cohesive adhesive is the dark matter.
  
• When looking far into space with gravitational lens, dark matter creates special gravity magnifications.
  
• Dark matter also acts on visible matter, maintaining contact to it by gravity, but no direct effect on known matter is found.
  

The known Universe consist of:

• 22% dark matter,
• 5% the known matter, and
• 73% dark energy.
  

However, dark matter cannot be detected by any Earth-based human detection instrument. If the gravitational pull of dark matter exists, then there must be matter, too! Probably can be the detection instrument or method not appropriate for detecting dark matter. Scientists need to move forward to solve this problem.

Reflecting on the above, I came to the conclusion that dark matter exists indeed.

Material: consists of extremely small atomic particles, the small size of which and the quality of its material preclude optical detection. This quantum dark matter is not detectable with our current astronomical instruments.

The Universe is not an empty space! There is also a huge amount of extremely small quantum material in it, as I wrote about in my study https://astronomyknowhow.hu/en/the-universe-wont-cease-to-exist--what-happened-before-the-big-bang​

Origin:

As I wrote in my study, not after a series of events without precedent the Universe was formed by the Big Bang, preceded the exploding of an extremely large Black hole being formed in a special way from the dust of the Universe.

During the Big Bang, not only hydrogen and other precursors were formed, but also the quantum dark matter was formed, as an extremely fine powder of the Big Bang. Its material must be metallic, so it can create, hold together and glue the spiral galaxies and nebulas with its much stronger gravity. If dark matter won’t exist, spiral galaxies and nebulas would cease to be a unit, being burst in the Universe. Dark material is possible to be formed from the black holes as they constantly evaporate, losing material due to Hawking radiation. This evaporation can be the creator of a wide variety of dark materials, too.

The nonbaryonic dark matter can be:

1. neutrinos,
   
2. wimps - weakly interacting elements,
   
3. axions - elementary particles without electric charge and spin.

These are examined by the world's largest research institutes, but none of them have been isolated as having no connection with the known materials.

In Debrecen, the Atomki researcher Dr. Attila Krasznahorkai created the X17, 18 times heavier than the electron, which is a new Boson, the fifth natural force, which could be the dark matter. His research is recognized worldwide, although there are opponents, he is possibly candidate for the Nobel Prize.

Detection:

Dark matter can be observable, especially in dwarf galaxies, behaving as if it were a dark liquid, which, however, has an effect on the known matter by its gravity. According to my present information, its component is probably the neutralino, which behaves physically exactly as indicated by the research physicists. The main part of dark matter is a cold matter, in order to come into contact with visible matter, it must be heated up, to interact with each other. (Picture 1)

Dark matter is expected consisting of not only a single component, but known substances could be the components, consisting only of extremely fine, extremely small atomic, quantum fraction size particles. Studying of dark materials by atomic research, spectral analysis, or radio astronomy perhaps, should bring the result, probably to the composition of dark materials, I think. It could be conceivable the discovery of a so far unknown new material, by knowing dark materials.

Gravity, driving the Universe is completely separate in the fundamental interactions. It was found from the theme mentioned above, dark matter has significant gravitational effect, too. Thus the possibility arises that dark matter is an appearance form of gravity! But we do not know how gravitational attraction is spreading in the Universe!                           

Dark matter = Gravity?

The scattering of the Hyadok constellation began hundreds of millions of years ago and continues still today. According the recent researches the dispersion is caused by a collision of the giant mass of dark matters. Following from that dark matter must be real matter!

Main properties of Dark Matter:

The Origin of Dark Matter: As I’ve written in my study, it was not after a series of events without preliminaries that the Universe was formed by the Big Bang, preceded by an explosion of an extremely large black hole formed in a special way from the dust of the Universe.

Not only hydrogen and other precursors were formed during the Big Bang, but the same time also the quantum dark matter was formed, as an extremely fine powder of the Big Bang. Its material must be metallic, to be able to create, hold together and glue spiral-galaxies and nebulas with its much stronger gravity. Without dark matter, spiral galaxies and nebulas would cease to be a unit, by being dispersed in the Universe. https://astronomyknowhow.hu/en/dark-matter-and-dark-energy 

The formation of dark matter is possible from the black holes as they constantly evaporate, losing material due to Hawking radiation. This evaporation can be the creator of a wide variety of dark matters, too.

Non-baryonic dark matters can be:

• neutrinos,

• wimps - weakly interacting particles,

• axions - elementary particles without electric charges and spinning.

These matters are being studied by the largest research institutes in the world, but none of them have been isolated because they have no connection with known materials.

