What To Do Next?

Since I believe that:
1. Gravity is nothing more than an imbalance in electric fields
2. Magnetism is nothing more than a minor effect of moving charges/moving fields
3. Atomic physics and nuclear physics cannot be done right without having the electromagnetism right to start with,

Then it seems clear that the most vital thing to figure out is the business of charged particles and their associated electric fields and how they interact with each other. But either I'm totally lacking in imagination or totally lazy or both those things, because I'm just not certain where to go next.

My present feeling is that what we call magnetism is mostly a simple result of propagation delay, i.e., the effects of the distortion of electric fields as they move through the aether. O.K., so? What do I need to do next?
