-- Virtual and Observable Aspects --
We must also examine some aspects of "virtual" and "observable." |
SUPERPOSITION DOES NOT ELIMINATE THE VIRTUAL SUBSTRUCTURE.
When the time aspects of the vector systems of Figure 13 are
considered, one can easily understand the problem. That is, the resultant of each of these "systems" is zero, and so one can say that the
vectorial "magnitude" of the system is zero since the magnitude of the
resultant vector is zero. However, in each case the "action" represented by each vector element actually occurs in a finite tiny
Δt. So: (1) The zero resultant must exist for a finite Δt, and (2) all the actions
indicated by the system component vectors actually occur in that Δt. The absolute value of the "activity per unit time per unit volume" of such a zero-resultant system thus has physical meaning, and one may refer to this notion as the "stress" on spacetime^{25}, or the "electrostatic scalar potential" of the system.
Note that this differs from the present definition of electrostatic scalar potential, which becomes just a special case of the more fundamental potential defined here.^{26} |
