Metric tensor calculation tool? [duplicate]
The Einstein field equations are
$G_{\mu\nu}+\Lambda g_{\mu\nu}=\kappa T_{\mu\nu}$
which would be easy enough to solve if not for all of the nonlinear dependencies on $g$ that the Einstein tensor $G$ ...

How to use Python to get mathematical expressions in General Relativity [duplicate]
I'd like to get the metric tensor that describes a non-rotating, uncharged, perfectly spherical black hole whose radius grows with time (it gains mass). For now, I have:
$g_{\mu\nu}=\begin{pmatrix}
-c^...
