See the thread on Curvature Cosmology for a possible alternative. Regards David

My main argument about dark matter is that nearly all arguments for it rely on the virial theorem which computes the mass from velocity dispersion. However it explicitly requires that the velocities used are actual velocities. I argue that the observed redshifts can be corrupted by curvature...

Please read the chapter on supernovae which refutes the standard analysis.

As I have explained in my book I don't believe in black holes. I fully support General Relativity but I argue that curvature pressure not only prevents the ultimate collapse but can produce the jets that are seen in quasars etc.

I consider curvature cosmology to be a first order theory in that the universe is static and time is unbounded. Whether or not there is a beginning or end to time requires a deeper and more profound theory.

In curvature cosmology the cosmic background radiation has a completely different origin. Hence the conclusions drawn from WMAP about flat spacetime, etc. are not relevant.

This is a very speculative hypothesis and rather than give a brief glib statement I would rather you to chapter 4 in the book. Don't hesititate to call me if you find any inconsistencies or bad arguments.

This topic is covered (I hope fully) in the book. I believe that the standard argument about increase in entropy is flawed when applied to the universe. All the elements are continually recycled. The very high temperature inter-galactic plasma breaks down heavier elements into lighter ones.

Yes it does. Please see Chapter 6 Regards David

Curvature Cosmology is a cosmology based on two hypotheses. The first, curvature redshift, is an interaction between photons and curved spacetime and produces the observed Hubble redshift. It can also explain the anomalous Pioneer 10 acceleration. The second, curvature pressure, is a...
