I will discuss the dynamics of a collapsing (homogeneous and isotropic) universe, and show that torsion induced interactions can prevent the universe from reaching a singularity, but lead to a regular bounce. This dynamic can be understood as the formation of fermionic condensate(s), which lowers the energy density of the fermions effectively slowing down the gravitational collapse. Before a singularity is reached, in fact, the null energy condition gets violated, and the energy density of the fermionic field reaches zero. At this point all the initial energy has been converted in a negative pressure, which causes the universe to re-expand. This process is possible because the energy density lost by the fermionic field is simply converted in the more energetically favourable condensate state, and will eventually come back as the universe cools down and gets bigger. I will discuss both classical and semi-classical treatment of this problem.
