Light is both particles AND waves at the same time, since they only decide
where the the particles are at any given time when they are observed and
thus forced to reveal themselves. No particle of light has ever been used by
itself in a photograph, so waves are absolutely necessary in the description
of what we use. Aggregate is all we have (can see).

created. You cannot threaten any individual and escape the consequences."
