Do not be afraid of dark matter Hurricane (dark matter Hurricane good)

Scientists think there is a "dark hurricane material" in the direction of Earth. In fact, it could even blow us up already.

But do not worry – it's definitely not going to kill you. Mostly, it's just a bunch of ordinary dark matter with especially good branding. And it really goes (more or less) this way.

Here's what happens: Back in 2017, astronomers noticed a tense line of stars passing through the general area of ​​our solar system and the Milky Way. The scientists called this group the "S1 stream," and identified it as the nearest star closest to the galaxy. Parades of such stars, as the Milky Way engulfs a dwarf galaxy, stretches the smaller object in the process. In a new article, published Nov. 7 in Physical Review D, the researchers argued that S1 may carry a heavy load of dark matter from the original dwarf galaxy. And they gave this charge the stormy 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 up the door from your house. But it may only cause some local spikes in dark matter, which will help dark matter hunt researchers actually find the material, the researchers wrote.

This is because all galaxies, but mostly dwarf galaxies, are held together by dark matter, physicists believe. Thus, the galaxy, which was torn to shreds that were born in the S1, apparently threw a bunch of dark matter into the stream.

The problem is that there are no existing devices for identifying dark matter, in part because they are all designed based on educated guesses about what really dark matter is. (Scientists have good reason to believe that dark matter exists, but still guess their composition).

Therefore, the physicists behind the last paper calculated how dark the S1 material would have to affect signals in some dark matter detectors that would soon be built. When these detectors are online, scientists will know much more about the "hurricane" and if it really blows through our stellar neighborhood.

Until then, it's fun to think about it, right? A thick cloud of dark matter from a dead galaxy bursts our way through our path as he follows the remaining stars on their lost march.
