Spatial curvature endgame: Reaching the limit of curvature determination

C. Danielle Leonard, Philip Bull, Rupert Allison

Current constraints on spatial curvature show that it is dynamically negligible: $|{\Omega }_{\mathrm{K}}|\lesssim 5\times 10^{-3}$ (95% CL). Neglecting it as a cosmological parameter would b…
