QED heavyly relies on wave property of microworld: Fourie relationship between time and energy which we call Heizenberg principle. So, if you have no difference between 2 low-energy particles being located in time within Heizenberg undefined time span, you then can not say which particle is when. Symmetries require that those 2 particles "coming out of nowhere" have to be antiparticles (for a photon antiphoton is oppositely moving photon), so you may consider them "moving in opposite time direction", while in fact they both exist in "indefined yet" time.

I have not heard about attempts to consider time a dimension (a degree of freedom to move in). What would that mean - moving in time? Can we move in energy or in temperature? And what is the speed of such freedom of motion in time is? And how to express it mathematically?
