I provide a short overview of the current status of nuclear physics calculations using lattice Quantum Chromodynamics (LQCD). I demonstrate, at a very high level, how LQCD calculations are performed and how nuclear scattering data are extracted from these calculations, emphasizing the overlap between traditional nuclear many-body theory and LQCD calculations. I look at the Ω−Ω− system as a concrete example, and in so doing demonstrate the predictive nature of LQCD calculations as applied to nuclear physics.
