From your first source: “One was a black hole, where mass/energy collapsed rapidly to a point…”

That is a false description of black holes in GR. It’s colloquially correct. But if we’re saying this is a rigorous argument, it’s a red flag.

Black holes are regions of spacetime within which space and time reverse. We don’t know what the singularity is—it’s a mathematical anomaly almost by definition—but the best models don’t suggest anything collapsing to a “point.”

We can do this because we understand chemical biology. When we’re talking about non-chemical extradimensional processes, pretending we can reason from first principles is philosophy. Not physics. Not science.
