It’s not too often that a giant of physics threatens to overturn an idea held to be self-evident by generations of physicists. Well, that may be the fate of the famous Penrose Singularity Theorem if we’re to believe a recent paper by Roy Kerr. Long story short, the terrible singularity at the heart of the black hole may be no more.
Just because a model/theory/hypothesis, which is a simplification, declares that a black-hole contains a “singularity”, doesn’t mean that Universe embodies that particular simplification.
I read years ago, that in String Theory, it isn’t a singularity, rather it’s something like a proton, a stringball: complicated-as-hell ( I saw a Quanta page on protons, yeeks those are screwy ), and all it has to do is be smaller than the event-horizon, and we can’t sample it, or measure it.
IOW, it is entirely possible for it to occupy volume, not be “infinitely tiny”, which is an absurd concept, to begin with.
That seems much more likely reality, to me.
1st, rule-out the nonsensical, like 0-volume particles ( including singularities ),
and 2nd, consider what-remains, & study those.
3rd, never mistake a theory/simplification/model for Universe-itself, or your assuming is your bogo-ground, and you’ve no excuse for knowingly doing that.
Obviously, accidentally creating a singularity on Earth would prove that singularities exist, but would kill all our planet’s life, unless it “evaporated” rather quickly.
