privileged frame

The preferred frame of reference is the relative one.

Most (but not all) variants of this theory that support special relativity require a preferred frame.

The meaning of these is that , and measure the extent of preferred frame effects.

But his own, preferred frame of reference comes not from recent art history, but from mystery novels.

In order for these theories to be compatible with experimental results the preferred frame must be undetectable.

The Norton featherbed was the preferred frame, hence the Triton.

Michelson-Morley experiment, testing the direction dependence of the speed of light with respect to a preferred frame.

These field equations are manifestly covariant, i.e. there is no preferred frame of reference or absolute time.

In Einstein's special theory of relativity, all inertial frames of reference are equivalent and there is no preferred frame.

In 1905, Einstein published his theory of special relativity, which put forth a startling idea: There is no preferred frame of reference.

The dynamics of the scalar field is identified with that of an æther which is at rest in the preferred frame.

However, it has been suggested that loop quantum gravity violates background independence by introducing a preferred frame of reference ('spin foams').

In other words it is a preferred frame in principle only, in practice all inertial frames must be equivalent, as in special relativity.

In modern cosmology a preferred frame emerges naturally (the comoving frame) for universes whose behaviour is consistent with GR.

As a topological space, F is homeomorphic to GL(k, R) although it lacks a group structure, since there is no "preferred frame".

According to this model, Lorentz violations in the presence of preferred frames can lead to differences between the limiting velocity of massive particles and the speed of light.

As far as the CBR is concerned the distant galaxies provide a preferred frame, something that is anathema to SR or classical mechanics.

RQM could recover a Copenhagen-like view of the world by assigning a privileged status (not dissimilar to a preferred frame in relativity) to the classical world.

All of these experiments have thus far given negative results, so there is still no sign of the existence of a preferred frame or any other form of Lorentz violation.

There are many other Lorentz violating models in which, contrary to DSR, the principle of relativity and Lorentz invariance is violated by introducing preferred frame effects.

If there is a preferred frame of reference and the speed of light depends on the observer's velocity, then anomalous oscillations should be observable in the Earth-Moon distance measurements.

Einstein æther theories returned to prominence at the turn of the century with the paper Gravity and a Preferred Frame by Ted Jacobson and David Mattingly.

By 1997, MOND had been successfully incorporated in a stratified relativistic theory [Sanders], but as this is a preferred frame theory it has problems of its own.

As in Michelson-Morley experiments, the existence of a preferred frame of reference or other deviations from Lorentz invariance can be tested, which also affects the validity of the equivalence principle.

Emission theories obey the principle of relativity by having no preferred frame for light transmission, but say that light is emitted at speed "c" relative to its source instead of applying the invariance postulate.
