The scientist Stephen Hawking has raised during his appearance at the Hawking Radiation organized by the KTH Royal Institute of Technology of Sweden, which brings together the 32 most important physicists in the world , that he may have solved the paradox of the loss of information related to black holes, an unsolved enigma – until now – for almost half a century.
What happens to the information related to the death of a star that ends up forming a black hole? According to quantum mechanics, information cannot be destroyed. According to general relativity, quantum information must be destroyed no matter what happens. Here is the paradox of information loss in black holes.
Hawking’s answer is simple: “ I propose that information is not stored inside the black hole as expected, but at its limits, in the event horizon , from where information can escape. Black holes are not as black as they are painted. They are not prisons as was eternally believed. Things can go out of a black hole and possibly do so in another universe. But you can’t go back to our universe. So even though I’m interested in space flight, I’m not going to try it, ”explained Hawking.
This means that the black holes would not swallow or destroy the physical information but would store it in a two-dimensional hologram fixed at their edges and representing their point of no return. The information would be stored in the form of so-called super translations .
“The idea is that the super translations are a hologram of the incoming particles. So they contain all the information that would otherwise be lost. This information is emitted in the quantum fluctuations that black holes produce, albeit in a chaotic , useless way. For all practical purposes, information is lost, ”says Hawking.
