    The article is nice but makes an error. It uses "singularity" when it should use "event horizon". Singularities are mathematical indications that your physical theory is no longer any good. They are not physical. A BH's math model singularity is always hidden behind the event horizon.

    Hopefully in a few months more we'll have the interferometric imaging of Sgr A* released..... Then we'll have a picture and won't need to guess.

    The artists' impressions in the article don't account for optical distortion due to the BH's gravity field. There was a movie recently (sorry, forget the title) that attempted to portray the distortion with an accurate visual presentation, using ray tracing that simulated the spatial distortion.

    watched a tv program on black holes was very very interesting as there was a sugestion from Pro. Hawkins that they may be furry or have attenna to hold / store information that in the event of a singularity would be lost ? - i think ive got that right , im sure ill be corrected, but as long as i aint on this sucker i dont care

    In the physical world there is no singularity to lose. It is expected that in a good quantum theory of gravity that there is no singularity. Hawking's speculation has holes in it since it is done without the benefit of quantum gravity.
