We can not see or feel this hurricane, but knowing this may mean that the dark matter is discovered more easily than it was supposed to be.
The dark matter is one of the greatest secrets of the universe. Scientists have not yet discovered it directly. We do not even know exactly what it is – we know just so much that it exists. Proof of its existence is the movement of galaxies and stars: if the galaxies are weighed only to the extent that they can only be calculated with the apparent mass accumulation, then all of the stars at the edge of the galaxy emerge outside the intergalactic space due to the tremendous velocity.
Thus, the galaxy has something invisible – one that creates a mass and gravity with stars that are "tied" to their galaxies. Even considering the character of a star, we can calculate the missing, invisible mass. "The dark question," no matter what it is, is the name we gave to the missing mass, and physicists and astronomers around the world are sweeping through trying to capture the material that supplies this mass directly.
But so far this has not happened yet. How can physicists know that there is a huge dark storm? Or one of the stellar moves.
Astronomers have learned that many years ago Galactic Milky Way was swallowing a large spheroidal dwarf galaxy, but this event did not go unnoticed – it flew in the galaxy to free its mass flow, last year with the public release of Gaia satellite, which formed the galactic star.

And while Birdwatch does not have one such mass flow, S1, as it was called this particular phenomenon, is unusual, as the solar system falls on this 30,000-star trajectory.
Indeed, do not be afraid of the apocalypse, no stars will match. Do not hurt our planet and mass hurricane.
The theorist of the University of Zaragoza, Ciaran O'Hare, led a team of researchers who explained the impact of S1 on the dark matter in our galactic corner.
They analyzed various types of dark matter material density and propagation patterns in the stream of S1 and, based on the data obtained, the predicted dark matter that could be detected by sensors on Earth.
One of such potential elements is the hypothetical weak interacting mass particles, also known as WIMP. If these particles really exist, we should be able to detect them by decomposing electrons and atomic nuclei, and as a result, particles of Earth loaded can slide and isolate the light that liquid crystal or crystalline sensors may perceive.
According to their calculations, researchers have found that it is unlikely that WIMP sensors will perceive any S1 effect, although it is possible that technology could be improved in the future.
Axial sensors – for example, the Axonic dark matter experiment – can produce a more favorable result, although Axions is still only theoretically thought-out but experimentally undetectable particles. But if they really exist, then it's incredibly easy – about 500 million. Larger particles are lighter in electrons and they are probably the main component of a cold dark matter.
Physics Pierre Sikivie's calculations show that these particularly light particles that we do not see in a strong magnetic field can turn into photons that we can see.
"Axonic haloscopes have the highest potential sensitivity for the S1 flow when their dark matter component is sufficiently cold. As soon as the axial mass is detected, the axle power spectrum will allow you to easily deduct the S1 speed distribution," writes researchers at Saragossa University in his study.
In fact, so far this detector does not appear in the detection of a dark sign.
Researchers have published their findings in Physical Review D.
