Are you an "electric universe" believer? Black holes by definition can't emit EM radiation, so their only way to emit energy (ignoring hawking radiation which is tiny) is through gravitational waves. Due to the conservation of momentum, to be ejected from the core must be a result of some amount of momentum in the opposite direction.
