We can not see or feel this hurricane, but knowing if it can mean that dark matter is detected more easily than you thought.
Dark matter is one of the world's biggest secrets. Researchers have not found it directly. We do not even know exactly what it is – we only know so much that it exists. Evidence of its existence is the movement of the galaxies and stars: if the galaxies are weighed only to the extent that they can only be calculated by accumulation of the mass of the apparent masses, all the stars on the galaxies will splinter over the intergalactic space because of the enormous movement velocity.
Thus there is something invisible in the galaxy – something that creates mass and gravity, which keeps the stars "tied" to their galaxies. Even according to the stars we can calculate the amount of missing, invisible mass. "Dark matter", whatever it is, is the name we gave to the missing mass, and physicists and astronomers around the world by trying to capture the material that supplies that mass directly.
But so far it has not yet happened. How can physicists know that a big storm of dark matter happens? Or from the same star movement.
Astronomers found out that many years ago the Galaxy struck a large spherical dwarf galaxy, but this event did not go without traces – it went through the galaxy to release its mass flow, last year with the release of the Gaia satellite, which formed the galactic star.

And while there is no such mass flow through Bird Tak, S1, as it is called this phenomenon, is unusual, because the solar system, like the 30,000 other stars, is surrounded by only the hurricanes of this mass.
True, do not be afraid of the apocalypse, no stars will collide. Do not hurt our planet and the mass hurricane.
Physics Theorist at Zaragoza University, Ciaran Hare, led a group of researchers who explained the impact of S1 on dark matter in our galactic corner.
They analyzed different density and distribution pattern for dark matter in the S1 current and, based on the data obtained, predicted dark matter that could be captured by sensors on the ground.
One of these potential features is the creation of hypothetical weakly interacting mass particles, also known as WIMPs. If these particles really exist, we could discover them through collisions with electrons and nuclear nuclei. Therefore, soil-loaded particles can creep and isolate the light that liquid crystals or crystalline sensors can capture.
According to their estimates, researchers have found that WIMP sensors are not likely to capture any S1 effect, but it is likely that in the future it would be possible to refine the technology.
Axial sensors – such as the Axonic Dark Matter Experiment – can provide more beneficial results, although Axions is still only theoretically thought-out but experimentally undetectable particles. But if they really exist, it's incredibly easy – about 500 million. Larger particles are easier for electrons and they are likely to be an important part of a cold dark matter.
Calculations of physicist Pierre Sikivie suggest that these ultra-light particles that we can not see in a strong magnetic field can be photons we can see.
"Axonic haloscopes have the highest possible sensitivity to S1 flow if their dark material component is cold enough. As soon as the axial mass is detected, the axle current spectrum will enable you to easily retract the S1 speed distribution," wrote a researcher at Saragossa University in his research paper .
Certainly, so far, the detector does not detect any dark signal detection.
Researchers have published their findings in the Physical Review D magazine.
