I enjoy conjecture and CGI and what-ifs. But the idea of primordial black holes being dark matter? Huge gravitational wells repulsing things? I’m a layman, so this seems as implied by word choice and emphasis.

What about the image shown which is a common depiction? It looks like a donut which we happen to be looking at from an aesthetically pleasing angle.
And why do we not see any stars between us and the darkness of the black hole? I mean there must be plenty of objects too far to be sucked in and yet in the path of our view.
And if it really is donut shaped then if it rotates 90⁰ we would see no hole just a thick line of the stuff circling it and yet we never see images like that.
The way it is usually verbally described however I would have thought a black hole is in the center of a sphere so that the image should just look like a circle (no hole) and yet I don’t ever recall seeing an image like that.
Not entirely sure what you mean, but the image in the thumbnail is taken from a video describing an old theory that stars might have a black hole at their center. It would just look like a star. You couldn’t see the black hole, but they visually cut out a section allowing you to see the center.
Why does an actual photo show the hole visible?
That’s a regular black hole not a star, you’re seeing a glowing disc of material orbiting the black hole’s event horizon
