It's not a singular source of gravity at the center though, it's the collection of all mass in the galaxy interacting with each other as well. Like a daisy chain of gravity, which explains why it looks like a spiral instead of an evenly distributed circle.
(I think anyway, I just made it up, I'm not learned in this area, just a HN shitposter)
Right, not a point source and not exactly a blob either; more like swirls. I'm not learned in this area either.
