Breaking news! The Earth is going through a hurricane of dark matter. Here are all the explanations

An unexpected announcement from scientists! A very rare phenomenon can be detected probably for the first time. They claim that a kind of "hurricane" of dark matter could make its way past the Sun, so it can be detected even from our planet, Earth.
The study, which was also published in Physical Review D, is led by Ciaran O'Hare from the University of Zaragoza in Spain.
About the study:
Scientist Ciaran began his studies by observing a line of nearby stars moving in the same direction, as it is known in science, stream S1. (stars moving in the same direction/stream S1: due to their motion and after several years of research it is believed that they are the remnants of a possible dwarf galaxy that was swallowed by the Milky Way several billion years ago, maybe even before Earth).
Indeed, the number of stars in our "proximity" is a huge one, the S1 stream having over 30,000 stars in different stages of life.
After all, what effect does this have on the dark matter coming to us?
First of all, there would be no problem with this stream, if it was "normal". This stream is one of the 30 known streams in our galaxy, all due to an internal collision, but the S1 stream is more special than others.
First of all, the stream blows past us with an impressive speed of approx. 310 miles (500 km) per second. Due to its speed and, above all, its existence, it can cause effects on the dark matter that is near us.
"Current detectors looking for weakly interacting massive particles (WIMPs) - one widely discussed form of dark matter - probably won't see any effect from S1, but future WIMP detectors might." said the researchers.
To give you an idea of what this stream brings, scientists say that about 10 billion solar masses of dark matter in the remnants of dwarf galaxies travel along this stream.
There is no evidence that this possible stream affects the Earth or life on Earth in any way, but mainly, nothing should happen. Especially since most likely, the stream passes right now.
At this time, perhaps for the first time, scientists will be able to make a direct detection of the dark meter (not done so far).
