As always, somebody will ask for a model, a diagram or anything even close to a scientific argument for the Sky mirror and the rest of the thread will be angry ranting on how we are idiots who cannot accept this wonderful idea. Then somebody will try to explain how the scientific method is the minimum one can ask for in a scientific discussion and all hell will break loose.
There has never been a single diagram to help us see that this idea is even half baked. We should not ask again and accept that the answer is: "if the diagram does not fit (or does not even exist), the idea is bogus".
