Ah but you are forgetting E=hν. If you "stretch" a photon - by whatever undisclosed means you have in mind - you reduce its energy. So if you stretch it infinitely, you reduce its energy to zero. And then it's gone!Well, you wouldn't be surprised to know that any field is just an mathematical abstraction anyway, if we consider the field as an infinitely stretched photon (or wave of the electromagnetic field) then the field itself *is* the photon at it's lowest energy state that it can be at, which isn't zero because it had energy to begin with. But how to represent a non-zero energy when infinitely stretched? Well, maybe with perturbations happening seperated by time and space in just the right amount dispersed through it all? Which could then be the "quantum foam" that we can measure and being the non-zero background energy of spacetime.
