Stephen Hawking's last scientific paper - which was finished days before the British physicist's demise - has been composed and posted online by his partners at Cambridge and Harvard colleges.
The paper named Black Hole Entropy and Soft Hair, tackles with what happens to information when it falls into a blackhole, a problem that theoretical physicists refer to as "the information paradox", said researchers from Cambridge University in the United Kingdom.
The Guardian reported that the work tackles something that theoretical physicists are calling the information paradox and it was completed in the days before Hawking passed away.
The physicists show in their paper that a black hole's entropy may be recorded by photons that surround the black hole's event horizon, the point at which light can not escape the intense gravitational pull.
Among the unknowns that Perry and his colleagues must now explore are how information associated with entropy is physically stored in soft hair and how that information comes out of a black hole when it evaporates.
"It was very hard for Stephen to communicate and I was put on a loudspeaker to explain where we had got to". I told him weâ€™d got somewhere. These soft hair are low-energy quantum excitations that can release information when the celestial object evaporates. "He knew the final result", said Perry.
Any object that has a temperature also has an entropy', Professor Perry wrote in an article in the Guardian.
"A black hole's entropy - or internal disorder - can be recorded by these photons around the edge".
"What this paper does is show that "soft hair" can account for the entropy", said Perry. The difficulty is that if you throw something into a black hole it looks like it disappears. It's telling you that soft hair really is doing the right stuff'. Then, in 2016, Hawking, along with the co-authors of his latest study, said they may finally be on to something.
Hawking's research played a key role in our current understanding of black holes. "The authors have to make several non-trivial assumptions so the next steps will be to show that these assumptions are valid".
