So what, if there was no reason to mention it? What I mention in the discussion I can support, if necessary, with additional arguments. Sorry, but from our "frame of reference" the CMB radiation does not look homogeneous at all. It becomes homogeneous only if we look at it from the CMBR frame. This is how it is defined, essentially. Of course, it can be tested - and could easily seen to be false. There is an interesting difference to Newtonian theory that there is no Galilean symmetry. As usual in a discussion, I inform about what is fact in the particular situation, and, if there appears doubt, I provide more. Once there is no absolute center, a simple translation in space and time gives, of course, another set of preferred coordinates, or another absolute frame. And it is completely meaningful to recognize that an absolute frame will be also a relative frame relative to everything what is at absolute rest. This is how theories with absolute space are defined. Take Newtonian theory as an example. Who has the burden of proof depends always on the particular situation. If somebody makes a claim "it is not!", he creates such a burden for himself by this claim. The axioms of my ether theory are in no way hidden, but written down and published, in a peer-reviewed journal BTW.
