WebIn its own referential S, this cloud has an energy density ρ0=m0n0 where m 0 refers to the mass of a dust particle and n 0 the number of particles by unit of volum. By definition, as the cloud stands at rest in its proper referential, there is no kinetic term. WebWhereas black holes can be treated as perfect fluids under the above assumption, their behavior differs from that of cosmic dust in the universe.

"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.
