The Einsteinian theory views gravity as the curving of space around every mass. This curvature adjusts to any and all masses in motion, which manifests as a gravitational wave.
Storm in a cup503.5 kt
Constrained waves adjust to their container. In a circular pool, the motion reinforces itself, eventually resulting in a jet of water.
