From the photon's own POV, there is no expanding space. It doesn't even move. The distance between the point of emission and point of absorption is zero
I'm interested in this statement being fleshed out more. Are you meaning because time would not seem to pass and so there is no motion, or that its behavior is "wormhole" like?
It seems intuitive to me that if space is expanding that would have to mean something for photon, some change in how it behaves.
In fact that raises a question in my mind of if there are any possible (intriguing) consequences for speed of light being fixed in a universe that is expanding (or accelerating)?
I know these are more dumb questions... but that's why I need to ask them.
