Yeah, Rosen, ol' JW had some interesting theories, didn't he?
After reading this paper, it almost seems like these folks are taking Hubble as a given and accepting that a galaxy past a certain distance must have superluminal recession, and the paper is intended to show how this superluminal recession could exist without violating SR or causing an infinite redshift. Is that how you read it?
So now I have a more general question . . . how do we determine the distance to these galaxies?
We're obviously not using Hubble the other way (using redshift to determine the velocity and determining the distance from that), and these galaxies are certainly too far away to use parallax, so how do we know they're so far away they should be superluminal?
