Dear Rod, Like Nathan Argaman I was impressed by your first manuscript. It is indeed a bohmian version of the two-time formalism of Aharonov et al. I have however several problems with this idea. I will only discuss briefly one here. My question is what is fixing your final boundary condition? In classical physics we have some freedom for choosing a Green function retarded advanced symmetric etc.. all of them are strictly equivalent if we use the good boundary conditions. For example you can write a field E like Ein +Eret= Eout + Eadv. Now in your theory you need two wave functions and this seems for me representing a breaking of this equivalence. What does it mean really to use such a future amplitude going backward in time? I have the feeling that your theory still needs a deeper justification.
