Einstein–Cartan, Bianchi I and the Hubble diagram

We try to solve the dark matter problem in the fit between theory and the Hubble diagram of supernovae by allowing for torsion via Einstein–Cartan’s gravity and for anisotropy via the axial Bianchi I metric. Otherwise we are conservative and admit only the cosmological constant and dust. The failure of our model is quantified by the relative amount of dust in our best fit: Ω _m0= 27 ± 5 % at 1 σ level.
