Time‐Symmetric Action‐at‐a‐Distance Electrodynamics and the Structure of Space‐Time
Department of Physics, Clark University, Worcester, Massachusetts 01610 U.S.A.
We argue that the concept of “material point particle” is incompatible with the force laws of action‐at‐a‐distance electrodynamics, and that the trajectory of a particle is analogous to a string in static equilibrium. Geometrical arguments lead us to consider a time‐symmetric interaction law, and a microscopic electromagnetic field‐strength tensor which is no longer antisymmetric. As a consequence the rest mass of a particle, in our theory, is no longer constant; however its averaged variation is still null.
Keywords: relativity theory, action‐at‐a‐distance electrodynamics, time symmetry
