Modified Einstein-Cartan Gravity and its Implications for Cosmology
  We propose a modification of Einstein-Cartan gravity equations. The modified
cosmology departs from the standard model of cosmology for small Hubble
parameter. A characteristic Hubble scale h0, which is intrinsically related to
cosmological constant, marks the boundary between the validity domains of the
standard model of cosmology and modified cosmology. For large Hubble parameter,
the standard model of cosmology is restored. In the opposite limit of small
Hubble parameter, which is the case for present epoch, Lorentz-violating
effects would manifest themselves. One of the implications is that there may be
no need to invoke dark matter to account for cosmological mass discrepancies.
