Mathematica(@mathemetica):Einstein’s field equations (with cosmological constant) in fully expanded form. Gμν + Λgμν = 8πG/c⁴ Tμν The large panel below shows the complete coordinate expansion of the Einstein tensor Gμν expressed entirely in terms of the metric tensor gαβ and its first- and second-order partial derivatives - the explicit differential equations at the heart of general relativity.
