In other words, the Lagrangian for this theory in a dynamical spacetime consists of the usual Einstein-Hilbert action, a second-order kinetic term for the tensor field T , and a potential energy term for T . If we take the equations of motion associated with this metric, we can see that a field configuration where gab = ηab and T = T throughout spacetime will solve the equations of motion provided that
