I think you indirectly are right: Pop science News articles that have “reality” in the headline about topics like string theory tend to have “artistic impressions” with random CG art just like this, and I bet that’s what the AI based this on.
But the more direct answer is no, that’s not how Calabi–Yau manifolds themselves are generally illustrated.
Does that mean your frontend will also be compatible with a Lemmy backend?
