I have been arguing the case that the universe may be a modified Milne model. Let me ask my questions first. First, I am asking about graphs and data presented here: http://www.astro.ucla.edu/~wright/sne_cosmology.html Questions 1) The "binned data" appear to be points with constant redshift (y-axis), but with error-bars in the luminosity distance. (x-axis). How many supernovae make up each of the "bins." Better yet, is there a similar graph that simply shows one dot per data-point? 2) The remaining graphs on the page all refer to [itex]\DELTA D M[/itex]. What is this quantity? 3) I believe this data appear http://arxiv.org/abs/0804.4142" [Broken]. Is there a copy of this data anywhere in spreadsheet format? 4) Also, what are z, m(max B), s, c, mu? Are these sufficient to find Right Ascension, Declination, Luminosity Distance, and Redshift? Now, if you're curious about the modified Milne model: In the Milne model, all of the universe explodes from a single event. A fixed "point" in space is stationary in only one reference frame. On the other hand, a fixed event can be the center of an expanding sphere in any and every reference frame. The particles in the Milne universe are least dense in the center, and much more dense on the outside. Any observer in the Milne universe will be co-moving (but not necessarily co-located) with the center, in his own reference frame. There is some argument that the Milne model can only represent an empty universe. I acknowledge that I have never understood this argument. Milne's own analysis was that there had to be an infinite amount of matter in the causally connected portion of the universe. The density of particles increases towards infinity at the outside edges. The reason I wish to modify the Milne model is to add two or three major events. These events are sudden accelerations of our galaxy or explosions of the matter around our galaxy, while the universe was still very dense, well before our galaxy actually spread out into stars. I found that an http://groups.google.com/group/sci.astro/msg/2751e0dc068c725c?hl=en" in the supernova data seemed consistent with this modified Milne Model.
