Where do you think the AI image model gets the data for what artist's impressions of astronomic phenomena should look like? From all the artists who painted these in the past.

Sigatarius A is not a stellar black hole now is it?

We don't know how supermassive blackholes form. It's a bit of a mystery.

My bet is that they are older than 14 bln years.

Including the ones that did it for self expression for free instead of an inaccurate visualization at the top of every space related article

Just like they can do after that niche job goes poof

Why is that?

because of the image’s inaccuracy, masqueraded as something one of our telescopes could visualize, but instead is a contrived make-work programme

They're probably not formed by the merger of stellar blackholes.

Yeah, that's what I thought. TFA says (unconditionally) that SagA was formed by direct collapse of gas clouds.

For a related visualization about size/mass of suns and black holes:

It's actually correct. The radius/diameter of a black hole is proportional to its mass.
