True. The light has been traveling for "only" 13.7 billion years, but meanwhile the space between origin & destination kept expanding. That's why I wrote about an apparent radius, but on further thought I no longer believe that the travel time will reflect in an apparent distance. It's the amount of redshift that will result in a calculated proper distance.
