Why don’t we see superposition states for macroscopic objects?

.

A superposition state is *not* any “overlapping” of multiple physical states.

.

A superposition state is a wave function, which is not a physical wave located in physical space.

Instead, it is a mathematical tool to calculate probability distributions.

EM waves are not photon wave functions because EM waves are physical, while wave functions are mathematical.

In addition, the electromagnetic fields are observable (e.g. with an oscilloscope) while Schroedinger wave functions are not observable, *even in principle*. Clearly, then, the fields are not wavefunctions, are physical, observable fields, rather than merely what you take the modulus-square of to obtain the probability of finding a photon somewhere. The existence of some “wavefunction of the photon” is not a fully settled issue.
