As early as 2019, scientists discovered a giant "hole" near the Milky Way, and 200 million light-years away, a super-giant thing covering an area of more than 8 million light-years in diameter is surrounded by millions of galaxies.
Scientists immediately began to think about the source of this huge gravitational pull and began to investigate, but until now, they have not been able to give a definite answer to what this huge existence is.
Tens of thousands of galaxies are attracted.
Astronomers have found an astonishing phenomenon after analyzing the data of galaxies 200 million light-years away - tens of thousands of galaxies are all unfolding in a certain direction, which is not unfamiliar to us, because the Milky Way, as an ordinary planet, is naturally bound by other galaxies, bound by a certain gravitational force and will not drift at will.
However, the 8 million light-year diameter of the super giant "hole" attracted by the galaxy is only a few tens of thousands, if only tens of thousands of galaxies are attracted by a particularly large galaxy, but this is the number of galaxies attracted by a giant "hole", so astronomers have a strong interest in this, immediately carried out a detailed study of this huge existence, and finally came to an astonishing conclusion, that is, this huge existence has a huge gravitational attraction, Astronomers were able to come to this conclusion mainly because they discovered a special element helium when they searched for the cause.
This particular element of helium is a very common element in nature, and it was also an element produced in the early days of the Big Bang, but now this element is very rare, which means that once a large amount of this special helium element is found, then there must be a major astronomical mystery.
With the efforts of astronomers, they finally found this huge sense of existence, but when they found this sense of existence, they were also confused because of the huge sense of existence, because hundreds of thousands or even millions of galaxies were attracted to the same existence, what kind of strength does this existence exist to attract so many galaxies?
Therefore, astronomers have made detailed observations of this being, and finally found that this existence is not as we imagined, it is not a huge galaxy, but a giant "hole", but this giant "hole" is much heavier than other giant "holes", so there is such a large gravitational force, but astronomers still make detailed observations of this kind of being.
The source of great existence.
The overall shape of the "hole" is a bit like a huge star, and this "hole" will also be like a star, with a huge gravitational pull, and will swallow a lot of mass, but this "hole" does not look like a huge star at all, so astronomers after analyzing the structure of this "hole", they found that this "hole" is not a huge star, but a giant mass, this mass is called "extremely massive structure" by astronomers.
What is a "very massive structure"?
In the universe, because galaxies and galaxies have a huge gravitational pull, they will have a certain correlation between them, and this association can be explained as a "large-scale structure", and the "maximal mass structure" is also a special form of "large-scale structure", but the "maximal mass structure" because the mass of one of the galaxies is too huge, so when the galaxy swallows other galaxies, it will form a giant clump.
This situation is the "maximal mass structure" studied by astronomers, and the "maximum mass structure" will become a huge "black hole" after a certain period of time, just like ordinary stars, so astronomers also believe that this "maximum mass structure" may be a huge "black hole", and this huge "black hole" is also called "dark matter" by astronomers.
Why is this huge "black hole" different from ordinary "dark matter"?
This has to start with the definition of "dark matter", the so-called "dark matter" is not a real substance, but a virtual form of existence.
So why is there "dark matter"?
After the Big Bang, the matter in the universe produced a state, this state is the "early state", in this state, the matter in the universe is very thin, and the proportion of nuclear matter in it is very small, so when astronomers study the matter in the universe, it is difficult to carry out experiments, so many matter cannot be analyzed for its actual composition.
Therefore, when astronomers analyze this substance, they think that this substance is "dark matter", and the existence of "dark matter" is very mysterious to astronomers, so astronomers continue to look for traces of "dark matter" in the universe, and finally find that the "dark matter" of this substance is not a real substance, but a kind of nuclear matter produced in the early days of the Big Bang, so this substance is more difficult to analyze, but the existence of "dark matter" has also been confirmed. So what is the existence of this huge "extremely massive structure"?
The difference between the "maximal mass structure" and other stars is that their gravitational attraction and mass are very different, so when astronomers analyze this "maximum mass structure", they believe that this "maximum mass structure" may be an ancient "primordial black hole", and the "primordial black hole" has a very large gravitational force, so it can attract tens of thousands or even millions of galaxies at the same time, and the "primordial black hole" will eventually swallow more galaxies, so it will harm other galaxies in the universe.
However, this does not mean that this "primordial black hole" is the source of matter, because the "primordial black hole" is a very precious existence for the universe, so when astronomers study the "primordial black hole", they believe that the possibility of the emergence of this "primordial black hole" is that two huge stars swallow each other to form, but if this "primordial black hole" really appears in the universe, then it will cause great harm to the universe.
Therefore, after evaluating the safety of such "primordial black holes", it is believed that such "primordial black holes" do not appear in the universe, but what if a "primordial black hole" forms in a certain galaxy?
Causes of the formation of dark matter.
This is also a question that astronomers have been unsolved, and one astronomer questioned it at the time, and when analyzing the creation of this "primordial black hole", he thought that it may be the formation of ancient "dark matter", and this "dark matter" participated in tens or even millions of years, and finally formed a huge "extremely massive structure", but astronomers do not know the source of "dark matter".
Later, after studying the "maximum mass structure", astronomers analyzed the source of "dark matter", and finally found that in the birth cycle of stars, an ancient "dark matter" will be formed, and when this ancient "dark matter" forms a "maximum mass structure", a "dark matter" will be produced for tens of thousands or even millions of years, and finally a huge "maximum mass structure" will be formed.
The stars in the galaxies swallowed by the "megamassive structure" will not be swallowed, but will be reborn in the "black hole" formed by the "megamassive structure", so when the "megamassive structure" is studied again, astronomers have found that there is no "dark matter" in this "megamassive structure", but many stars with strong gravity, and in the stellar birth cycle, it will be confirmed, but astronomers still perform the time of this "dark matter" participation.
epilogue
This means that this "maximal mass structure" is still an unknown existence, but it may also be a "primordial black hole", and there are still many unsolved questions about this huge "maximum mass structure".
