In the data of the ether-drift experiments there might be sizeable fluctuations superposed on the smooth sinusoidal modulations due to the Earth's rotation and orbital revolution.These fluctuations might reflect the stochastic nature of the underlying "quantum ether" and produce vanishing averages for all vectorial quantities extracted from a naive Fourier analysis of the data. By comparing the typical stability limits of the individual optical resonators with the amplitude of their relative frequency shift, the presently observed signal, rather than being spurious experimental noise, might also express fundamental properties of a physical vacuum similar to a superfluid in a turbulent state of motion. In this sense, the situation might be similar to the discovery of the CMBR that was first interpreted as mere instrumental noise.

“…Once the angle θ 0 is conventionally defined when one of the arms of the interferometer is oriented to the North point in the laboratory (counting θ 0 from North through East so that North is θ 0 = 0 and East is θ 0 = π/2), we can immediately use the formulas given by Nassau and Morse [23]. These are valid for short-term observations, say 3-4 days, where there are no appreciable changes in the cosmic velocity due to changes in the earth's orbital velocity around the Sun and the only time dependence is due to the earth's rotation.…”

In principle, by accepting the idea of a non-zero vacuum energy, the physical vacuum of present particle physics might represent a preferred reference frame. By treating this quantum vacuum as a relativistic medium, the non-zero energy-momentum flow expected in a moving frame should effectively behave as a small thermal gradient and could, in principle, induce a measurable anisotropy of the speed of light in a loosely bound system as a gas. We explore the phenomenological implications of this scenario by considering a new class of dedicated ether-drift experiments where arbitrary gaseous media fill the resonating optical cavities. Our predictions cover most experimental set up and should motivate precise experimental tests of these fundamental issues.

“…[1,2], where the kinematical parameters of the cosmic velocity V are not appreciably modified by the Earth's orbital motion around the Sun. In this case, by introducing the latitude of the laboratory φ, the right ascension α and the declination γ associated to V, the magnitude of the Earth's velocity in the plane of the interferometer is defined by the two equations [8] cos z(t) = sin γ sin φ + cos γ cos φ cos(τ − α)…”

Re-analyzing the data published by the Berlin and Düsseldorf ether-drift experiments, we have found a clean non-zero daily average for the amplitude of the signal. The two experimental values, A 0 ∼ (10.5 ± 1.3) · 10 −16 and A 0 ∼ (12.1 ± 2.2) · 10 −16 respectively, are entirely consistent with the theoretical prediction (9.7 ± 3.5) · 10 −16 that is obtained once the Robertson-Mansouri-Sexl anisotropy parameter is expressed in terms of N vacuum , the effective vacuum refractive index that one would get, for an apparatus placed on the Earth's surface, in a flat-space picture of gravity .
