Sounds like you know a thing or two about physics. In your opinion, are particles like higgs bosons or gravitons or even electrons real? Coming from a coding perspective, making a physics simulation is about tradeoffs in effort/performance/complexity/fidelity, and there's often multiple ways to implement the same feature. From that perspective, theres no reason to expect a 1-to-1 mapping between theory and observed reality. How solid are the grounding posts that anchor the idea of particles to reality? Are electrons more real then bosons? Are they all just an implementation detail that makes the math look good?
