SUMMARY
The discussion centers on the concept of gravitational work when two massive objects are moved away from each other. The consensus is that the work done by gravity is negative for both objects when they are separated, contradicting the initial statement that it could be positive for one. The reasoning highlights that gravitational force always acts to pull objects together, resulting in negative work when they are moved apart.
