Lorentz violation in gravity: why, how, where



Abstract "Recent approaches to quantum gravity question the role of Lorentz invariance as a fundamental symmetry of Nature. This has implications for most of the observables in gravitational physics, also at low-energies. In this talk I will present  a couple of these models (Horava gravity and Einstein-aether) and describe how they affect the predictions for binary pulsar and cosmological observations. I will finally show which are the constraints form these observations on Lorentz-violating theories of gravity."
