On certain relationships between cosmological observables in the Einstein-Cartan gravity

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

We show that if one takes into account Penrose’s conformai technique in the Einstein-Cartan gravity, it is possible to obtain a relation between Hubble’s expansion and Birch’s rotation of the Universe at space-like infinity. This relation also leads to the final reduction of the gravitational coupling to a dimensionless quantity of order unity at space-like infinity. Initial-value equations at space-like infinity in the Einstein-Cartan gravity can be used as a starting point to study the structure formation and evolution of the Universe with Ω = 1. Current measurements of the expansion and rotation of the Universe favour the massive spinning particle as a candidate particle for dark matter.
