Discreteness And The Transmission Of Light From Distant Sources, Fay Dowker, Joe Henson, Rafael Sorkin

Physics - All Scholarship

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.
