Hawking: Black holes aren’t so ‘black’ — they could lead us to other universes

Professor Stephen Hawking has outlined a new theory about black holes[黑洞], arguing they could lead to other universes. The astrophysicist[天体物理学家] said there was “a way out” of black holes, adding that he had discovered a mechanism[机制；原理，途径；进程；机械装置；技巧]“by which information is returned out of the black hole.” He said information lost in a black hole might be translated into a kind of hologram[全息图；全息摄影，全息照相] or break out into an alternative universe[平行宇宙 ；另类宇宙]. “The existence of alternative histories with black holes suggests this might be possible,” he said. “The hole would need to be large and if it was rotating, it might have a passage to another universe.”

The message of this lecture is that black holes ain’t as black as they are painted.

Astrophysicist Stephen Hawking

Hawking, 73, used a public lecture in Stockholm[斯德哥尔摩（瑞典首都）] to detail his thoughts about where lost information ends up after being sucked into black holes, a place where gravity compresses matter to a density where the usual laws of physics[通常的物理定律] break down. He said: ”[Black holes] are not the eternal[永恒的；不朽的] prisons they were once thought. Things can get out of a black hole both on the outside and possibly come out in another universe. … But you couldn’t come back to our universe. So although I’m keen on space flight, I’m not going to try that.”
