Okay, I see what you did there. But you're not understanding what you're reading.

    According to theory, within a black hole there’s something called a singularity. A singularity is what all the matter in a black hole gets crushed into. Some people talk about it as a point of infinite density at the center of the black hole, but that’s probably wrong — true, it’s what classical physics tells us is there, but the singularity is also where classical physics breaks down, so we shouldn’t trust what it says here.

The above paragraph isn't saying that a singularity doesn't exist, just that it may not be a point of infinite density.

    In a very specific mathematical case, the singularity in a spinning black hole becomes a ring, not a point. But that mathematical situation won’t exist in reality. Others say that the singularity is actually a whole surface inside the event horizon. We just don’t know. It could be that, in real black holes, singularities don’t even exist.

The mathematical case may be specific, but it's not rare and yes, it exists in reality. The math on this is pretty tight. We can even calculate the radius:

    Wormholes are theoretically possible, given the right conditions. But those conditions almost certainly would never exist in the real universe.

Yes, theoretically possible, but as this journalist points out, incredibly unlikely, I.E. not a physical solution at all, but an entirely mathematical artefact.
