Observable consequences of the hypothesis that the observed universe is a
numerical simulation performed on a cubic space-time lattice or grid are
explored. The simulation scenario is first motivated by extrapolating
current trends in computational resource requirements for lattice QCD into
the future. Using the historical development of lattice gauge theory
technology as a guide, we assume that our universe is an early numerical
simulation with unimproved Wilson fermion discretization and investigate
potentially-observable consequences. Among the observables that are
considered are the muon g-2 and the current differences between
determinations of alpha, but the most stringent bound on the inverse lattice
spacing of the universe, b^(-1) >~ 10^(11) GeV, is derived from the
high-energy cut off of the cosmic ray spectrum. The numerical simulation
scenario could reveal itself in the distributions of the highest energy
cosmic rays exhibiting a degree of rotational symmetry breaking that
reflects the structure of the underlying lattice.
