I will describe how BOSS data is used to measure distances via the localization of the baryon acoustic oscillation feature and the rate of structure growth via the modeling of redshift-space distortion effects. I will then describe how these measurements can be combined with those of cosmic microwave background experiments in order to test models of dark energy, measure the sum of the mass of neutrinos, and test general relativity.
