The Pulsoid Theory A Light vector, heuristically described in two dimensions, has coordinate axes, which are diameters of an ellipse, one axis is linear, the other cyclical.  The coordinate axes express time; the vector expresses direction. The two-dimensional heuristic vector is actually a complex tensor of a dynamic ellipsoid, which is referred to as a Pulsoid. Pulsoids exist and expand nonlinearly, cyclically, and quaquaversally dependent on the unit values and ratios of their constituent solitons. Thus, the internal structure of Light . . . and all other phenomena. And, thus, at once, is explained the confusion concerning both the definition of time, which is a dimension that is, simultaneously, linear and cyclical; and, the enigmatic manifestation of Light as either a particle or a wave. It is the Pulsoid and its relationship to a definition of Infinity as both the Singularity and a duality that is the crux of the Equilibrium Theory of Reality, which is commonly referred to as the Pulsoid Theory.
