Description

I will discuss how the inclusion of a fluid's microstructure, namely the spin, dilation and shear parts of hypermomentum influence the Cosmological dynamics. In particular, imposing isotropy and homogeneity, I will introduce the concept of a Cosmological Hyperfluid; a generalization of the perfect fluid notion in Metric-Affine (Non-Riemannian) Geometries. Finally, I will discuss some applications of this construction and its relevance for the current challenges in cosmology.
