Black hole information is one of the greatest puzzles of theoretical physics from the 20th century that has persisted into the 21st century. After Stephen Hawking discovered black hole evaporation in 1974, in 1976 he predicted that black hole formation and evaporation would cause a pure quantum state to change into a mixed state, effectively losing information from the universe. In 1979 I questioned this conclusion, as many years later did many others, and in 2004 Hawking conceded that black hole evaporation does not lose information. However, a minority of gravitational theorists have not accepted Hawking's concession. There do remain many puzzles about black hole information, such as how it gets out (if it indeed does), and whether there are firewalls at the surfaces of old black holes that would immediately destroy anything falling in.
关于“墨子沙龙”
墨子沙龙是以中国先贤“墨子”命名的大型公益性科普论坛，由中国科学技术大学上海研究院主办，中国科大新创校友基金会、中国科学技术大学教育基金会、浦东新区科学技术协会、中国科学技术协会及浦东新区科技和经济委员会等协办。
墨子是我国古代著名的思想家、科学家，其思想和成就是我国早期科学萌芽的体现，“墨子沙龙”的建立，旨在传承、发扬科学传统，建设崇尚科学的社会氛围，提升公民科学素养，倡导、弘扬科学精神。科普对象为热爱科学、有探索精神和好奇心的普通公众，我们希望能让具有中学同等学力及以上的公众了解、欣赏到当下全球最尖端的科学进展、科学思想。
