Einstein Aether Theory
In physics the Einstein æther theory, also called æ-theory, is a controversial generally covariant generalization of general relativity which describes a spacetime endowed with both a metric and a unit timelike vector field named the æther. In particular such theory has a preferred reference frame and so is not Lorentz invariant.
