Dust cloud and energy momentum tensor
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. WebAug 1, 2024 · Harko et al. have demonstrated that the covariant derivative of energy-momentum tensor does not vanish in the theory giving the non-geodesic motion of a massive test particle and also it has...
