So the idea of this description of quantum physics called path integrals is that - simply speaking - nature takes all kinds of paths between two points in time at once, but they are weighted with different probabilities (for the experts: every possible way the fields can evolve in that period of time gets assigned a complex number called the amplitude)
They all get added together via the functional integrals(which, rob, aren't merely integrals over a real variable, but over entire functions, a problematic thing to define properly)
