I don't want to lose the main question of my original post.
So far, no-one has given me an answer to the questions of my original post. I hoped I could find someone who knew how to obtain the following data about the supernovae .
a) right ascension
c) luminosity distance
I disagree. The standard model cosmology does not have that good of a track record. One need only skim through an article about dark energy
to see that it introduces more questions than it answers.
I can't claim to understand these problems exactly. However, they simply don't arise in the Milne model.
For instance, in the Milne model, inflation
arises very naturally from acceleration. You take a sphere expanding at the speed of light, and perform a Lorentz Transformation around any event after the Big Bang.
All you need is collisions or explosions to get the necessary Delta V.
If you accelerate toward
the center, it will expand the universe. If Milne was correct, and all particles are attracted to the center, then this phenomenon would go on forever, accelerating toward a receding center would make inflation continue forever.
