Scientists believe that there is a “dark matter hurricane” heading toward Earth. Moreover, he is able even now to move through our territory. However, there is no reason to worry, because this is not a deadly event. In fact, this is only a cluster of dark matter with an unusual design.
What is going on? Back in 2017, astronomers discovered a stretched line of stars passing through the area of the Milky Way, where the solar system is located. The researchers called this group “S1 stream”, identifying it as the nearest stellar stream moving through the galaxy. Star parades appear when the Milky Way absorbs a dwarf galaxy and stretches it.
In a new study, scientists believe that the flow of S1 is able to carry with it a huge appendage in the form of dark matter from the original dwarf galaxy. Agree, the name “dark matter hurricane” suggests not the most pleasant associations, but there is nothing to be afraid of. This hurricane will not harm us and will not tear down the roofs of our houses. However, he is able to bring behind him local bursts in dark matter, which will help the dark matter hunters to possibly detect this mysterious substance. Physicists believe that all galaxies (especially dwarf ones) are held together by dark matter. Therefore, a torn galaxy that produced the flow of S1 left a large amount of dark matter running along with the flow. However, there is a problem. Humanity does not have the necessary devices for detecting dark matter, because all of them are created on the basis of conjectures and assumptions about the mysterious substance, and not real experiments.
Scientists have managed to derive calculations that show how strongly dense dark matter in S1 should affect the signals in some detectors. The information obtained will allow us to learn more about the hurricane and note its presence in our star area. In the meantime, let's just present this picture. A dense cloud of dark matter from a dead galaxy bursts through our territory, following surviving stars doomed to wander forever in a cold space.
