Black holes are the most ominous predictions of Einstein's general theory of relativity: excessive concentration of matter or energy in one place will eventually cause space to collapse, swallowing everything like a magician's coat, and everything can't escape. Until Hawking 40 years ago, Hawking The Ph. D. claims to subvert a black hole-or perhaps to completely overthrow it. His equation says that black holes don't last forever. After a period of time, they will "bleed" and then explode into radiation and particles. But there is one obstacle: according to Hawking It is estimated that the radiation emitted when the black hole collapses is random, and most of the "information" of everything falling into it will be erased. This violates a principle of modern physics: time can be reversed, and black holes occur Passed things can be rebuilt. The gist of this text is:. ['Hawking found a clue to escape the black hole.', 'Black holes will eventually "leak" and then explode into radiation and particles.', "Hawking's findings completely overturn predictions about black holes.", "Hawking breaks the black hole's perpetual prediction but presents new challenges."]
