An isotropic expansion for the QGP is proposed in the curved Kasner spacetime for an experimental configuration with a three-dimensional set of beams. The fluid of relativistic particles has no shear viscosity but the nonzero bulk viscosity ζ is time dependent and its value could explain the enormous entropy per baryon of our Universe. In addition, ζ equals the bulk viscosity of the anisotropic compressible fluid conjectured for the interior of a black hole.
