SUMMARY
The discussion centers on the definition of a test body in the context of General Relativity, specifically addressing its behavior in space-time. A test body is defined as an object that follows a geodesic in space-time without influencing the curvature of space-time itself. The participants argue that while the test body adheres to a geodesic, its gravitational field should not alter the geodesic of the surrounding space-time, similar to the concept of a test charge in electrostatics. This distinction is crucial for understanding gravitational self-interaction and its implications on geodesics.
