Stephen Hawking's Black Hole Breakthrough

Why cosmologist believes its possible to escape a black hole.

— -- Here's a piece of good news for deep space voyagers.

"I propose that the information is stored not in the interior of the black hole as one might expect, but in its boundary, the event horizon," Hawking said, referring to the line beyond which theories suggest even light cannot escape.

Before entering the point of no return in the black hole, information is encoded in a two-dimensional hologram on the event horizon, he said. The stored information is then emitted in quantum fluctuations in "chaotic, useless form," Hawking said, noting that "for all practical purposes the information is lost."

Hawking also theorized black holes might also be passages to other universes -- but with a caveat. Anyone who enters one wouldn't be able to come back to our universe.

"So although I'm keen on space flight, I'm not going to try that," he joked.
