Their collisions offer a way to study this matter through gravitational waves. In this colloquium, I will discuss how tidal deformation connects gravitational-wave measurements to stellar structure, and how approximate universal relations help overcome degeneracies in these measurements. I will then explore the connections between microscopic nuclear interactions and macroscopic stellar properties, asking what observations can tell us about matter deep inside neutron stars. A neutron star\u2019s response does not just depend on its equilibrium structure, but also on how rapidly it is driven, how its constituents relax toward equilibrium, and how phase boundaries respond to perturbations. These effects connect dynamical tides and dissipation to the underlying matter physics. I will distinguish what observations already constrain from the signatures that remain difficult to measure, and discuss the prospects for learning more about dense matter when gravity waves."}
