Do not panic.

Yes, astronomers think it's very likely that a "hurricane of dark matter" will invade the Earth as it races through the Milky Way ̵

1; but it should not cause any damage. In hunting for the mysterious particles (or particles) that make up dark matter, the "hurricane" may be our best chance for discovery.

Throughout the Milky Way, there are a number of star streams, accumulations of stars these were once dwarf galaxies or clusters. In antiquity, they collided with the Milky Way and were torn apart – leaving a beam of orbiting stars orbiting the galactic center. One such star stream, called S1, discovered last year by scientists who studied data from the Gaia European Space Agency (ESA) satellite, directly traverses the path of our Sun flies through dark matter at about 230 km per second (about 143 miles per second). A study published November 7, led by researchers from the University of Zaragoza, suggests that the dark matter present in the creek may fly twice as fast – about 500 km / s (about 310 miles per second) – what we have a much better chance of discovering dark matter.

Of course, we are not quite sure what dark matter is, but there are a number of candidates, including weakly interacting massive particles (WIMPs), gravitationally interacting massive particles (GIMPs), and axions – hypothetical elementary particles set by physicists ,

As the S1 star current flows directly through the solar system, the swirls of dark matter are likely to cross the path of various detectors located around the world to detect hypothetical particles. The study acknowledges that current iterations of WIMP detectors will likely not see dark matter from the S1 current. However, these are designed to detect "axionic dark matter" based on a hypothetical particle known as axion.

Since, in theory, dark matter consists of 85% of the matter of the universe, the detection of particles or particles is possible. That would fundamentally change how we look at the universe. So there is no need to worry if you hear the term "dark matter hurricanes" – it is indeed a good thing.
