Do not panic.
Yes, astronomers recommend that it’s highly likely that a “dark matter cyclone” will knock into the Earth as it speeds through the Galaxy– however it should not trigger any damage. In truth, in the hunt for the strange particle (or particles) that comprises dark matter, the “cyclone” might supply our finest possibility at detection.
Throughout the Galaxy there are a variety of excellent streams, events of stars that were as soon as dwarf galaxies or clusters. In ancient history they hit the Galaxy and were torn apart– leaving a stream of orbiting stars that circle the stellar centre. One such excellent stream, called S1 and found in 2015 by researchers taking a look at information from the European Area Firm’s Gaia satellite, passes straight through the course of our sun.
As our planetary system speeds through the external reaches of the Galaxy, it flies through dark matter at around 230 kilometres per 2nd (around 143 miles per second). A research study, released Nov. 7 and led by scientists at the University of Zaragoza, recommends that the dark matter present in the stream might be taking a trip at double that speed– approximately 500 km/s (around 310 miles per second)– providing us a better possibility at identifying dark matter.
Naturally, we’re not rather sure what comprises dark matter, however there are a variety of prospects consisting of weakly-interacting enormous particles (Pansies), gravitationally-interacting enormous particles (GIMPs) and axions– theoretical primary particles presumed by physicists.
Due to the fact that the S1 steller stream takes a trip straight through the planetary system, the dark matter cyclone is most likely to cross the course of numerous detectors spread out around the world established to spot these theoretical particles. The research study yields that present versions of SISSY detectors will likely not see dark matter from the S1 stream. Nevertheless, those are tailored to spot “axionic dark matter”, based upon a theoretical particle called an axion.
As dark matter is thought to comprise around 85 percent of the matter in deep space, detection of the particle or particles that make it up would essentially alter how we take a look at deep space. So, actually, there’s no cause for issue when you hear the term “dark matter cyclone”– in truth, its a good idea.
The only thing it’ll blow is your mind.
