The total stress energy tensor of all matter elds is conserved, i.e. there is no net creation or destruction of overal 4-momentum r T (total) = 0 : However, as we saw in the case of a swarm of particles, the stress-energy tensor of any particular species sis not necessarily conserved: r T

The proper generalization of the Newtonian mass density in relativity is the stress-energy tensor T ij, whose 16 elements measure the local density of mass-energy and momentum, and also the rate of transport of these quantities in various directions. The stress-energy tensor comes from thinking of matter as a fluid - that is, even if you choose to think of matter as a bunch of particles, the stress-energy tensor at a given point in spacetime comes from averaging over all the particles in the vicinity of that point.

The covariant derivative of the dissipation stress-energy tensor determines the density of dissipation force acting on the matter and retarding the movement of flows of matter relative to each other. The dissipation stress-energy tensor is relativistic generalization of the three-dimensional viscous stress tensor used in fluid mechanics. Basically, the unified principle adopted by the successive authors (Kaluza-Klein, Weyl, Eddington, et al.) relied either on extra dimensions, or on an extension of the Riemannian theory with additional space-time curvatures introduced to yield the electromagnetic field characteristics, and where the stress-energy tensor regarded as provisional, will be eventually absent [2, 3, 4].

The electromagnetic field has a stress-energy tensor associated with it. From our study of electromagnetism we know that the electromagnetic field has energy density \(U=(E^2+B^2)/8\pi k\) and momentum density \(\vec{S}=(\vec{E}\times\vec{B})/4\pi k\) (in units where \(c=1\), with \(k\) being the Coulomb constant). From a physical perspective, the stress-energy tensor is the source term for Einstein's equation, kind of like the electric charge and current is the source term for Maxwell's equations.

One particular example of a stress-energy tensor which formally fulfils what you ask is the stress-energy tensor of charged dust. Dust has a stress-energy tensor written as $$T^{\mu u}_\mathrm{d} = \rho u^\mu u^ u $$ where $\rho$ is the mass density and $u^\mu$ its four-velocity. The current is then related to the quantities showing up in here as I am new to tensors and slightly confused with how one can "extract" the various Maxwell Equations as well as what the components are / represent.

It represents the amounts of energy, momentum, pressure, and stress in the space. The stress–energy tensor is defined as the tensor T αβ of order two that gives the flux of the αth component of the momentum vector across a surface with constant x β coordinate. In the theory of relativity, this momentum vector is taken as the four-momentum.

It represents the amounts of energy, momentum, pressure, and stress in the space. The stress–energy tensor is defined as the tensor T αβ of order two that gives the flux of the αth component of the momentum vector across a surface with constant x β 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] Gravitational stress-energy tensor is a symmetric tensor of the second valence (rank), which describes the energy and momentum density of gravitational field in the Lorentz-invariant theory of gravitation.
