Feynman's Path integral formulation

[cragar]

Does Feynman's path integral formulation violate relativity ,
we get path's that are faster than c.

Feynman paths are just a mathematical tool, they are not a problem, they can do whatever they want. The problem would arise if the probability amplitude for a particle to travel faster than c would come non-zero... And this is not happening.

Why didn't you post it in Quantum Physics? Would have received more attention...
