Abstract: An isotropic expansion for the QGP is proposed in curved Kasner spacetime foran experimental configuration with three dimensional set of beams. The fluid ofrelativistic particles has no shear viscosity but the nonzero bulk viscosity$\zeta$ is time dependent and its value could explain the enormous entropy perbaryon of our Universe. In addition, $\zeta$ equals the bulk viscosity of theanisotropic compressible fluid conjectured for the interior of a black hole.
