    Tell me you don’t understand black holes using a lot of words.

    As far as gravity goes they are equivalent to the star that they collapsed from and just as deadly.

    The difference is that you can get that much closer before “impacting” with it, but you and superman would be fucked pretty much at the same distance from it.

    And I think you need a lot less than 300 writers to conjure an idea that leverage our fantasy in more and better ways.

      And an infinitely dense point in spacetime doesn’t necessarily exist: it’s just what general relativity predicts is at the center of a black hole.

      The last time our physical model of the universe predicted an infinite value, we ended up discovering new physics eventually (the ultraviolet catastrophe). (Edit: ultrasound was a typo).

        And an infinitely dense point in spacetime doesn’t necessarily exist: it’s just what general relativity predicts is at the center of a black hole.

        If the singularity at the center of a black hole didn’t exist, and was just extremely dense instead, would all of the other properties that we know is true about black holes be able to exist? For example we know that Sag A* and that one other black hole we ‘imaged’ give off no light, would that still be possible without a singularity?
