You have provided no observations or reports of that scenario. Until then it is a mere thought experiment no better than mine.
Why didn't you say that in the first place?
I, for one, could make no connection between the two until now, and genuinely thought yours so unrelated to theirs that there was no connection between them. I genuinely thought you were throwing a random argument into the thread.
You have to tell everyone reading this what's going on in your head, not have them guess at it...
So ... all RE has to do is find a few sets of two observers at antipodal points and have them film or video sunrise and sunset with some verifiable proof of time and date in frame? Shouldn't be difficult. What will happen then? Will you assert that the T&D could have been falsified, or will you accept that the observers are simply showing you what's happening in front of them?
As for your thought experiment, I invite you to make preparations for, or commence when ready.
