Abstract
Results from a number of different approaches to quantum gravity suggest that the effective dimension of spacetime may drop to at small scales. I show that two different dimensional estimators in causal set theory display the same behavior, and argue that a third, the spectral dimension, may exhibit a related phenomenon of "asymptotic silence."
