Hmm, one can predict the dynamics of galaxies only by the distribution of baryons... 

Is there a fundamental acceleration scale in the gravitational systems?  Then, there should be a transition regime...

Is the Universe indeed expanding, or it this just one interpretation of the data? If so, why its rate of stretching is unclear? 

Can a gigantic Void be responsible for the apparent accelerating behavior?

Are there alternatives of the current standard paradigm of the Big-Bang Cosmology? Can the light be tired?

The most controversial work of mine (until the next one).

The relevance of the cosmic microwave background for cosmology

If you are reading this, you will be excited to know that the most well-established observational fact in Cosmology, the Cosmic Microwave Background radiation (CMB) might actually be ... Elliptical Galaxies at z = 18.

An alternative cosmological scenario:
