If a medium with a light wave moving slower in the same direction
light would be seen to back out to the medium edge... but how can
it then speed back up and then stay slow at the medium's backside?
The principle of the constancy of the speed of light is absolute.

What about right after the Big Bang, during the superluminal expansion phase?
That hypersphere radius expansion was in an instant.
There is an eternal singularity that is empty as
nothing has ever moved inside the hypersphere
and never will. Its entire future is expansion.
But it slowed from the instantaneous at the
beginning of gravity.
More distance is the future of the universe.
If galaxies grow there is "No preferred scale"
of universal expansion. CMBR has redshifted
by that same universal expansion.
God is creating gravity-time.
