Interactions between dark matter and ordinary matter.

Because dark matter is called dark, it may hide some sinister secret or cosmic forces that scientists prefer to keep secret. Although these ideas are fascinating to conspiracy lovers, the truth is much simpler and still intriguing. The name dark matter comes from a fundamental characteristic that it does not interact with light. This means that dark matter is literally invisible to our eyes and to any instrument that depends on light to detect objects. Imagine a particle of light or photon traveling through space when it encounters a common object such as a planet or a star, it interacts with it by reflecting or being absorbed, but when that same particle encounters dark matter, nothing happens, it simply passes by, as if dark matter was not there, that is exactly why we cannot see it directly and its presence can only be perceived through its gravitational effects and here is the curious thing, dark matter has mass and as we know where there is mass there is gravity.

This means that, although we cannot see it, dark matter can attract and influence ordinary matter, however, until now gravity was the only force that we knew that made dark matter interact with the rest of the universe, but what if you I said that's starting to change. A new study is revealing something that could revolutionize our understanding of the Cosmos, scientists are discovering hints that dark matter and regular matter could interact in other ways besides gravity, if confirmed it could mean that current models of dark matter, those we use to understand the universe are wrong and this would clearly lead us to develop new tools to detect this Mysterious substance that makes up a large part of the universe.

By the way, did you know that dark matter represents approximately five times more mass in the universe than ordinary matter, without it entire galaxies simply would not hold together. It is the invisible presence of dark matter that explains phenomena such as the strange movement of some stars which seem to ignore the laws of physics that we know, for example, the rotation curves of Galaxies show that stars on the outer edges of spiral Galaxies move as fast as those closer to the center. This can only be explained by the presence of an invisible mass, dark matter, this new discovery could be the first step towards a new understanding of dark matter and who knows maybe also dark energy another great Mysterious force in the universe, but Like any great scientific discovery, there are still many unanswered questions; What caused this interaction? What type of force is acting between dark matter and ordinary matter? Scientists are still far from completely solving this mystery, but the fact that they have found this clue is already a historic milestone in the quest to understand the universe.
