A stone falls into a pond, and ripples spread across the water. Similarly, a black hole resting in the void may encounter a gravitational wave or a cloud of gas. It does not remain indifferent: its surface (the event horizon) bends slightly, like a stretched membrane under the weight of a drop.

In the dense core of a star cluster, three black holes converge in a dangerous dance. The motion is chaotic — trajectories tangle like balls of yarn. Then one hole is ejected, while the other two remain on an elongated orbit. Such a pair continues to spiral inward and eventually merges, producing a burst of gravitational waves.
