WebWhereas black holes can be treated as perfect fluids under the above assumption, their behavior differs from that of cosmic dust in the universe. The energy momentum tensor for a perfect static fluid in an isotropic and homogeneous universe can be simply written using the density ρ and pressure p of the fluid as T 00 = ~Gρ and T 11 = T 22 = T ...
