  In addition to the two standard solutions of the quantum field equations
having the form e^{+/-(iwt-ikx)}, there exist two additional solutions of the
form e^{+/-(iwt+ikx). By incorporating these latter solutions, deemed
"supplemental solutions", into the development of quantum field theory, one
finds a simple and natural cancellation of terms that results in an energy VEV,
and a cosmological constant, of zero. This fundamental, and previously
unrecognized, inherent symmetry in quantum field theory shows promise for
providing a resolution of the large vacuum energy problem, simply and directly,
with little modification or extension to the extant mathematics of the theory.
In certain scenarios, slight asymmetries could give rise to dark energy.
