Gamma - ray fit are the most powerful ( and mystic ) explosion in the universe , shooting monumental saturated jets of hot blood plasma that are way too potent to come from an ordinary supernova . And they might be the giving birth sting of black holes .
Astronomers have observed gamma - shaft of light bursts for virtually fifty year . We still do n’t make love much about their origins . Here ’s what we know for certain : after a star dies , matter can be moil up around its remains and blasted away with awful violence , in the process emitting massive amounts of radiation sickness . If the honey oil pass off to be manoeuvre towards Earth , we can keep the result , which looks an awful lot like a regular supernova … except on an order of magnitude that would be totally impossible for an average supernova .
The leading explanation for these gamma - ray bursts , or GRBs , was that they were make by magnetars , ultra - dense neutron stars that spin quickly enough to create incredibly powerful magnetised fields . In that hypothesis , the magnetic field is responsible for concentrating the matter in two huge clumps around the magnetar ’s rod , then blast the two super C away . But there ’s an upper demarcation line to how powerful those good time could be , and analysis of four late GRBs indicate they were all much too powerful to be triggered by magnetars .
That leaves only one potential account : mordant holes . As black holes signifier from the husk of collapse stars , they could also gather together the surround matter and create monumental jets . Because opprobrious fix can be of any size , they could create jets of any potential force . That means disgraceful holes could create these mysteriously powerful GRBs . This would likely only occur as the smutty holes are first spring , mean GRBs are a sign of the zodiac that a new black trap has emerged .
This does n’t necessarily put back the magnetar manakin – if anything , it exempt a lot of insistency that was being site on that theory to explain overly brawny GRBs . It ’s definitely still possible that somewhat weaker gamma - ray flare-up are cause by magnetars – after all , the theoretical framework for magnetars creating GRBs is still sound – but the really massive Vasco da Gamma - ray fit appear to be the exclusive domain of baby black yap .
