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.

Famous quotes containing the words einstein and/or theory:
“I found out that a doctor’s wife needs the understanding of an Einstein and the patience of a saint.”
—Daniel Mainwaring (1902–1977)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
