To date, studies of neutron stars have focused on better determining the equation of state, whose details are still debated. In this paper, it is argued that the uncertainty in the behavior of strong-field gravity introduces much greater differences in neutron-star properties than do current uncertainties in the neutron-star equations of state. Furthermore, it is shown that new observational developments allow for the measurement of the gravitational redshift of surface atomic lines, which is the cleanest source of information about the mass, radius, and spin of neutron stars.
