- GR says that matter "interacts" with the surrounding space-time by probing
- its shape to find a geodesic. GR also says that space-time "interacts"
- with surrounding space-time and matter to determine the shape of that
- piece of space-time. I would say that GR does describe an interaction
- between the Earth and the Sun with the shape of space-time acting as the
- intermediary agent.
