Dust cloud and energy momentum tensor
WebThe element of the stress–energy tensor represents the flux of the μ th-component of the four-momentum of the electromagnetic field, , going through a hyperplane ( is constant). It represents the contribution of electromagnetism to the source of the gravitational field (curvature of space–time) in general relativity .

WebWe all know that the energy-momentum tensor for dust is just T α β = ρ 0 v α v β, where ρ 0 is the mass density in the dust's rest frame and v α is the dust's four-velocity. I'm trying to … Webmatter and energy in the universe by a perfect fluid. We discussed perfect fluids in Section One, where they were defined as fluids which are isotropic in their rest frame. The energy …
WebMar 22, 2024 · From the Lorentz transformation property of time and position, for a change of velocity along the x -axis from a coordinate system at rest to one that is moving with velocity v → = ( v x, 0, 0) we have. (9.1.1) x ′ = γ ( v) ( x − v / c t), (9.1.2) t ′ = γ ( t − x v x / c 2), we can derive that energy and momentum behave in the same way, 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
