Query: An Isolated Gravitational Dipole Moment Placed at The Center of the Two
  Mass Pole Model Universe   The unexpected dynamic shift of the center of mass for a rotating hemisphere
is shown to produce the general relativistic dipole field in the macroscopic
scale. This prompts us the question of what might be its cosmological
implications. The uniformly rotating sphere has the effect of the latitude
dependent mass density distribution as reported by Bass and Pirani which is the
cause of the `induced centrifugal force' in the Thirring's geodesic equation
near the center of the rotating spherical mass shell. On the other hand, one
would expect the constant acceleration of the mass components may cause a
general relativistic gravitational field. The component-wise accumulation of
this effect has been shown to appear as the non zero gravitational dipole
moment in a rotating hemispherical mass shell. The present report discusses
this non-Newtonian force experienced by a gravitational dipole moment placed at
the center of the two mass pole model universe and its relevance to the
observed anomalous red shift from far away galaxies.
