If not, why do we include such a description for force interactions? It seems to me that physics implements virtual particles as a means to do calculations. If this is the case, what is the motivation in coming up with virtual particles that have properties that make little intuitive sense? Are there other ways to describe QFT without exchanging of virtual particles? From an outside perspective, it feels like when something is inferred from math, it can be described in more than one way. Thanks
