According to the theory of the famous physicist Stephen Hawking, black holes emit a slow burst of heat, known as a “superheat.” ‘Hawking radiation’, but because it is convective. Radiation therefore cannot transmit information. That means the process has destroyed all data. This includes information that it was once a star.
Yet the laws of quantum mechanics clearly state that any information in the universe cannot be destroyed. It became a problem between ‘classical physics’ and ‘quantum physics’ that have plagued cosmologists for decades. This is known as the ‘Hawking information paradox.’
However, a report published in the journal Physics Letters B. by Xavier Calmet, professor of physics at the University of Sussex, and colleagues suggests that ‘Hawking radiation’ is not radiation that radiates heat. And it can reveal the life span of a star before turning into a black hole. But it is not yet possible to generate that information with current knowledge and technology.
“Quantum physics doesn’t allow information to be destroyed. which means ‘Pre-black hole life’ could be reversed,” Calmet said. We should be able to reconstruct the original black hole. and finally recreate the story of Dao.”
However, the research team proposes what is known as ‘Quantum hair’ (Quantum hair) since 2022, which is a faint trace. that black holes leave behind in the gravitational field. they said When matter collapses into a black hole, it ‘leaves an imprint’ and that trace is healing. This is something Hawking didn’t do when he was thinking about the black hole problem.
“While these quantum gravitational corrections seem trivial, But they are important for black hole evaporation,” Calmet said. “We were able to show that these effects are not thermal radiation. in other words It’s factoring in quantum gravity, so this radiation can carry information.”
But for now these concepts are just The abstract ‘mathematical data’ exists. Data extraction by third parties via Hawking radiation is not possible. Because it requires a very sensitive instrument. and very small
But simulating it on paper has shown it to be possible, just as when Einstein discovered his black hole on a notebook. And scientists later observed it. This mathematical data is always very valuable.
