For mathematical ball, is the surface included in the definition of ball? Might one describe such ball as a set of surfaces; hence a composite/component? Thus the surface construct is always included in the definition of a ball.
Analogously, can one consider a real quantum as a composite of virtual quanta, most revealed on finer scale, such as for nearer to Planck scale; wherein the distinction between real (fermion mass spectrum?) and virtual becomes blurred?
