I recently read in the news that Stephen Hawking claims to have solved the Black Hole Information paradox. I researched a bit about the paradox and the research that Stephen Hawking did to solve it. However, I happened to stumble across several sites that claim that the paradox hasn't been solved yet. So which is true? And what exactly is the solution proposed?
The paradox is not solved yet because so far Hawking has only given a 1-page proposal (The Information Paradox for Black Holes ) on how to solve the problem. The details are still missing, but they will appear in a future work with M.J. Perry and A. Strominger.
Basically the proposal is that the information is conserved, because particles that fall into the black hole cause a supertraslation (a particular symmetry of the metric linked to the gravitational memory effect) that leaves an imprint on the outgoing (evaporating) particles.
