So reality is imaginary.
As we always subjected, we all all actors on the stage …of someone’s dream.
To the photon particle, the wave function can only be imaginary. The particle exists in linear space only, so it lacks the variability to sense something in planar space. The wave ‘function’ lacks a third variable of space so when it arrives at a surface in a volume universe, it collapses into two of the three variables of volume.
