Abstract: I will review Horava's proposal for quantum gravity making emphasis on its low-energy limit. In this limit the theory reduces to general relativity coupled to a scalar field with time dependent vacuum expectation value (khronon) that breaks Lorentz invariance. I will discuss some phenomenological aspects of this "khrono-metric" model and the observational bounds on its parameters.
