I wanted to read Francis´ paper in the weekend, but I started last night and I couldn´t stop.
Extremely interesting aspects I´ve never thought of (although you, Ken G, and some other experts might say: nothing really new). And I assume I understood, say 60 to 70 %, of it. But then, when it comes to “The Expansion of Space and Redshift”:
Quote:
The key is to make it clear that cosmological redshift is not … a gradual process caused by the stretching of space a photon is travelling through. Rather cosmological redshift is caused by the photon being observed in a different frame to that which it is emitted. (my bold)
Now I´m really lost. Which doesn´t mean that I´m disappointed. On the contrary. I know that there´s something beyond my knowledge, but I feel that it seems to be “true”. I would be more happy if I understood it. Well, I´ll start to think more about redshift in the context of Francis´ paper.

Thanks again for your and Tim Thompson´s link to his paper