The Origin of Gravity:

As I’ve written in my study, it was not after a series of events without preliminaries that the Universe was formed by the Big Bang, preceded by an explosion of an extremely large black hole formed in a special way from the dust of the Universe. Not only hydrogen and other precursors were formed during the Big Bang, but the same time also the quantum dark matter and the gravity were formed. Gravity has an infinite range and the gravitational waves travel at the speed of light.

Without dark matter and gravity, spiral galaxies and nebulas would cease to be a unit, by being dispersed in the Universe. At the same time arises that such mysterious gravity’s properties are almost identical to those of the dark matter’s! Their main identity is that both of them are characterized by gravitational attraction. We do not know how they travel in the Universe, at or above the speed of light. It is conceivable that a form of dark matter is gravity, or conversely, a form of gravity is the existence of dark matter.

Gravity has a thickening, but it can only be detected by radio astronomy, known as ORC. The constellation Hyadok collides in the Universe with a giant dark matter or gravity that scatters it. Gravity occurs only as a mass, e.g. the galaxy has gravity (static). Dark matter has known properties, like holding the creating galaxy together and forms, and holds it together (dynamic), too.

Consequently, there first existed the material that the dark matter holds together and forms together.

Then develops its gravity. I consider the infinite gravity and infinite matter to be possible. If gravity is infinite, that is, (only its effect decreases squared in inverse proportion to distance), then dark matter is also infinite. But we only its gravitational effect perceive.

Gravity, driving the Universe is completely separate in the fundamental interactions. It was found from the theme mentioned above, dark matter has significant gravitational effect, too. Thus arises the possibility that dark matter is an appearance of gravity. However, we do not know how the gravitational attraction travels in the Universe.

Gravity is independent, it has its own class, and it cannot be combined with anything else.

If we know the mediating material of gravity, we can presumably know already a similar dark material, too. If there were the nature of gravity and dark matter, would it be just (a small step?) to know the dark energy that makes up 72% of the Universe!? Then we would also get to know the issue of dark matter and dark energy.

Dark energy has a repulsive force, its behavior is opposite to dark matter, which provides a cohesive, gravitational attraction. Dark energy has a repulsive force, dark matter is cohesive, but both work with a form of gravity, mediating.

Maybe “dark” is a false word, communicating only the fact that we do not know it, we don’t see it. So it would be important “to see”, perceiving all three of them: gravity, dark matter, dark energy, and knowing their mediating materials, too. However, it helps a lot that their properties are similar. What makes them the same and why are they larger in quantity to our present knowledge? Quantities may not be determined correctly and the correct determination of the ingredients is not 75-25-5%, they may deviate significantly. It may differ because in each case gravity is the unit of measure. So gravity needs to be examined at better. There may be several types of gravity, but if gravity is infinitely distant, it is part of the infinite Universe. It also determines the material and composition of gravity.

In fact, we should know the background material of the Universe, from which the mediator of gravity follows! I think the background matter of the Universe is the same as virtual matter, so that's what we should examine. Virtual matter is available, appearing sometimes, it turns into matter, so it can be investigated.Maybe the virtual matter is the mediating matter of gravity!

At the origin of the Universe: https://astronomyknowhow.hu/en/universe---explanation-of-the-infinite

I claimed that energy waves swept together the quantum matter in the Universe. This is how the known Universe was created. An infinite number of universes have sprung up in the Universe. There is a little chance that materials with the same atomic structure as our Universe would have been created in the others. Universes of completely different atomic structure and composition were created in the Universe that differ from those in the Mendeleev table. Maybe a new Mendeleev table will be necessary to create, supplemented with other materials and elements.

It will be a great miracle when the above will be proved that there is a universe with a completely different materials and physics. Moreover, it is not impossible that we are still part of it today, living in it, being here around us, e.g. in the form of dark matter and dark energy. The infinite, the universes, their material components, and their physics should certainly be examined in a different way from the above. Upon knowing this, the issue of dark matter and dark energy will also be resolved.

Maybe, as I wrote earlier, there is no dark energy, only the centrifugal force of our Universe rotating in a disk-like plane around its own axis causing its accelerating expansion. It is not impossible that a measurement method error from the redshift is thus interpreted as expansion. It is also possible that the mysterious path of light deceives us, as written in “https://astronomyknowhow.hu/hu/a-feny-rejtelyes-utja-a-vilagegyemben”.

The 95% of the Universe is still unknown. Black matter - black energy, how possible is the balance of the Universe if only the 5% of it, the known substance can we examine and see!?
