Description
In this poster, we present recent results on the application of the minisuperspace (MSS) formalism to General Relativity in the static, spherically symmetric sector. We investigate the correspondence between the MSS approach and the standard formulation of Einstein's field equations, demonstrating that the formalism reproduces a known non-trivial spacetime solution while providing a consistent physical interpretation of its properties. Furthermore, the construction is extended to include a cosmological constant, leading to a new exact solution. Its physical characteristics are explored through an analysis of test-particle and null geodesic motion, with particular emphasis on the resulting orbital structure. These results illustrate the potential of the minisuperspace formalism as a powerful tool for constructing and interpreting exact solutions of Einstein's equations, contributing to the mathematical foundations of gravitational theory.
