In general relativity it is just one of many effects, another one of which is the emission of gravitational waves which lead to an instability of the system. That's why we are observing black hole mergers. That kind of thing does, of course, not exist in quantum mechanics. | |

In the ideal classical two-body system, it will not do this sweeping out, but in quantum, it is thought that it will do so. | |

The actual trajectory of planet isn't simply an ellipse, but an ellipse whose semi-major axis essentially sweeps out through 360 degrees over time so the classical case IS spherically symmetric over time. Does that sweeping out happen in a two body system? | |
