WebNov 8, 2024 · The stress–energy tensor is defined as the tensor Tαβ of order two that gives the flux of the α th component of the momentum vector across a surface with constant xβ coordinate. In the theory of relativity, this momentum vector is taken as the four-momentum. In general relativity, the stress–energy tensor is symmetric, [1] T α β = T β α. WebI shall argue that mass-energy-momentum density, as described in rela-tivity theory, is not an intrinsic property of material systems, but a property they have only in virtue of their relation to spacetime structure, in particular to the metric tensor g . Nevertheless, the non-vanishing of a mass-energy-momentum density tensor T
