Recent approaches to quantum gravity question the role of Lorentz invariance as a fundamental symmetry of nature. This has several implications for cosmology, both at the fundamental and at the observational level. At the fundamental level it allows for new ideas for dark energy or dark matter. At the observational level, it predicts deviations from the standard ΛCDM paradigm at the level of perturbations. These can be tested very accurately with current data from CMB and large scale structure. In my talk I’ll elaborate on the previous aspects.
