restrocausality like the TI intepretation?
Maxwell's equations don't change if we replace time by its negative. This doesn't imply
retro-causality ; the speed of propogation is constant.
Do you know http://en.wikipedia.org/wiki/Wheeler%E2%80%93Feynman_absorber_theory" [Broken]?
Maxwell's equations are incomplete without boundary conditions.
Causality is put in as a physical boundary condition in solving the wave equation.
Advanced solutions are also useful mathematically, but not as the physical result.
