What is the difference between a positive charge, protons, and a negative charge, electrons? What is the electric field made of? Why do like charges, +/+ and −/−, repel each other and unlike charges, +/−, attract each other? It turns out that there is a simple answer to these questions, and by simple I mean it is at the 5^th or 6^th grade level. The key idea is to observe the symmetries of +/+,  −/−, and  +/− charge configurations relative to the particle of which electric fields are made. And when we answer these questions it will turn out that the particle we “invent” or “discover” is the particle of which everything in the universe is made. By everything I mean electric fields, magnetic fields, photon fields, gravity fields, electrons, protons, neutrons, electricity, forces, both pushes and pulls, dark matter, and dark energy—ergo a TOE. Of course, that TOE will have some complex and subtle aspects or parts.
