What is the metaphysical explanation for what mainstream science calls "waveâ€“particle duality"?
The "waveâ€“particle duality" is a concept of mainstream science.
"Waveâ€“particle duality postulates that all particles exhibit both wave and particle properties. A central concept of quantum mechanics, this duality addresses the inability of classical concepts like "particle" and "wave" to fully describe the behavior of quantum-scale objects. Standard interpretations of quantum mechanics explain this paradox as a fundamental property of the Universe (...)"
