Red shift of light reflected from universe boundary

[asimations]

tif we presume that our finite universe has a boundary. This boundary is due to the pull of gravity. Light will slow down and then come back to us. 'i may be absolutely wrong in this'. My question is that the light we see will be from the stars surface that doesn't face us and star moving away from us as it hasnt reached the boundary yet. What will be the red shift value of this light.

There is no boundary!

The universe has no edge or "center".

 

[asimations]

i guess it has event horizon that is like an edge

This is turning into speculation piling on more speculation.
