Abstract
We model the classical transmission of a massless scalar field from a source to a detector on a background causal set. The predictions do not differ significantly from those of the continuum. Thus, introducing an intrinsic inexactitude to lengths and durations—or more specifically, replacing the Lorentzian manifold with an underlying discrete structure—need not disrupt the usual dynamics of propagation.
