So, if the electric field propogates like light - where each point on the field is like a new point source - how is that different than saying that all of space is filled with electrons?  Is it just that there's enough positively charge fields that the two cancel out?

Also mind bending is the thought that the field is radiatiating out from the electron each frame, but the electron itself can also move.

And when it does so, it leaves a gap behind it, in a shape of an expanding half-shell.

I know that magnetism is supposed to be created by moving electric charges, so it would have been good for this explanding half-shell to explain this, but my understanding is that the magnetic field travels in a circle around the direction of movement, while this gap is moving in the opposite direction.

There is also the problem that if electrons are forced to move in discrete increments of planck length, then when it moves, it's running into its own electric field.  Why doesn't the field repel it?  Is there some notion that fields ignore the source they came from?

Or, perhaps, the field is repelling it.  Could it be that "mass" or at least "inertia" is just a measure of how much objects are pushed back by their own electric fields?

And of course, what is the thing that's at the source of the field?  Is it a single pixel, or an intersection point of 8 pixels?  How does it get pushed?

For a bit, I was thinking that maybe the electron is indistinguishable from its field, and that somehow the field itself is what gets pushed - that there is some reul that allow sfor the apparent center of the propogation to change.  For instance, mabye when two fields of the same charge meet, there is some kind of propogating swap that goes on, like the tower of hanoi, or maybe some lamda calculus manipulation of a character string, that moves all points of the whole field away from the intersection.
