Quantum Double-Slit: Did the Particle Go Through Both Slits?

This post tackles a central question in the quantum double-slit experiment: how do particles create an interference pattern? Using a simplified 'double-door' analogy, the author argues that neither the particle itself nor its wave function passes through both slits simultaneously. A particle can only occupy one position, while the wave function resides in possibility space, not physical space. The interference pattern doesn't arise from the particle or wave function's movement in physical space but is linked to the wave function's evolution in possibility space. The post ends on a cliffhanger, promising to explain the source of the interference effect in a future installment.
