[Epoch Times January 10, 2022](Epoch Times reporter Di Rui compiled a report) The mainstream universe model believes that dark matter is an important component of each galaxy. However, new research has found that a galaxy about 250 million light-years away from Earth is as large as the Milky Way, and there is absolutely no evidence of dark matter.
In fact, in a study published in The Astrophysical Journal Letters in 2019, this group of researchers proposed that there are no traces of dark matter in six galaxies. Because this is very different from the mainstream cosmic cognition model, the researchers decided to collect more data for a more detailed analysis of each galaxy.
In this study published in Monthly Notices of the Royal Astronomical Society on December 14, 2021, the galaxy AGC 114905 was analyzed again, and there was still no trace of dark matter. This galaxy is 248 million light-years away from Earth and is located in the constellation Pisces.
Astronomers classify the galaxy AGC 114905 as a “dwarf galaxy”, which means that it has a lower brightness. This is because although its spatial range is about the same size as the Milky Way, the number of stars in it is only a few thousandths of the Milky Way. In other words, the distribution of matter inside such a galaxy is very sparse.
Mainstream theories believe that other theories alone cannot explain the distribution of various structures of all stars and galaxies in the universe. By introducing a concept of dark matter, all of this can be better explained. This mainstream theoretical model of the universe estimates that dark matter accounts for 85% of the total matter in the universe. But scientists don’t know what particles it is made of, so they collectively call it “dark matter.”
According to the dark matter theory, the sparsely distributed dwarf galaxies need dark matter to bring together the celestial bodies and various materials in the galaxy and maintain the shape of the galaxy. This study found that there was no evidence of dark matter in the dwarf galaxy AGC 114905, which surprised the researchers.
The study concluded that the data they observed showed that the pattern of matter movement in the galaxy AGC 114905 was completely the result of normal matter interaction.
One of the main researchers, astronomer Pavel Mancera Piña of the University of Groningen in the Netherlands, said: “When we discovered that there were no dark matter in six galaxies, they told us “Test it again.” Pina refers to the reaction of colleagues after their research results were published in 2019.
Pina said: “However, after 40 hours of careful observation, it has provided more conclusive evidence for the claim that this galaxy has no dark matter. This is of course our expected result, confirming that our previous measurements are correct.”
“The problem that now arises is that the theory believes that there must be dark matter in the AGC 114905 galaxy, but our measurement results found that there is no dark matter there. In other words, the difference between theory and observation has increased.”##
