Query: Dimensional reduction in causal set gravity   Results from a number of different approaches to quantum gravity suggest that
the effective dimension of spacetime may drop to $d=2$ 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."
