We show that the Einstein-Cartan-Sciama-Kibble theory of gravity with torsion not only extends general relativity to account for the intrinsic spin of matter, but it may also eliminate major problems in gravitational physics and answer major questions in cosmology. These problems and questions include: the origin of the Universe, the existence of singularities in black holes, the nature of inflation and dark energy, the origin of the matter-antimatter asymmetry in the Universe, and the nature of dark matter.

These thoughts have occurred to me as well. Thanks for sending this paper. I think Sean Carroll wrote a paper with opposite conclusion - or maybe it was Max Tegmark?

Curvature-Torsion theory is the local gauge theory of the full Poincare group of Special Relativity, therefore it's surprising that it would not occur in Nature.t
