  Understanding the internal structure and spatial distribution of cosmic voids
is crucial when considering them as probes of cosmology. We present recent
advances in modeling void density- and velocity-profiles in real space, as well
as void two-point statistics in redshift space, by examining voids identified
via the watershed transform in state-of-the-art $\Lambda$CDM n-body simulations
and mock galaxy catalogs. The simple and universal characteristics that emerge
from these statistics indicate the self-similarity of large-scale structure and
suggest cosmic voids to be among the most pristine objects to consider for
future studies on the nature of dark energy, dark matter and modified gravity.
