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


Yes I am. I'm saying it's unknown if singularities actually exist and the article cited flat out states it: "It could be that, in real black holes, singularities don’t even exist."

But this article isn't the only place.

https://en.wikipedia.org/wiki/Gravitational_singularity

"Physicists are undecided whether the prediction of singularities means that they actually exist (or existed at the start of the Big Bang), or that current knowledge is insufficient to describe what happens at such extreme densities."


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


The paragraph isn't saying that because it's the next paragraph that does.

    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:

The way you decided to answer: "We don't even know what's inside a black hole" frustrates me because it was overly simplistic of a complicated matter and you resorted to cheap sleight of hand.

Clearly, what's inside is being debated and unknown from the link already provided, and this one also makes that evident:

Although I could spend time pointing out that the existence of black hole singularities is questionable in and of itself, I was more interested in the nature of singularities assuming they exist. Is what's inside physical? We don't know until we have a new scientific theory because, by definition, the laws of physics as we know them break down past the event horizon.


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


Yeah, maybe. Didn't stop Carl Sagan from entertaining the barest possibility of worm holes, though. Supporting my original claim: "We don't even know what's inside a black hole."
