The paper named Black Hole Entropy and Soft Hair, tackles with what happens to information when it falls into a black hole, a problem that theoretical physicists refer to as 'the information paradox,' said researchers from Cambridge University in the United Kingdom, as reported by The Guardian. The researchers, including co-author Malcolm Perry, reportedly completed the study days before Hawking's death in March.
Selling had contended that dark openings have a temperature. As such, black holes "must inevitably burn themselves out into nothing as they lose energy", explains the London Evening Standard. Quantum mechanics rules that information is never lost, but is encoded and conserved.
In the most recent paper, Hawking and his partners indicated how a portion of the data might be protected. I told him weâ€™d got somewhere.
The study was groundbreaking revealing that even Hawking's original argument was flawed in some way and most importantly that no-hair black hole theories were unfounded.
This is known as the black hole information paradox - and Stephen Hawking had been trying to crack it for decades. Stephen Hawking later updated the knowledge of black holes to include the fact that black holes have temperatures which cause them to evaporate from space.
The idea relies on entropy or the measure of internal disorder. "This paper summarizes the status of our long-term project on large diffeomorphisms, soft hair and the quantum structure of black holes until the end of our time together". "He knew the final result", said Perry.
"However, this does not resolve the paradox". These particles are said to be light to make it a sort of halo that is around the black hole which is called as soft hair in the paper. "It's telling you that soft hair really is doing the right stuff", Perry went on to say.
"The difficulty is that if you throw something into a black hole it looks like it disappears", Perry told the website.
It is not the end of the information paradox though.
"This is excellent progress, but we have much work yet to do", Strominger said.
And that's where this "soft hair" comes in, first proposed by Hawking in 2016: a way of explaining temperature and entropy shifts so that it fits with what we already know about how the Universe works.
