    I'd not heard about Firewalls before reading this article, obviously I've not been keeping up-to-date with current theory.

    Hawking is famous for making discoveries and ideas without any calculations because he uses an imagination visual method of thinking about physics and mathematics unique to some people. He has made discoveries before and then went back and a year later proved them properly. I just hope he lives long enough to prove this one.

    [1401.5761] Information Preservation and Weather Forecasting for Black Holes

    Interesting. The upshot of this "train of thought" ( it isn't actually a fully developed paper as such ) seems to be that event horizons are only apparent, and that black holes are merely bound states of the gravitational field, and that the gravitational collapse is a chaotic process. Without the necessary maths, the details of his idea will remain somewhat elusive, though.

    is this similar to the "fuzzball" theory of blackholes?

    Sometimes it is better not knowing than having an answer that may be wrong.

    The Fuzzball model would immediately remove the need to hypothesise a firewall, since outgoing Hawking radiation would remain entangled with the internal states of the BH. Hawking, in his new paper, is trying to go into another direction by removing the event horizon itself; it remains to be seen if there is any merit to his idea or not. Personally, I am sceptical, but open to the results of further research on the matter.

    A handy set of articles from New Scientist to set the context:
    Hawking timeline: A brief history of black holes - space - 28 January 2014 - New Scientist

    And thank goodness they have changed their commenting policy (to: no comments allowed).

    But he's also had ideas and then went on to prove them invalid. Case in point: Primordial Quantum Black holes. His original thoughts were that during the early stages of the universe conditions could arise that would form low mass black holes, and that remnants of those holes should still exist to this day. However, he later unveiled Hawking radiation, which meant that such low mass black holes, even if formed would quickly evaporate, and thus would not last to our present time.

    A good article here which provides some background and then points out that there are a other explanations of the firewall paradox (but, as he says, these do not have such famous names attached).

    Yes, Virginia, Black Holes Exist!

    He who thinks to argue with Hawking is not thinking. The scientific method will prevail. Sifting through the links of this issue is a issue in it's self.. Time and study will reveal more of this yet open subject.

    “The absence of event horizons mean that there are no black holes – in the sense of regimes from which light can’t escape to infinity.” Most news sources seem to be ignoring the qualifier at the end.

    Two physics blogs I follow (BackReaction and Of Particular Significance) had posts on this topic recently:

    Sabine Hossenfelder - If it quacks like a black hole

    Matt Strassler - Did Hawking Say “There Are No Black Holes”?
