Hawking backs down on black holes

 Stephen Hawking says he was wrong about a key argument he put forward 30
 years ago on the behaviour of black holes. 

 The world-famous physicist addresses an international conference on Wednesday
 to revise his claim that black holes destroy everything that falls into them 

 He will tell the Dublin meeting that he now believes black holes may after
 all allow information to get out. 

 Gary Gibbons, another physicist at Cambridge who attended the seminar, said
 Hawking's newly defined black holes did not have a well-delineated "event
 horizon" that hid everything in them from the outside world. 

 "It's possible that what he presented in the seminar is a solution," Professor
 Gibbons told New Scientist magazine. "But I think you have to say the jury is
 still out."
