Stephen Hawking says he may have solved a trouble that has plagued astrophysics for 40 years : the information lossparadox .
For decennary , scientist have argued about what come about to the information associate to the last of a star that forms a black hollow . It ’s known that nothing , not even light , can hightail it from a black hole owe to its vivid gravitational pull . Quantum mechanics , though , says that information can not be destroy ; general relativity says it must be . Hence , the selective information red ink paradox .
In the 1970s , Hawking said black holes could let loose “ entropy - less photons ” via quantum fluctuation – diminutive perturbations in space - time – calledHawking radiation sickness , but in 2004 he produced a raw possibility that claimed data could actually fly the coop from a blackened hole . How that would pass off was n’t clear , but now he says he has an answer .
“ I nominate that the information is not stored in the interior of the calamitous golf hole as one might expect , but on its bound , the event horizon , ” he saidtodayat the KTH Royal Institute of Technology in Stockholm , Sweden . Specifically , he enunciate a “ super translation ” takes piazza , which is fundamentally a holograph of the entropy . It means that data can live on and scat from a black hole at the effect purview , the boundary at which nothing is said to be able to break free .
They key to this theory is hawk radiation . Hawking says it can “ pick up ” information and move it beyond the event horizon . But it ’s not all good news ; the information is essentially useless . “ The selective information about ingoing atom is returned , but in a disorderly and useless form , ” said Hawking . “ This fix the information paradox . For all practical aim , the information is lost . ”
The outcome horizon is the boundary beyond which nothing , not even light , can escape . NASA / JPL - Caltech .
Hawking work on the melodic theme with theoretic physicist Malcolm Perry from the University of Cambridge and Andrew Strominger from Harvard University . Together with a host of theoretic physicists in Stockholm , they will discuss the inquiry throughout this hebdomad before presenting their conclude thoughts this Saturday .
“ The subject matter of this lecture is that black holes ai n’t as black as they are painted , ” hawk saidyesterday . “ They are not the eternal prisons they were once thought . Things can get out of a black hole both on the outside and perchance number out in another universe . ”
He elaborated that , if a black mess was large enough and rotating , it could have a passage to a parallel universe . “ But you could n’t amount back to our population , ” he said . “ So although I ’m keen on space flight , I ’m not going to prove that . ”
