"In physics the Einstein aether theory, also called aetheory, is a generally covariant modification of general relativity which describes a spacetime endowed with both a metric and a unit timelike vector field named the aether. The theory has a preferred reference frame and hence violates Lorentz invariance."@en . . . . . . "4860678"^^ . . . . . . . . . . . . . . . . . . .
