black holes - Does Stephen Hawking believe that General Relativity is wrong?



Stephen Hawking recently said that black holes do not exist. According to Wikipedia, black holes are predicted by General Relativity. So it would seem to follow that Stephen Hawking believes that General Relativity is wrong.


Am I missing something?



Answer



No, he does not think that GR is wrong. Actually, in his article on arxiv, he gives some ideas in order to (try to) solve a problem associated to the information paradox for evaporating black holes. That would mean that the usual idea of black hole we have would not longer be accurate. It does not imply that GR is wrong (at least on the domain of validity where we believe it provides a pretty good description of physics).
