From: Surfer on 13 Feb 2010 01:52 This is a very interesting discovery. Originally made here: Lunar Laser Ranging Test of the Invariance of c Daniel Y. Gezari http://arxiv.org/abs/0912.3934 Abstract: The speed of laser light pulses launched from Earth and returned by a retro-reflector on the Moon was calculated from precision round-trip time-of-flight measurements and modeled distances. The measured speed of light (c) in the moving observers rest frame was found to exceed the canonical value c = 299,792,458 m/s by 200+/-10 m/s, just the speed of the observatory along the line-of-sight due to the rotation of the Earth during the measurements. This is a first-order violation of local Lorentz invariance; the speed of light seems to depend on the motion of the observer after all, as in classical wave theory, and implies that a preferred reference frame exists for the propagation of light. However, the present experiment cannot identify the physical system to which such a reference frame might be tied. And there is additional analysis here: Lunar Laser-Ranging Detection of Light-Speed Anisotropy and Gravitational Waves Authors: Reginald T Cahill (Flinders University) http://arxiv.org/abs/1001.2358 Abstract: The Apache Point Lunar Laser-ranging Operation (APOLLO), in NM, can detect photon bounces from retro-reflectors on the moon surface to 0.1ns timing resolution. This facility enables not only the detection of light speed anisotropy, which defines a local preferred frame of reference - only in that frame is the speed of light isotropic, but also fluctuations/turbulence (gravitational waves) in the flow of the dynamical 3-space relative to local systems/observers. So the APOLLO facility can act as an effective "gravitational wave" detector. A recently published small data set from November 5, 2007, is analysed to characterise both the average anisotropy velocity and the wave/turbulence effects. The results are consistent with some 13 previous detections, with the last and most accurate being from the spacecraft earth-flyby Doppler-shift NASA data.

What to say no gravitational waves and lightspeed variance............. Ooooops Loooky looky no hands....

You either have lightspeed and get distance from time, or you have distance and time to get lightspeed. To model distance from measurements assuming lightspeed then use that model to determine lightspeed mght only reveal errors in the model. Look up Kopeikin, Jupiter, and the speed of gravity. It didn't work out for Kopeikin. The van Allen belts, the ionosphere, the atmosphere... are all moving refractive media. > The measured speed of light (c) in the moving observers > rest frame was found to exceed the canonical value c = 299,792,458 m/s > by 200+/-10 m/s, just the speed of the observatory along the > line-of-sight due to the rotation of the Earth during the > measurements. Refractive media are moving with the observatory. Add SAGANC EFFECT and pulse chirping. One doesn't see it as a strong claim. > This is a first-order violation of local Lorentz > invariance; the speed of light seems to depend on the motion of the > observer after all, as in classical wave theory, and implies that a > preferred reference frame exists for the propagation of light.

A recently published small data set from November 5, 2007, "small data set from November 5, 2007" No mention of the Sagnac effect between moving frames.

You are going to make Einstein crawl up out of his grave, just to better explain all of this. ~ BG |
