We are fully entering a stream of dark matter or, as the researchers have called it, a hurricane, as published last week in the magazine Physical examination D. However, because of the little interaction supposed on dark matter, the most likely is that we do not realize what is happening. But for researchers This may mean solving one of the biggest unknowns of modern physics.

However, we do not take speed with respect to events because, to solve this mystery, it is likely that time is still necessary. How did we see this hurricane black matter? Where does it come from? What can this mean for scientists? Can we now detect dark matter?

We have to go back a year ago, when the Gaia probe He detected an abnormality in the Milky Way. They were Cianan O Hare, from the University of Zaragoza, and his colleagues who found with S1, "a flood of galactic material," as the researcher explained hypertext. It's "a material in our galaxy that travels all the way through a stream," he adds. And what are these currents? Well, "the smallest galaxy remains that has been meals for our galaxy. "

The peculiarity of this current is that, according to current theories, galaxies are surrounded by dark matter. This current "will also bring a large amount of dark matter to the solar system" and, moreover, its movement will be very fast. Although "We do not know how much" dark matter might haveresearchers are "waiting" for one of the current experiments to sound the alarm bell to finally find it. The speed of this current is 500 km / s compared to the 230 km / s we are used to, so it was cataloged as hurricane and that the chances of finding it increase.

Although anything can happen, the scientists in this study are betting that one of the experiments already under way, such as that of Underground Laboratory of Canfrac -in the Aragonese Pyrenees, under the Montaña del Tobazo-, give what you it takes years to search and finally answer one of the great unknowns of modern physics: is there dark matter?

However, "we all hope to detect some dark matter someday, but we still have no evidence of the particle it is, although we have several ideas," says O & # 39; Hare . "That's why We test all optionsAnd many experiences around the world are looking for it! ", Adds the researcher. WIMP (for its acronym in English) and axiones.

The first option is a massive particle of weak interaction, whose mass can oscillate between a few times and hundreds of times that of the proton and that, if it collides with other atoms, it could produce a nuclear interaction in any detector located on Earth. While axions, on the other hand, are very light and able to become photons if there is an intense magnetic field nearby. These particles are becoming the favorite particles of scientists to be dark matter.

"S1 helps us in the search for dark matter, because in some cases this the signal is stronger or easier to detect"explains O & # 39; Hara, this current could make the dark matter" stronger "and thus avoid the noise experiences that are made. In addition, this trend will also help us to "better understand life and History of our Milky Way"he concludes.
