WebAug 2, 2024 · More specifically, the stress-energy tensor of an ideal fluid is given by (in +—- convention), where is the energy density, the pressure, and the 4-velocity of the fluid’s rest frame. Setting the pressure to zero would result in . Note that the pressure is generally not negligible in cosmology. 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.
