    Black Holes May Not Have 'Event Horizons' After All

    Information Preservation and Weather Forecasting for Black Holes
    http://arxiv.org/abs/1401.5761
    It has been suggested [1] that the resolution of the information paradox for evaporating black holes is that the holes are surrounded by firewalls, bolts of outgoing radiation that would destroy any infalling observer. Such firewalls would break the CPT invariance of quantum gravity and seem to be ruled out on other grounds. A different resolution of the paradox is proposed, namely that gravitational collapse produces apparent horizons but no event horizons behind which information is lost. This proposal is supported by ADS-CFT and is the only resolution of the paradox compatible with CPT. The collapse to form a black hole will in general be chaotic and the dual CFT on the boundary of ADS will be turbulent. Thus, like weather forecasting on Earth, information will effectively be lost, although there would be no loss of unitarity.

      "This suggests that black holes should be redefined as metastable bound
      states of the gravitational field."

      What he's proposing is pretty ballsy; basically implying that information can be retrieved from black holes, although it will be pretty fubar information to the point of being unrecognizable. It's been widely assumed for decades that information is totally lost once it passes the event horizon of a black hole though.

          ...even for Stephen Hawking isn't this is a bit of a stretch?

          will read later, definitely interesting.

              I've heard some things about black holes recently, the topic seems to be popping up recently so I'll give this a read later since it's captured my interest :P I know of someone that knows someone who's doing research on black holes by studying them as these pseudo-metric spaces where you throw away the axiom of nonnegative distance...cool stuff.
