Many modified gravity theories attempt to explain dark matter or dark energy by modifying general relativity; however, these theories can be powerfully constrained by existing astrophysical data. I will discuss how isolated dwarf galaxies can be used to test Verlinde's Emergent Gravity, a theory that attempts to account for dark matter. In addition, I will discuss how higher-dimensional theories that attempt to explain dark energy can be constrained by the recent binary neutron star merger GW170817.
