It involves the extreme denseness of black holes, these objects capable of warping time-space which form when big stars collapse within themselves or when two stars collide onto each other. But in the 1970s, Hawking proposed that black holes might have a temperature and could slowly leak out quantum particles. These hairs surround the event horizon of a black hole, but how would they work?
However, the rules of the quantum world dictate that information is never lost.
The final scientific paper written by beloved theoretical physicist Stephen Hawking has been published posthumously by colleagues from Cambridge and Harvard. Perry, unaware of how ill Hawking had become, reached out to tell him the news.
In the new paper, Hawking and his team found a mechanism - which relies on as-yet-unproven assumptions - for counting the amount of inormation that soft hairs can carry.
In the Preface to the work co-authors Sasha Jaco, Malcolm Perry and Andrew Strominger said: "We are deeply saddened by the loss of our dear friend and colleague of Stephen Hawking, whose contribution to the physics of black holes remained vividly stimulating to the very end".
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.
What happens to information when objects fall into black holes?
He said, "It was very hard for Stephen to communicate and I was put on a loudspeaker to explain where we had got to. He knew the final result", Perry told The Guardian. Eventually, black holes will evaporate, leaving a vacuum that is the same everywhere else.
"However, this does not resolve the paradox".
"We think it's a pretty good step, but there is a lot more work to be done". However, scientists are confident that they exist, judging from their theoretical calculations and observations of X-rays emitted by swirling disks of gas around the black hole.
