It's really Poincare's postulate, according to which *one* "absolute" cannot be *observed*. No beef here. Harald

What kind of Lorentzian relativity predicts a violation of its own invariance?? That doesn't make any sense. Anyway, if the "mere existence" of an "ether frame" violates LLT, then the realistic interpretation of QM violates LLT. - http://hep.princeton.edu/~mcdonald/examples/QM/hardy_prl_68_2981_92.pdf Harald

This has been explained to you. Where in the statement above is any medium mentioned??? It is now 'generally accepted' that the CMBR is the preferred 'rest frame' of our universe. This has really nothing directly to do with the question of a medium. However, it logically follows from the evidence. If you doubt the veracity of my claim here are but a few examples of this, http://www.tapir.caltech.edu/~kamion/CFP/Byer_Space_Time_Asymmetry_Research_CFP.pdf http://arxiv.org/PS_cache/arxiv/pdf/1006/1006.2697v2.pdf http://arxiv.org/PS_cache/astro-ph/pdf/0502/0502237v2.pdf http://www.scielo.br/scielo.php?pid=S0103-97332006000700014&script=sci_arttext&tlng=en There are, of course, many, many, more.

I could show you in later works but not in that one. BTW, what does term absolute mean to you?

In cosmological models based on the FRW manifolds of GR, the CMBR dipole=0 frame is also the cosmological frame in which the dust particles (galaxies) are at rest, due to the way the CMBR was generated. This is merely a symmetry of the manifold, and no "aether" is present, and the cosmological frame does not participate in the dynamics. In an expanding universe, it's not clear what "rest frame of our universe" means -- NOTHING is "at rest", and it is not possible to compute any sort of "average" [#]. But at each point in the FRW models there is a cosmological frame reflecting the symmetry of the manifold, and it can be determined via local measurements. [#] One might be able to compute an average over the visible universe, but that's not at all the entire universe. Tom Roberts |
