Stephen Hawking has bring out a fresh theory on how mordant hollow are able to lay in entropy . He proposed the theorylast yr , but now with fellow Malcolm Perry and Andrew Strominger he has unveil his research . A pre - mark is useable onarXiv .
The report attempts to solve the notable black golf hole " selective information loss"paradox . We have a go at it that nothing can escape from a dim hole , not even illume itself . Thus , any data on what a fatal golf hole has consumed should also be lost .
However , this poses somewhat of a trouble , as it suggests all ignominious pickle are basically selfsame ; none of them would contain information on what pass off in their history . So to counteract this , scientists had aim a “ whisker ” theory . This suggest that ripples in blank space - time , the so - called hairs , could store data at the event purview , the boundary to the inner black hole .
" This paper gives an expressed description of soft hair in terms of gentle gravitons or photons on the disastrous hole skyline , " the paper states .
The hairs work like this : They are single rays of luminance move by from the fateful golf hole , but they get " frozen " at the event horizon , explain Michael Byrne forMotherboard . They are deformities in space - time in the form of " super - translation " that could hold back information on the black hollow ’s yesteryear .
" There ’s this symmetry of a grim hole that we all knew about in which you move uniformly onward and backward in time along all of the low-cal rays , " excuse Strominger , one of Hawking ’s co - authors , in an consultation withScientific American .
" But there ’s another symmetry , which is the novel thing in this newspaper ( though various forms of it have been discussed elsewhere ) . It ’s a balance in which the private visible light rays are go up and down . See , single lightness ray ca n’t let the cat out of the bag to each other – if you ’re rag on a light beam , causality foreclose you from talk to somebody ride on an adjacent spark electron beam . So these light rays are not tether together . you may slew them up and down comparative to one another . That slew is called a superintendent - translation . "
vend first presented the theory in Stockholm , Sweden , in August 2015 . KTH
peddling and his colleagues are particularly interested in speck with passably much zero energy , cognise as “ soft ” particles , the indulgent whisker in this case . The particle lie at the effect skyline , so when other speck are discharge – know asHawking radiation – they can pick up this information on their way into the universe .
In August , though , when he first portray the possibility , Hawking said this blame up data was “ disorderly and useless . ” But it would conclude the info loss paradox , and stand for that black holes are dissimilar from each other .
The paper is very much just a theory for now , and the " fuzz vs no tomentum " debate has already begun . " Will this actually settle anything or just allow for us in an even gravid state of confusedness ? I ’m not really sure , " physicist Ulf Danielsson of Sweden ’s Uppsala University toldScientific Americanback in August .
even so , it is an interesting marriage offer that may excuse how calamitous holes can keep some information – and it could be a footmark towards solving one long - stand paradox in particle purgative .
