WebWe can express conservation of energy and momentum in terms of the stress-energy tensor. Recall that the physical meaning of the component Ttt is the energy density. To get the conservation laws, consider a small box with dimensions dx, dyand dz, and restrict our attention to the case of ’dust’, that is, a ﬂuid 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
