Want to find a back door to another Universe? Look for a black hole. According to a new radical theory proposed by Stephen Hawking, humans could escape from black holes, rather than getting stuck in them, or crushed to smithereens. Unfortunate those lucky space travelers won’t bragging about their close call on return to Earth, as they will end up in a different universe.
“The existence of alternative histories with black holes suggests this might be possible,” Hawking said, while speaking at Stockholm University. “The hole would need to be large and if it was rotating it might have a passage to 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. If you feel you are in a black hole, don’t give up,” he told the audience, with his classic sense of humor. “There’s a way out.”
A paradox has puzzled physicists for years is what happens to things when they go beyond the event horizon of a black hole, (in layman’s terms, “the point of no return”) where even light can’t get back. Scientists believe that the information about an object has to be preserved, even if the thing itself is swallowed up. Hawking suggests that the information is stored right on the boundary, exactly at the event horizon, which would mean that since it never makes its way into the black hole, it does not need to find its way out again either.
With this line of thinking humans might not disappear if they fall into a black hole. They’d either become a “hologram” on the edge, or fall out into another universe.
Well, even so, I think I’ll pass on that black hole trip.
