我们在背景因果集上模拟了无质量标量场从源到探测器的经典传输。这些预测与连续统的预测没有显著差异。因此，对长度和持续时间引入一个内在的不精确性--或者更具体地说，用一个底层的离散结构取代洛伦兹流形--不需要破坏通常的传播动力学。
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.
