Has Stephen Hawking solved a big black hole mystery?

You could escape a black hole, Stephen Hawking says in a theory Gizmodo describes as “fantastically insane”.

The famous physicist believes you might end up in another universe through a mechanism “by which information is returned out of the black hole”.

Alternatively you might be trapped as a two-dimensional hologram at the edge of the black hole.

His theory is that after being sucked into a black hole lost information ends up in a place where gravity compresses matter to a point where the usual laws of physics break down.

“If you feel you are in a black hole, don’t give up. There’s a way out,” he told a crowd at a public lecture in Stockholm hosted by the KTH Royal Institute of Technology.

“The existence of alternative histories with black holes suggests this might be possible,” Hawking said.

“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.”
