The distinction between quantum and classical physics is not merely one of resolution. If that were the case, then we'd have long since discarded classical physics as we developed the quantum variety.

The problem is gravity, a force so weak that we need an entire planet just to have a place to stand. Scientists are working on an experiment that can prove whether or not gravity is not a quantum field, and I'm quite confident they'll discover that it is not. https://phys.org/news/2024-11-gravity-quantum-entity.html

The problem is that there's no way to quantize gravity in a way that makes sense with our observations of how it works in macroacopic reality. Most attempts at a quantum description of the gravitational field as we understand it immediately blow up into incalculable infinities of gravitons and fail to explain gravitational time dilation at the same time.

I think the correct description of reality will require a perspective which hasn't previously been described in mathematic form. I don't think spacetime/gravity is quantized, I think that's an emergent property of the same underlying process that gave rise to our quantized fields for matter and energy.

Thank you for your unqualified opinion. Physics hasn't managed to solve its problems and gets caught up in its own illogical contradictions (string theory, dark matter, quantum foam, really?!) so what's wrong with metaphysics?

Quantization is part of the problem: it's a limitation of our measurement construct not an underlying truth of the universe. I'd gladly share additional research but it seems you've already made up your mind, so I can't force you not to remain ignorant.

Metaphysics has bigger questions to ponder and doesn't apply to physics. It's a branch of philosophy, not science.

And quantization was the solution to an even bigger problem in physics, the ultraviolet catastrophe.

We know that matter and energy are quantized because that's the only reasonable explanation for why blackbody radiation is distributed like it is. The classical Raleigh-Jeans law, which accurately predicts thermal radiation frequency at low temperatures, fails to do so for higher temps. Only quantizing the emission of photons produces blackbody radiation predictions which match our experiments.
