Decades of research have established that general relativity is compatible with negative mass. Recent studies have highlighted its significant role in the dynamics of gravitational waves and dark energy. While numerous papers have investigated the gravitational dynamics of negative mass, the goal of this paper is distinct. Our objective is to address a gap in the literature by deriving a negative mass solution directly within the framework of general relativity rather than relying on assumptions. Traditionally, studies have introduced negative mass by simply substituting a positive mass term with a negative one. In contrast, our findings demonstrate that a negative mass solution can be naturally derived from general relativity without such assumptions.
