We just snappedour best photo yetof dark subject , but we still do n’t know just what it is . Now we might have a way to ( literally ) shed some light on disconsolate issue … with an assist from crack - monolithic black holes .

As affair falls into the tops - massive black holes at the center of many galaxies , huge super acid of molecule are shoot out of the black-market hole at close to the hurrying of light . ( The creation of these atom is a bit more complicated than that , but that will do for our purposes . ) These jets , which are a like a “ cosmic belching ” from the black hole , could clash with collections of coloured issue – and that , according to Stefano Profumo of UC Santa Cruz , is when things get interesting .
We still are n’t certain exactly what dark subject is ( although here’san excellent primeron what we do know ) , but one lead theory holds that dark matter corpuscle are thesupersymmetricpartners of the subatomic molecule that we ’re more conversant with and that make up the world of regular matter . Another suggests the dark matter partially exist in a fourth spacial attribute that we ca n’t see , an idea that is lent some support by current theoretic physics .

Either elbow room , Profumo say the effect of a collision between morose matter and negatron green from the bootleg fix would be moderately much identical . Unlike a lot of other possible collisions , in which the electrons would just rebound off the other particles , here they would in reality fuse with the toilsome dark issue particles . This would create a gloomy matter electron , which would either be a supersymmetric or excess - dimensional negatron , depending on which theory is right . The energy exchange call for in get this fresh corpuscle would be vivid , and most of the electron ’s energising energy would be sapped in the physical process . This would slow the newly created dark topic electrons to a virtual tie-up .
In all likelihood , the particles create would be mentally ill , and they would presently decompose back into dismal affair corpuscle and steady electrons . But this decay cognitive operation would cause the negatron to let loose da Gamma rays , which would then slowly fan out in all directions away from the ball of electrons and dark issue . Those gamma rays would be detectable from Earth , and they would be easily distinct from the tightly focused , fast - go jets of particles come from black holes .
Profumo and his team enounce they ’ve already found one galaxy that might be have this phenomenon . The distribution and frequency of gamma shaft of light emanating from the black trap at the plaza of the galaxy Centaurus A does n’t quite fit the orthodox predictions , and they believe this dark affair interaction core could account for the imbalance . Another galaxy they ’ve tested , Messier 87 , does n’t fit their predicted essence , but then it ’s potential that , for reason unknown , Centaurus A has a much gamey concentration of dark matter than Messier 87 .
