*Ø* Hawking resolves black hole dilemma

[Or does he?]

From the Irish Times:

"The information paradox on black holes was resolved by Prof Stephen Hawking when he rejected his earlier theory that they irretrievably swallow up everything, writes Daniel McConnell

"Internationally renowned scientist Prof Stephen Hawking announced in Dublin yesterday that he had solved one of the 'major problems in theoretical physics'.

"His new theory, however, which states that information can actually be recovered from black holes, is unlikely to end the long-standing debate within the science community that has been running for over 30 years ...

"Black holes were often thought of as being void areas of space into which energy and matter can fall and disappear forever. In 1974 Prof Hawking discovered that, in fact, they are not completely 'black' but that they emit radiation, now known as Hawking radiation. This discovery led to what has been known as the information paradox on black holes which has puzzled the international science community ever since ...

"Prof Hawking conceded that his previous theory that all information was lost was incorrect and the assembled crowd witnessed the conclusion of a long-standing bet between him, Prof Kip Thorne and Prof John Preskill."
