Concise way of expressing the physicogeometric content of the gravitational field equations

It is observed that the Einstein field equations $R_{\mu \nu }$-(1/2)${\mathrm{Rg}}_{\mu \nu }$=8π${\mathrm{GT}}_{\mu \nu }$ are equivalent to the physicogeometric statement: A local spherical region of radius r containing energy with moment of inertia I has the physical volume V(r)=(4π/3)($r^3$+GI) in an associated free-falling frame of reference.
