Gravitational Shooting Gallery: Sighting in on Black Holes

For the first time, nonlinear simulations of black hole flybys in modified gravity have been performed — test shots on the cosmic range. Comparing the scattering angles with analytics hit nearly the bullseye: the difference stayed within one degree. This paves the way for rapid gravitational wave te
