The intention of this thread is to see what BAUT members consider to be the strongest (ATM) alternative(s) these theories, from a quite specific perspective - ability to match several sets of good observational results.

The observations that are within the scope of this thread are the following:

1) observations of the CMB, particularly those from WMAP, but also from the observations of the CMB such as summarised here.

2) observations underlying the Hubble relationship, especially wrt galaxies.

3) observations of the abundance of elements and nuclides.

4) observations that were used to determine the large scale structure of the universe, such as those referenced here.

5) observations that the night sky is dark - that the upper limits on diffuse background EM radiation, in all bands is {X} (the CMB excepted, of course).

I am stressing observations, not interpretations. For example, in an alternative cosmology, the CMB may not have a distant origin, or the observed redshifts for galaxies, in the Hubble relationship, may arise from quite different mechanisms.

Once again, this thread is NOT about how well, or how poorly, any BB theory does, or does not, match the five sets of observations. This thread is about which alternative cosmological theory fits these observations best.

While speculation is interesting (e.g. "I reckon that {Y} theory can account for all the data very well, but I've neither read any papers showing the match, nor done any work myself to check"), I am really interested only in demonstrable matches.
Why not research this yourself and write a paper on the alternatives, or invite the authors of alternative cosmologies (Eric Lerner has contributed to BAUT) to explain their cosmological models here. You don't seriously believe that people without the proper background are able to produce an alternative cosmology?

Be prepared or?

I think that alternatives must be considered, but your list of "observations" is not a list of true observations, every single one (with the exception of the "dark sky at night") is an interpretation already. Allowing intrinsic redshifts is a very simple alternative interpretation that would possibly lead to a completely different list of "observations".
