Not wanting to belive the acceleration universe model

[turbo]

Again, you're mixing up proper motion and velocity. Proper motion refers to an angular motion on the sky and it's always orthogonal to an object's redshift. Nevertheless, dark matter was not invoked to explain this particular paradox, nor is it needed to resolve it, so it's just a red herring.

I apologize for the imprecise terminology, but there are hundreds, more likely thousands of papers out there written about clusters that invoke dark matter to supply the gravitational attraction need to bind clusters and keep them together. The standard model absolutely needs DM in clusters to hold them together. Indeed, many large-scale searches for DM have been modeled using cluster geometry as tracers of DM distribution. If there is a model that can explain the Fingers of God effect without invoking intrinsic redshift and without the need for DM to help bind the clusters so they don't fly apart, can you point me to the paper(s)?
