Recently I heard that when a particle travels back in time it carries the opposite force to it traveling forward in time
For example if an electron travels back in time then it has positive charge.
I need to know if this is true or not and if so does if affect all types of particle such as;
Hadrons,leptons,baryons etc

More or less, yes, this is accurate. An electron going backwards in time would have a positive charge. A proton going backward in time has a negative charge. Their mass is still positive. But most of the other property (charge, parity, etc.) values would be reversed.

so does this apply to the particles involved in the Casimir effect?

Yes, the same basic rules apply to virtual particles.
 
thanks i needed reassuring on it
 
Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
