The paradox of information stems from Hawking's theoretical argument in the 1970s that black holes have a temperature. As such, they will inevitably evaporate over time until there is nothing left, releasing energy that is now called the "radiation of Hawking ". You see, it is thought that when an object enters a black hole, its information is kept on the surface forever, even if it disappears from view. If a black hole evaporates, this information will also evaporate. This creates a paradox because according to the rules of quantum physics, information can never be destroyed.
The new document shows how this information can be preserved by photons called "fluffy hair" surrounding the edge of the black hole, which you could call the event horizon. According to Hawking, Perry, Andrew Strominger and Sasha Haco, the temperature of a black hole changes when you throw in an object (for example, the atoms of a planet). The hotter it gets, the more its entropy (its internal disorder) increases. This entropy is what is preserved in the soft hair of a black hole.
Perry said he had telephoned Hawking a few days before his death to discuss their work. "It was very difficult for Stephen to communicate and I was put on a speaker to explain where we were headed in. When I explained it, he simply made a huge smile. I told him we had gone somewhere, he knew the end result., "He said The Guardian. Scientists admit that there is still much to be done: "It's a step forward, but it's certainly not the solution," Perry said. "We have a little less headache than before, but there are definitely some troubling issues."
You can read the entire document in its pre-published state. Earlier this year, Hawking's latest article on multiverse theory was also published in the Journal of High Energy Physics, in case it suits you better.
