Hello, I am not yet well-versed in quantum theory of the vacuum, but I certainly have encountered it everywhere I have turned in my studies. Since my electron paper is unwieldy I want to run by folks my thoughts of percolations in the vacuum. So many people have spoken of "electrons and positrons popping in and out", I used to hate this line. Now, it's clear the vacuum must be something like this. Given an electron field, at smaller and smaller distances the electric field gets very high. Consider the possible effects of combing the populations of dipoles of the virtual field. Picture the electron on the left of the page. Now consider the fates of dipole pairs nearby, of different orientations. I presume the vacuum cooks up a random offering. For any pair with the electron further away to the right, and the + charge closer in, consider the force on the particles separately, and then as a pair. In this case, the + is attracted inward, but the - is repelled, to a lesser extent. Therefore, as a unit the dipole will be pulled in a bit in its brief life. The +/- will be slightly separated so its lifetime will be longer. The opposite case behaves oppositely: the -/+ are speeded to annihilation. Divergence of the field is posited to "charge" . Realize also, that given a polarization field with divergence, its negative also constitutes a charge field. See, then, that if the vacuum field is 'combed' as I described, there well be a net population of dipoles acting favorably to sustain the electric field. Now consider the +/- pair migrating a bit inward. If there is a poloidal magnetic field, as the particles cross it they will be accelerated oppositely, and sideways. This is harmonious with the current flow assumed in my inhomogeneous model.
