[astro-ph/0604145] Amplified Doppler shift observed in diffraction images as function of the COBE "ether drift" direction
 
Authors:C. E. Navia, C. R. A. Augusto
Abstract:We report results on an ``one-way light path'' laser diffraction experiment as a function of the laser beam alignment relative to the Earth's velocity vector obtained by COBE measurements of the Doppler shift in the cosmic microwave background radiation (CMBR). An amplified Doppler shift is observed in the diffraction images, and the effect is compatible with a ``dipole'' speed of light anisotropy due to Earth's motion relative to the ``CMBR rest frame'', with an amplitude of $\delta c/\bar{c}=0.00123$. This amplitude coincides with the value of the dipole temperature anisotropy $\delta T/\bar{T}=0.00123$ of the CMBR obtained by COBE. Our results point out that it is not possible to neglect the preferred frame imposed by the cosmology and they are well described by the Ether Gauge Theory (an extension of the Lorentz's ether theory) and it satisfies the cosmological time boundary condition.

Any comments on this paper? As the authors note in the conclusion, independant verification of the result is needed, but Fig 6 seems to be a reasonably clear result in support of the anisotropy of the speed of light.

Should it not have been posted a week earlier?

In the TUPI laser diffraction experiment, a complete set of measurements is made in only ten minutes.

I am very sceptical that it is actually an anisotropic velocity of light as it is so large, ~ 370 km./sec, and would have been picked up before.
