Steady-state versus viscous cosmology

  • M. Heller

Hoyle's steady-state cosmology and relativistic Robertson-Walker world models with a constant bulk viscosity are briefly reviewed and compared. It is shown that, although they are identifical from a purely formal point of view, the interpretation of Hoyle's model in terms of viscous dissipation would be physically unrealistic.
