Scientists believe that a "hurricane of dark matter" is heading for the Earth. In fact, it might even be crossing us.
But do not worry, it certainly will not kill you. Most of the time, it's just a bunch of normal dark matter with great branding. And that is really heading (more or less) in that direction.
Here's what happens: In 2017, astronomers spotted an elongated row of stars crossing the general area of the Milky Way of our solar system. Scientists have named this group "flux S1", identifying it as being the closest to several stellar flows moving in the galaxy. Streaks of stars like these are formed when the Milky Way engulfs a dwarf galaxy, thus stretching the smallest object. In a new article, published November 7 in the journal Physical Review D, the researchers claimed that S1 may carry a heavy load of dark matter from the original dwarf galaxy. And they gave this luggage the catchy name "hurricane of dark matter". [The 7 Strangest Asteroids: Weird Space Rocks in Our Solar System]
Again, this hurricane is not going to kill you. Or blow the door of your house. But this could simply cause local peaks in dark matter, which would help researchers in search of the material to find the material, he writes.
Indeed, all galaxies, especially dwarfs, are held together by dark matter, say physicists. . So, the galaxy that was torn by the birth of the S1 stream probably threw a bunch of dark matter on the way to the stream.
The problem is that no dark matter detection device has worked, in part because they were all designed on the basis of educated guesswork as to what is really dark matter. (Scientists have very good reasons to believe that dark matter exists but are still wondering about its composition.)
The physicists at the base of the recent paper have calculated how much the dark matter density of S1 should to be influential many times. Dark matter detectors built When these detectors come online, scientists will know more about the "cyclone" and about whether it really hits our stellar quarter.
Until then, it's fun to think, is not it?
Whooooooooooooooooooooooooooooooooooooooooooooo
