“…(4) and study the substantially larger frequency shift which should be observed with respect to the present experiments with vacuum optical cavities. This substantial enhancement is confirmed by the only modern experiment that has been performed in similar conditions: the 1963 experiment by Jaseja et al 9 at MIT. They were looking at the frequency shift of two orthogonal He-Ne lasers placed on a rotating platform.…”

Several theoretical arguments indicate that space-time may have the fundamental stochastic nature of a turbulent fluid. This view, where Lorentz symmetry represents an emergent phenomenon, has phenomenological implications for those 'ether-drift' experiments that look for the possible existence of a preferred reference frame. In fact, numerical simulations show that, in present experiments with vacuum optical resonators, it becomes non trivial to understand if an irregular instantaneous signal is just spurious noise or has a genuine physical origin. To obtain further checks, experiments with light propagating in gaseous systems are particularly interesting. In fact, the transformation matrix, which connects the effective space-time metric for light propagation in the laboratory frame to the corresponding isotropic metric in the hypothetical preferred frame, is a two-valued function for refractive index N = 1 + . This symmetry argument, when combined with the idea of a stochastic space-time, provides a new scheme where the small irregular residuals observed in all classical ether-drift experiments and in the 1963 MIT experiment with He-Ne lasers become consistent with the average Earth's velocity of 370 km/s which is obtained from the CMB observations. This remarkable agreement should motivate additional, precise tests with a new generation of laser interferometers.

“…This is shown in figure 1. Under such circumstances light travels between the two clocks in a straight line in an approximately inertial frame which is the same as that used in the performance of the many light speed measurements in which c is the reported value [7][8][9][10][11]. It is particularly noteworthy that the one-way experiment by Krisher et al [15] which searched for light speed changes resulting from rotation of the Earth extended 21 km across the surface of the Earth and appears to violate the inertial requirement.…”

“…The experiment is operated within the dimensions of the original Michelson-Morley apparatus where the frame is considered to be approximately inertial and where special relativity has been universally applied [2]. This negates any objections about rotating coordinates and non-inertial frames which are never raised in the original Michelson-Morley experiment or in any of the several modern versions of the experiment [7][8][9][10][11].…”

“…We also recall similar optical experiments made by Morley, Kennedy-Thorndike, Viennese experiment by Joose and others [13] [14] [15]. However, the term "constant" means independence on time, on spatial coordinates, on the direction of light propagation and, finally, on the properties of the light itself.…”

This article is devoted to the key concept of modern electrodynamics-the invariance of the speed of light. The general principle of relativity is considered in detail. Some critical remarks to the relativistic invariance and to the Lorentz transformations are presented. The general invariance of Maxwell equations is discussed. Different theoretical expectations for possible results of Michelson-Morley experiment and some physical consequences are considered. Some critical remarks to the notion of the light speed and its constancy are given. The relativistic law for velocity addition, including strangeness of a noncollinear addition and a superluminal motion, is discussed. Critical analysis of two works which proof the need for existence of an invariant velocity is consequentially made.
