consort to new inquiry , the universe could be a lot hairier than one might expect . The “ hairs ” are filum of dark matter which form as streams of gloomy subject pass near monolithic objective like planets or stars .
The existence of this fresh phenomenon was proposed by Gary Prézeau of NASA ’s Jet Propulsion Laboratory in apaperwhich will be print in theAstrophysical Journal . His simulation shows that the Earth should be surrounded by these filaments , with a bulkier , denser part ( the “ root ” ) towards our planet ’s surface and a thin , less dense part ( the “ tip ” ) away from it . The root would be site 1 million km ( 620,000 geographical mile ) from Earth and the tip would extend to over 2 million klick ( 1.2 million Swedish mile ) .
The hair would basically be concentrations of dark matter drift in the middle of space , shaped by the influence of the planets and the Sun . Interestingly , if they do exist – which is very much hypothetical at the moment – they could be explored and study by ballistic capsule in the futurity .
" If we could pinpoint the location of the root of these hair , we could potentially send off a investigation there and get a bonanza of information about dark thing , " Prézeau said in astatement .
Dark matteris a hypothetical kind of topic , accounting for about 85 percent of all the matter in the universe . It does n’t interact with electromagnetic radiation ( i.e. igniter ) so it can not be see , hence the appellative “ dark ” . It interacts only gravitationally , and its macrocosm was proposed to explain how all champion in a galaxy rotate around the centerfield at approximatelythe same speed .
We are yet to detect dark affair in the research laboratory , but computer simulation have tried to characterize and constrain its properties . It is thought that drab matter organise low - tightness steady streams locomote through galaxies . Thelow density of dark matter(about 10 - 22 kg m-3 ) makes it hard to notice it , but if the “ hair ” turns out to subsist , it would potentially give us an easy probability to observe it : The roots of disconsolate matter hair around our satellite are carry to be a billion times denser than the stream , although still more than a trillion fourth dimension less dense than air .
This pretence show another possible characteristic dark subject might possess , but as always , further studies are needed to affirm these findings and finally understand dark matter .
