| dc.description | A spacetime endowed with an anisotropic fluid is proposed for the interior of a Schwarzschild black hole. The geometry has an instantaneous Minkowski form and is a solution of Einstein's equations with a stress tensor on the r.h.s. obeying all the energy conditions. The interior fluid is compressible, with time dependent shear and bulk viscosity coefficients. The energy density $ρ$ and the ''radial'' pressure $p$ observe the equation of state $p + ρ= 0$ (as for dark energy), with no pressures on $θ-$ and $ϕ-$ directions. However, the angular components of the viscous part of the stress tensor are nonvanishing and equals the energy density of the fluid. | |
