Description
Recent approaches to quantum gravity suggest abandoning
Lorentz invariance as a fundamental symmetry of Nature. This
introduces new gapless degrees of freedom in the gravity
sector. I will review the consequences for cosmology of the
minimal set-up and present the constraints from different
observations. If I have time, I’ll briefly comment on the
successful merging of these ideas with massive gravity.
