摘要: 黑洞信息佯谬自提出至今已困扰理论物理学家近50年。揭秘黑洞信息佯谬是研究量子引力理论的一个重要途径。最近,物理学家在半经典引力理论下给出了黑洞蒸发过程的佩奇曲线,这表明在黑洞蒸发过程中确实释放了信息,从而证实无任何的信息丢失,这也宣告着黑洞信息问题的解决。文章以时间顺序来介绍黑洞信息佯谬研究的历史和现状。

Abstract: The black hole information paradox has bedeviled theoretical physicists for nearly 50 years since it was entranced. It is regarded as an important approach to study the theory of quantum gravity. The key to the question is whether the Page curve of the black hole evaporation process can be given. However, in the last year, the research of this problem was made a breakthrough. Physicists calculated the Page curve under the semiclassical theory of gravity, showing that information was indeed released during the evaporation of the black hole and no information was lost. This also announces the solution of the black hole information problem. This paper introduces the history and latest progress of the research on black hole information paradox in chronological order.
