This research demonstrates a unique solution to Einstein's equations for anisotropic matter, suggesting new theoretical insights in geometry.
The solution of Einstein’s field equations for static spherically symmetric spacetime metric with anisotropic internal stresses has been obtained. The matter has vanishing complexity and a spacetime metric that satisfies the Karmarkar condition and is conformally flat. It has been noted that there is only one solution that meets these three conditions. This has been shown as a proof of the theorem.
