Dear Jochen,
Thanks for the thoughtful response to my assumption (speculation). Uncertain answers are common in this competition.
Does this make sense to me?
Yes, that makes sense. Although I don't have an opinion on that because I don't have enough input, so I wouldn't speculate further. What I have an opinion on, I expressed mathematically with formulas that give 100 times better results than the CODATA recommended values.
Regarding your essay, let me make a comparison with Gordian knot. No observers, no dimensions, no shapes - no problem. No Gordian knot, no problem. R=10 exp( i * pi ).
Regards,
Branko
