UNCHARGED SPATIAL (MASSLESS) SYSTEM VECTOR
 -- (Figure 1) --

          This is the geometer's abstract vector, consisting of a "point in motion."  (Actually, it is a "smeared point," for example.)  However, so ingrained is the concept of a "point in motion" velocity vector that we now consider it to be "natural" because of its total familiarity.  But simply ask, "WHAT is in motion?"¹⁷ and you immediately see the difficulty.  To have a WHAT, one must "stop the action" (detect or measure), separating "static" from "non-static."  Acceleration and other vectors, etc. have also been derived by the geometer and utilized in similar fashion.  All are massless.
