All is not lost if you fall into a black hole – you could simply pop up in another universe, according to Stephen Hawking.
The celebrated physicist has a new theory about where lost information ends up after being sucked into a black hole, a place where gravity compresses matter to a point where the usual laws of physics break down.
In a public lecture in Stockholm, Sweden, Prof Hawking said: “If you feel you are in a black hole, don’t give up. There’s a way out.” He said he had discovered a mechanism “by which information is returned out of the black hole”.
He was speaking at the KTH Royal Institute of Technology, which is hosting the Hawking Radiation Conference dedicated to examining the mystery of the “information paradox” – a conundrum concerning what happens to things swallowed by black holes.
Information about the physical state of something disappearing into a black hole appears to be completely lost. But according to the way the universe works, this should be impossible. Even information falling into a black hole ought to end up somewhere.
According to Hawking, it does – in one of two ways. Either it is translated into a kind of “hologram” on the edge of the black hole, or it breaks out into an alternative universe.
