Black holes are the most ominous predictions of Einstein's general relativity: too much matter or energy concentrated in one place will eventually lead to the collapse of space, swallowing everything like a magician's coat, and everything cannot escape. It wasn't until 40 years ago that Dr Hawking claimed to have subverted the black hole-or perhaps completely. His equation shows that black holes do not last forever. After a period of time, they leak and then explode into radiation and particles. However, there is an obstacle: according to Hawking's estimate, the radiation emitted by the collapse of a black hole is random, and most of the information of everything that falls into it will be erased. This violates a principle of modern physics: time can be reversed and what happened in a black hole can be rebuilt.
