In this talk I will sketch how combining observational bounds from cosmology with insights from theoretical particle physics allows us to test gravity with unprecedented precision, in particular zooming in on the nature of dark energy. In doing so, I will highlight the interplay between gravitational wave constraints on gravity post-GW170817, data constraints from cosmic microwave background and galaxy clustering measurements, and theoretical priors on such theories from requiring them to be stable and well-defined.
