In recent days, for the first time, researchers from an international team of researchers simulated the formation of galaxies without considering dark matter, and the results show that the galaxies produced in the calculations are similar to what we actually observed. The findings will be published in the astrophysical journal.
Today’s standard cosmology model sits on the basis of general relativity, which has been a great success in interpreting cosmic observational data. However, dark matter and dark energy have not shown the “true body” in this theoretical framework. So it was suggested early by some scholars that general relativity might not apply on a large scale before it was wrongly presented with these nihilistic substances. As a result, many revised theory of gravity has emerged, such as the modified dynamics (MOND) theory proposed in 1983, which does not require the introduction of dark matter to explain many of the properties of galaxy dynamics.
This time, the researchers used the MOND theory. Starting with gas clouds hundreds of thousands of years after the Big Bang, the researchers simulated whether galaxies would form in the universe and which ones would form. “The simulations form almost all the other large galaxies we know, including rotating disk galaxies like the Milky Way. “One of the authors of the paper, Dr. Krupa, a professor of astrophysics at the University of Bonn in Germany, said.
Does this confirm the existence of dark matter in the universe? Clearly, it is too early to draw such a conclusion. Krupa stressed that the researchers have so far made very simple assumptions about the original distribution of matter and the early parameters of the universe. “We now have to repeat the calculations and incorporate more complex influences. Then we’ll see if the MOND theory really explains reality. “
