ManyWorlds

A flicker of sunlight catches my eye. Is it:

a photon emitted eight minutes ago by a hydrogen atom in the solar atmosphere, ricocheting off a smooth surface and striking a cell in my retina?
a local disturbance in the electromagnetic field, the unique mathematical solution to a set of differential equations and boundary conditions?
a cascade of neural impulses in my brain, woven together into conscious perception?
a massively distributed correlation of quantum mechanical wavefunctions?
a wink from my wife at the other end of the park bench?

Answer: all of the above. I choose the final interpretation, slide over, and give her a kiss.
