I have seen and read a few different versions of the Einstein field equations (EFE). For example; R[itex]_{\mu\nu}[/itex] - [itex]\frac{1}{2}[/itex]g[itex]_{\mu\nu}[/itex]R = - 8[itex]\pi[/itex]GT[itex]_{\mu\nu}[/itex] , R[itex]_{\mu\nu}[/itex] - [itex]\frac{1}{2}[/itex]g[itex]_{\mu\nu}[/itex]R + g[itex]_{\mu\nu}[/itex][itex]\Lambda[/itex] = [itex]\frac{8 \pi G}{c^4}[/itex]T[itex]_{\mu\nu}[/itex] , and 8[itex]\pi[/itex]T[itex]_{\mu\nu}[/itex] = G[itex]_{\mu\nu}[/itex]
So which one is the true equation?? And if you could explain why they're different that would be great!
