... if it can be proved that red-shifting is not due to Doppler expansion...
The Doppler Effect has been commonly accepted since just after 1842, when proposed by Christian Doppler. It seems to be the basis of a lot of science, and has been embraced by such notables as Hubble, Einstein, and Hawkin, to name a few.
State your theory as to why red-shifting is not due to the Doppler Effect, and then maybe we can discuss it.
