Solutions to einstein field equation

WebThe Einstein field equations are given by. (1) where is the stress-energy tensor, and. (2) is the Einstein tensor, with the Ricci curvature tensor , the metric tensor, and R the scalar curvature. The nonlinearity of the Einstein field equations stems from the fact that masses affect the very geometry of the space in which they dwell. 1. ^ Einstein, Albert (1916).
