Einstein Field Equations

Posted on 18th Jul 2025

The Einstein field equations (EFE) may be written in the form: \[ R_{\mu \nu} - {1 \over 2} g_{\mu \nu}\,R + g_{\mu \nu} \Lambda = {8 \pi G \over c^4} T_{\mu \nu}\] where \(R_{\mu \nu}\), is the Ricci curvature tensor, \(g_{\mu \nu}\), is the metric tensor, \(\Lambda\), is the cosmo...
