Physicist Stephen William Hawking proposed the black hole information paradox in the 1970s. He pointed out that after a black hole disappears, it will permanently lose its physical information, but this goes against quantum theory, which claims that any Messages never disappear. The latest research “hair theory” resolves the contradiction between the two concepts.
According to a study published in Physical Review Letters, by observing the properties of the black hole’s exterior, information about the matter inside the black hole can be inferred. The study, named “Hair Theory”, was developed from the “No-hair Theory”. The “hairless theory” points out that from the external characteristics of a black hole, only its mass, charge and angular momentum can be known, but the latest research calculates that more information can be inferred through the external characteristics of a black hole.
The researchers found that once matter falls into a black hole, it will leave a special mark in the black hole’s gravitational field, so that information about the matter can be observed. Scientists believe that the significance of this research lies in linking quantum mechanics and gravity and resolving the contradiction between the two.
One of the lead researchers, Xavier Calmet of the University of Sussex in the UK, said the study showed that the calculations of the two theories about black holes are consistent and can explain the storage of information, while There is no need to come up with new theories, though he admits that it will take time for the scientific community to adapt to the research.
