In the Network appeared the last work of Stephen Hawking

Black holes, it turns out, had "soft hair", a sheen of photons surrounding the hole's event horizon where light can no longer escape its gravitational pull.

Now, colleagues at the universities of Harvard and Cambridge have published the very last paper that lists Hawking as an author, which builds upon the physicist's lifelong work on these enigmatic cosmic objects. A continuation of his groundbreaking research on black holes and Hawking radiation, the new scientific paper illustrates that some of the information engulfed by black holes can be preserved. But there is one condition, if black holes have the property "limited lifecycle" and may disappear with time.

Stephen Hawking, who died earlier this year, is one of the most-respected names in modern physics. Theoretical physicists commonly refer to this as the information paradox. The English scientist was interred in Cambridge.

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. It is basic physics that tells us that no information can ever be lost.

Any object that has a temperature also has an entropy', Professor Perry wrote in an article in the Guardian.

The late physicist's final paper on black holes and the information paradox has been revealed by his colleagues. "This work summarizes the status of our long-term project of large diffeomorphisms, "soft hair" and the quantum structure of black holes", - said in the Preface, the co-authors Sasha Jaco, Malcolm Perry and Andrew Strominger.

But if everything gets sucked into a black hole, never to return, what happens to the information that these objects used to hold? "It's telling you that soft hair really is doing the right stuff", Perry went on to say. So it turned out that black holes aren't entirely "black" - they emit "Hawking radiation", consisting of photons, neutrinos, and to a lesser extent all sorts of massive particles. Perry emphasised that this "is definitely not the entire answer" but there are "slightly fewer puzzles than we had before".

He said, "It was very hard for Stephen to communicate and I was put on a loudspeaker to explain where we had got to".

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. When I explained it, he simply produced an enormous smile. I told him we’d got somewhere. "He knew the final result", said Perry.
