Stephen Hawking believes he knows how information escapes black holes

'... Basically, Hawking argues that the information about particles sucked into the hole sit on the surface of the event horizon as holograms (2D afterimages of a 3D object). "The idea is the super translations are a hologram of the ingoing particles," he told the crowd. "Thus they contain all the information that would otherwise be lost." What's more, that information can actually escape a black holes pull thanks to Hawking Radiation -- the concept that photons can sometimes be ejected from a black hole due to random quantum fluctuations.

These photons would carry the information off of the event horizon, however it wouldn't be of any use. "The information about ingoing particles is returned, but in a chaotic and useless form. This resolves the information paradox. For all practical purposes, the information is lost." Even if the information wasn't blasted into a parallel universe (which Hawking said is totally possible), it'd be like trying to read the data off a corrupted hard drive. Sure there's still "information" there, it's just not going to be of any use.
