Gravitational wave observations will probe nonlinear gravitational interactions and thus enable strong tests of Einsteins theory of general relativity. We present a numerical relativity study of the late inspiral and merger of binary black holes in scalar-tensor theories of gravity. We consider binaries inside a scalar field bubble, including in some cases a potential. We demonstrate how an evolving scalar field is able to trigger detectable differences between gravitational waves in scalar-tensor gravity and the corresponding waves in general relativity.
