Query: Primordial Rotation of the Universe and Angular Momentum of a wide range
  of Celestial Objects   The origin of rotation or spin of objects, from stars to galaxies, is still
an unanswered question. Even though there are models which try to explain this,
none of them can account for the initial impulse that gave rise to this spin.
In this paper we present that a cosmological model that contains a term
involving the primordial spin of the universe can explain how these objects
acquired the property of spin. This model also gives a natural explanation for
the quadratic scaling of angular momentum with mass. Again, from this model,
the background torsion due to a universal spin density not only give rise to
angular momenta for all structures but also provide a background 'centrifugal
term' acting as a repulsive gravity accelerating the universe, with spin
density acting as effective cosmological constant.
