    Article expansion[edit]

    This article should expand to emphasize that there is a wider range of aspects involved around description of what properties black holes poses - because definition of black hole in astronomy differs from definitions and proposed properties of black holes for purposes of mathematics, metaphysics, science-fiction (and pseudo-science in general) and psychology for example.— Preceding unsigned comment added by 109.93.211.157 (talkcontribs) 21:18, July 10, 2013 (UTC)

    Done? -- AstroU (talk) 02:22, 17 November 2014 (UTC)
    No, because 1) I cant make grammatical sense of the comment. 2) The part that I am able to parse is untrue. (Black holes in astronomy and mathematics have exactly the same properties (for as far as we know anyway.) TR 14:09, 17 November 2014 (UTC)

    Missing commata[edit]

    3rd paragraph, 2nd sentence: "After a black hole has formed [comma missing] it can continue to grow by absorbing mass from its surroundings." 149.172.54.252 23:20, 2014 October 18

    New NEWS today, for future editing[edit]

    A lot of news about Black Hole discovery possibilities.

    Headline-1: Black hole at Milky Way center may be emitting mysterious neutrinos, NASA says

    QUOTE: "The massive black hole at the heart of our milky galaxy may be churning out peculiar particles called neutrinos, NASA satellites have revealed. If verified, it would be the first time neutrinos have been traced to the darkest regions of spacetime. The subatomic activity was first detected by three NASA satellites, which observe in x-ray light: the Chandra X-ray Observatory, the Swift gamma-ray mission, and the Nuclear Spectroscopic Telescope Array (NuSTAR), [NASA said in a press announcement]." -- AstroU (talk) 02:28, 17 November 2014 (UTC) -- PS: FYI for future editing.

    Headline-2: NASA X-ray Telescopes Find Black Hole May Be a Neutrino Factory

    QUOTE: "The giant black hole at the center of the Milky Way may be producing mysterious particles called neutrinos. If confirmed, this would be the first time that scientists have traced neutrinos back to a black hole. The evidence for this came from three NASA satellites that observe in X-ray light: the Chandra X-ray Observatory, the Swift gamma-ray mission, and the Nuclear Spectroscopic Telescope Array (NuSTAR)." -- AstroU (talk) 02:31, 17 November 2014 (UTC) -- PS: FYI for additional future editing.

    These two are obviously about the same thing. Some comments:
    1. This one paper, that needs further corroboration before the proposed hypothesis should be included here. (ie. WP:TOOSOON.
    2. The neutrino's are at best traced to the vicinity of Sgr A*. (Given IceCubes angular resolution).
    3. Given that the temporal coincidence is with X-ray flares, the actual source of the neutrino's is more likely to be the accretion disc, not the black hole itself. (somewhat of a duh).
    4. More natural places to include a reference to this would be Sgr A*, accretion disc, or supermassive black hole.TR 14:03, 17 November 2014 (UTC)

    Headline-3: NASA finds ‘monster’ black hole in tiny galaxy

    QUOTE: "... But what really surprised astronomers is the supermassive black hole they found inside M60-UCD1. Lurking in the smallest galaxy, the black hole is five times the mass of the one at the center of our Milky Way galaxy. It has a mass equal to 21 million suns, and is 15 percent of the small galaxy's total mass – but less than 0.01 percent of the Milky Way’s total mass." -- AstroU (talk) 02:35, 17 November 2014 (UTC) -- PS: FYI for additional future editing.

    Again more natural content for supermassive black hole (which includes an overview detection candidates).TR 14:05, 17 November 2014 (UTC)

    Introduction article[edit]

    An editor over at Wikipedia:Village pump (idea lab)#Making wikipedia more accessible suggested creating introduction articles, which we already have of course, but this editor specifically mention this article as one that could use one. Oiyarbepsy (talk) 15:43, 9 December 2014 (UTC)

    Go make a black hole article on the Simple English Wikipedia. Weegeerunner (talk) 19:49, 11 December 2014 (UTC)
    That's not the same thing. Introduction to special relativity is here at standard English wiki. It's about having less technical information and math to be more accessible to those without an understanding of physics. Oiyarbepsy (talk) 20:51, 11 December 2014 (UTC)
    Simple English Wikipedia is for people who struggle with English, not people who struggle with advanced physics. I actually really like the original suggestion of having more introduction articles on Wikipedia, the only problem now is finding someone who will write one.
