Akinbo,
Newton's error emerges by splashing his bucket with water as it spins. If the drops fall off vertically he's correct, if they're thrown outwards the DFM is correct. Once the bucket and water within it spin in unison they are in the same frame and the 'background' to the contents becomes the same as for the bucket; It's the carriage of the train you're doing the experiment in.
Whether or not the train is moving (rectilearly) or the planet you're on is spinning, or orbiting, etc, is entirely irrelevant to the bucket and it's LOCAL BACKGROUND. Only the LOCAL background is ever valid for determining propagation speed. Neither Newton or SR were then complete. The DFM simply completes both them and QM. We now know the galaxy spins "in lockstep" (SciAm editors words not mine), so not as individual bodies but as a 'dinner plate' complete with the local halo and Interstellar Medium (ISM) rest frame through and wrt which light propagates locally at c. Thus the red and blue shifts.
Of course there's a centre of (finite) universe rest frame, but that has no validity as a basis to the LOCAL propagation speed of WEM fluctuations. That's exactly the same as sound. 'Speed' is only a local and relative concept.
I understand your view on increments. I tried that for many years and it didn't work. People just invoke current peripheral beliefs to dismiss the most solid evidence and logic. For each one knocked down 3 others pop up if no fundamental rationale stops them! An ontology can only defeat myth as an ontology. I agree it's too much of a step for most to countenance in our current state of intellectual evolution but it is what it is.
Your view that it's "too ambitious a project" identifies the comprehension gap. many realise that when we DO 'crack the code' of what's really going on, then the consistent physics will all flood out. That's what's happened. I'm not "trying to do" anything! - 'seeking truth' is the task any more, I'm landed with the task of 'explaining it' so just have to find the best way.
I am indeed overwhelmed by the coherent resolutions flooding out. I feel like the boy with his finger in the dyke. Nobody took any notice so I had to let some out, now it's a gaping hole and uncontrollable flood! Many will 'drown' if the fundamental rationale isn't understood.
Most of the papers do still only deal with small aspects. The 'master' paper is only being developed slowly, waiting for the right time and 'approach' once I find it. All the eminent's were right; A "new way of thinking" about the universe is needed. To me rationalising 'thinking' is a far trickier task then rationalising nature! I thought you were grasping it a few times, but slipped back to other assumptions. But there's no panic. I hope it's inevitable, if we survive our currently fatal stupidities!
Best wishes
Peter
