It is the commom theory that the expanding universe explains a red shift as we perceive it! What test would you use to display a red shift in a collapsing universe that would explain it as a possibility by what we observe?

It would be a blue shift in a collapsing universe.

His question is a little unclear, but one thing is certain, there would be no red shift in a collapsing universe.

@Tes yeux noirs,
at the end of the visible universe, recently seen by the 8 meter vibration and spectrally corrected catadioptric reflector onMt Ptrzebhyeh, theyve discovered the first glimmerings of blue shifted stars . These stars and (presumably) galaxies are at about 11.65 B(c) yr away.
I assume that means something that we may not like.

It is entirely possible that there could be a collapsing cosmos, in which one or more items were moving away from an observer at sufficient speed to be red-shifted. I would think, however, that it would only be purposive movement.
