Abstract: There are strong theoretical and observational arguments for why Einstein’s theory of gravity should fail. It is not a question of if, but rather a question of where and when! I will first summarize these arguments, and then discuss concrete predictions for three different astrophysical situations, where we are most likely to see this failure: 1) Kinematics in the galactic haloes, 2) Neutron star structure, and 3) Early Universe. Many of the experiments that can discover these anomalies are just around the corner.
