  The intersection of the cosmic and neutrino frontiers is a rich field where
much discovery space still remains. Neutrinos play a pivotal role in the hot
big bang cosmology, influencing the dynamics of the universe over numerous
decades in cosmological history. Recent studies have made tremendous progress
in understanding some properties of cosmological neutrinos, primarily their
energy density. Upcoming cosmological probes will measure the energy density of
relativistic particles with higher precision, but could also start probing
other properties of the neutrino spectra. When convolved with results from
terrestrial experiments, cosmology can become even more acute at probing new
physics related to neutrinos or even Beyond the Standard Model (BSM). Any
discordance between laboratory and cosmological data sets may reveal new BSM
physics and/or suggest alternative models of cosmology. We give examples of the
intersection between terrestrial and cosmological probes in the neutrino
sector, and briefly discuss the possibilities of what different laboratory
experiments may see in conjunction with cosmological observatories.
