\[\nabla^2 \phi = - 4 \pi G \rho\]

also called as stress-energy tensor
describe the densities and flows of energy and momentum
all forms of mass-energy can be sources of gravitational fields
the stress-energy tensor \(T_{\mu \nu}\) acts as a source of the gravitational field

\[R_{\mu \nu} - {1 \over 2}g_{\mu \nu}\,R + g_{\mu \nu} \Lambda = {8 \pi G \over c^4} T_{\mu \nu}\]
