A black hole does not necessarily dominate the gravitational influence in a system with a more massive object; instead, both will orbit around their common center of mass. This principle applies to all celestial bodies, including stars and black holes, which are not stationary but move in relation to each other. For example, Cygnus X-1, a well-studied black hole, orbits a more massive star, demonstrating that even the most massive objects can have companions that exert significant gravitational influence. The concept of the barycenter illustrates that all bodies in a system, regardless of mass, participate in this orbital dynamic. Understanding these interactions is crucial for comprehending the behavior of celestial systems.
