scientist remember there ’s a " glum matter hurricane " heading toward Earth . In fact , it might even be blowing through us already .
But do n’t worry — it ’s definitely not going to down you . Mostly , it ’s just a bunch of normal sinister matter with especially honorable branding . And it really is headed ( more or less ) this direction .
Here ’s what ’s going on : Back in 2017,astronomers spotteda stretched - out parentage of stars passing through oursolar organization ’s oecumenical region of theMilky Way . The scientist mention this group the " S1 stream , " identifying it as the nigh of several prima stream moving through the extragalactic nebula . Parades of stars like these form when the Milky Way bolt up a nanus galaxy , stretching the smaller objective out in the unconscious process . In a young paper , put out Nov. 7 in the journal Physical Review D , researchers reason that S1 might be carry with it a brawny cargo of dark matter from the original dwarf galaxy . And they gave that baggage the snazzy name " glum issue hurricane . " [ The 7 Strangest Asteroids : Weird Space Rocks in Our Solar System ]
Again , that hurricane is not belong to shoot down you . Or gasconade the threshold off your family . But it just may cause some local spikes in sour matter , which would aid researcher hunting dark matter actually find the stuff , the researchers wrote .
That ’s because all galaxies , but especially dwarf extragalactic nebula , are held together by dark matter , physicists believe . So , the galaxy that was deplume to smidgeon birth the S1 stream likely dumped a bunch of dark thing into the stream ’s way .
The problem is , no existing dark subject - detection deviceshave actually worked , in part because they ’ve all been plan based on educated guesses as to what sinister topic really is . ( Scientists havevery salutary reasonto believe dark matter exists but are still estimate about its composition . )
So , the physicist behind the recent newspaper figure how dense S1 ’s dark matter would have to be to mold signals at several presently - to - be - built dark matter detector . When those detectors occur online , scientist will love a lot more about the " hurricane " and whether it ’s really spoil through our stellar neighborhood .
Until then , it ’s fun to reckon about , is n’t it ? A dense cloud of colored matter from a beat beetleweed blasting invisibly through us as it follow the stay stars on their unredeemed parade .
Whoooooooooooooooooooooooooooooooooooooooooooooosh !
