Akinbo,
The interstellar 'wind' (frame) direction change is only predicted by the DFM's cyclic model, caused by the peculiar motions of the ISM and the stars slow rotation around the local arm (see the ref's in that paper).
I was filing away the paper above and came across this, identifying the ('Sun's) direction change. (of 4-9 degrees wrt the local surrounding 'ambient medium' or 'cloud' rest frame ).
(The link I posted from the findings of the new multi billion VLBA telescope array proves the refractive scattering to the 'cloud frame).
But far wider than that, checking out the latest particle physics papers is even more conclusive. I've just posted the links on "Ripping apart..." where they point the way to coherently re-assembly of the genuine remnants of both Einstein and Newton!
Now don't fret. No matter what the evidence I know you'll believe whatever you wish to as we're all only human, but I do thank you for causing me to to the quick trawl which found those important confirmations of the new coherent shape of the puzzle pieces. If you'd like a more theoretic view of the same logic the 2013 'Paper of the Year' from SISSA's Liberati points from another vector 'triangulating' the logical solution into a tightly constrained 'DFM like' dynamic;
Tests of Lorentz invariance: a 2013 update.
