Stephen Hawking published a new theory about the ability of black holes to store information, he proposed this theory last year, but his research newly disclosed now with his colleagues Malcolm Perry and Andrew Strominger before he died.
This paper attempts to solve the paradox of losing information in black holes (loss of paradoxical information). We know that no one can escape the black hole, even the light itself. Therefore, any information related to what has been swallowed black hole must be lost.
In any case, this poses a problem by proposing that all black holes are essentially identical, none of them containing what has happened throughout their history. To counter this, the scientists suggest the "hair" theory, which says that space-time waves and hair can store information on the event's horizon, the inner boundary of a black hole.
"This paper gives a direct picture of fine hair in terms of soft gravitons, or photons on the horizon of black holes," the paper said.
His hair is as follows: They are a single ray of light moving away from the black hole, but they become frozen on the event horizon, according to Michael Byrne of "Matterboard". They are distortions in spacetime in the form of "super transitions" that may contain information associated with black holes.
"This symmetry is the only thing we know about black holes," Strominger explained to the American Science Journal. "You can move regularly back and forth all the time along the rays of light." Strominger is one of the authors involved with Hawking in writing papers.
"But there is another analogy, something new in this paper (although much of it has been discussed elsewhere)," Strominger says, "it is the symmetry that drives individual light rays up and down." A single light ray cannot communicate with each other, I ride one of them, causality prevents you from talking to someone who rides a nearby light, so that these rays of light are not interconnected, and you can make them slide up and down for one to another.
Hawking and his collaborators are particularly interested in particles that have near-zero energy, known as soft particles, or soft hair in this case. These particles are located on the event horizon, so that when they are removed - through what is known as Hawking radiation - these particles can transmit this information along with it along the way in the universe.
When he presented his theory for the first time in August, Hawking said that the information capture was chaotic and useless. But that would solve the paradox of losing the information, which means the black holes are different from each other. This paper is now a theory, and the debate about the whereabouts of poetry or not has actually begun. Tanya Ulf Danielsson A physicist at the University of Osala in Sweden, told the American Journal of Science that same month: "Will it finish anything, or will it make us even more confused?
however, this paper is an interesting proposition that explains how black holes hold some information, perhaps another step toward solving one of the old paradoxes in particle physics.
