The double split experiment does not prove wave/particle duality for light. It actually only proves that light is a wave, and another experiment proved that light is made of particles. Most of what people think they know about the experiment comes from Feynman theorizing about it.
in a very similar vein, i doubt most people are aware that there isn’t a fundamental theory of physics that accounts for neutrino mass. in the standard model, they’re just massless. there are theories that accurately describe neutrino mass eigenstates, to be clear, but it’s still unknown why their mass and flavor eigenstates differ.
