I don’t know the answer right now. I will look into it some more when my brain is working better. Because I do now recall that it is not as straight forward as it might seem at first.

For example...

3.1 Redshift velocity and recessional velocity
3.1.1 Redshift velocity
3.1.2 Recessional velocity
3.2 Observability of parameters
3.3 Expansion velocity vs relative velocity
3.4 Idealized Hubble’s Law
3.5 Ultimate fate and age of the universe
3.6 Olbers’ paradox
3.7 Dimensionless Hubble parameter

No, there’s nothing straightforward about it at all. It’s a real mind bender.

The light from EGS-zs8-1 that we see now has traveled a more or less straight line from where it was 13 billion years ago to where we are now. So when we look at that from here we are seeing its position, from here, 13b years ago.

But EGS-zs8-1 has had 13 billion years to move from that position just as the Milky Way had 13 billion years to move from where it was then to where we are now.

Or so it would seem to me.
