Spiral galaxies suggest a mysterious interaction with ordinary matter

The standard cosmology model can boast of many successes. It depends on what is in the equationsEinstein A standard of Lampta (2) It is nothing but popular in ancient Greece Cosmological constant Of Einstein. Acts denselyEnergy That’s why we talk about beingDark energy In Standard model. It is further assumed that this energy acts like a Pressure Hatred, which accelerates the expansion of the observable universe for billions of years, does not differ in that it is more and more dominant in terms of matter, because it is not diluted. Gas Expanding particles.

Now let’s talk about material contentThe universe Precisely observable. Within the framework of the standard cosmological model, it dominates Black material Accelerators or detectors are thought to contain particles never seen before on Earth, and can only interact with static baronic matter and gravity alone. It is also almost necessary to calculate the properties of this material Cosmic radiation And very simply balance Constellations.

However, the standard cosmological model (with CDM is called ΛCDM Cold dark matter, I.e. “Gold Dark Matter”) is not correct, and this leads to inconsistencies and obvious inconsistencies in the test, which will undoubtedly need to be slightly corrected, rather than completely ruled out. Thus, the difference of opinion between the two estimates of the famous constant of the Hubble-Lemitre law relating to space expansion feeds the thinking of those who think so. Einstein’s standard May not be very stable.

Similarly, problems with properties Dwarf galaxies Satellites of large galaxies claim that there is a misunderstanding between dark matter and ordinary matter, perhaps even between dark matter particles.

The halo of the growing dark matter

Most recently, however, a group – mainly made up of researchers School International Superior de Study Avansati (Cissa) In Italy, Gauri Sharma, Pavlo Salusi and Glenn van de Wen – published the results of their work with an article in the prestigious magazine. Astronomy and astronomy.

The Astronomers Meticulously observed the contents of about 300 large dark objects Spiral galaxies As Milky Way And Andromeda, does a kind Goring In our past, almost 7 billion years ago.

Just like their predecessors Vera RubinThey measured speeds Movements From Stars And Clouds OfHydrogen The atom can extend beyond the visible edges of these spiral galaxies, in particular The popular line is 21 cm. These movements represent balance and distribution Masses Hidden, precisely the dark matter, unless the laws of astronomy are modified within the framework Mont theory As some researchers have suggested.

At the heart of the halo of the dark matter containing the spiral galaxies is a zone of uniformly high density, the size of which increases over time until it fills the spiral galaxy itself.

Thus, according to the researchers, a interaction that forces the theme of the halo to concentrate, just as the theme has a mysterious additional connection with the ordinary object, increases, but decreases, the size of this homogeneous core. Density over time.

At this time, it does not fit with the basic assumptions of the standard cosmological model, so it provides information on new constraints and the nature of the dark matter, the exact meaning of which must be explored.
