Description
Metric affine gravity (MAG) represents an extension of general relativity (GR) in which an independent connection other than the Levi-Civita one is present. In MAG there are three tensors describing the geometry of spacetime, curvature, torsion and nonmetricity. And two tensors related to matter's behaviour, the stress energy tensor and the hypermomentum. After reviewing the main features of metric affine gravity, I will show how MAG changes the GR predictions for cosmology.
