i was going to post this in Gary's "breakthrough in physics" thread or has this topic been covered before ??? Anyway, I thought it deserved a thread of it's own.
Having successfully completed OU course S281 a few years ago I thought I knew a little bit about basic cosmology.
However, over on Premier Radio's discussion forum YEC poster "ploughboy" (Martin) has reminded me of this letter/ad which appeared some 5 years ago in New scientist:

| Quote | An Open Letter to the Scientific Community
Cosmology Statement.org (Published in New Scientist, May 22-28 issue, 2004, p. 20) http://www.cosmologystatement.org/
The big bang today relies on a growing number of hypothetical entities, things that we have never observed-- inflation, dark matter and dark energy are the most prominent examples. Without them, there would be a fatal contradiction between the observations made by astronomers and the predictions of the big bang theory.
In no other field of physics would this continual recourse to new hypothetical objects be accepted as a way of bridging the gap between theory and observation. It would, at the least, RAISE SERIOUS QUESTIONS ABOUT THE VALIDITY OF THE UNDERLYING THEORY.
But the big bang theory can't survive without these fudge factors. Without the hypothetical inflation field, the big bang does not predict the smooth, isotropic cosmic background radiation that is observed, because there would be no way for parts of the universe that are now more than a few degrees away in the sky to come to the same temperature and thus emit the same amount of microwave radiation.
Without some kind of dark matter, unlike any that we have observed on Earth despite 20 years of experiments, big-bang theory makes contradictory predictions for the density of matter in the universe. Inflation requires a density 20 times larger than that implied by big bang nucleosynthesis, the theory's explanation of the origin of the light elements. And without dark energy, the theory predicts that the universe is only about 8 billion years old, which is billions of years younger than the age of many stars in our galaxy.
What is more, the big bang theory can boast of no quantitative predictions that have subsequently been validated by observation. The successes claimed by the theory's supporters consist of its ability to retrospectively fit observations with a steadily increasing array of adjustable parameters, just as the old Earth-centred cosmology of Ptolemy needed layer upon layer of epicycles.
Yet the big bang is not the only framework available for understanding the history of the universe. Plasma cosmology and the steady-state model both hypothesise an evolving universe without beginning or end. These and other alternative approaches can also explain the basic phenomena of the cosmos, including the abundances of light elements, the generation of large-scale structure, the cosmic background radiation, and how the redshift of far-away galaxies increases with distance. They have even predicted new phenomena that were subsequently observed, something the big bang has failed to do.
Supporters of the big bang theory may retort that these theories do not explain every cosmological observation. But that is scarcely surprising, as their development has been severely hampered by a complete lack of funding. Indeed, such questions and alternatives cannot even now be freely discussed and examined. An open exchange of ideas is lacking in most mainstream conferences.
Whereas Richard Feynman could say that "science is the culture of doubt," in cosmology today doubt and dissent are not tolerated, and young scientists learn to remain silent if they have something negative to say about the standard big bang model. Those who doubt the big bang fear that saying so will cost them their funding.
Even observations are now interpreted through this biased filter, judged right or wrong depending on whether or not they support the big bang. So discordant data on red shifts, lithium and helium abundances, and galaxy distribution, among other topics, are ignored or ridiculed. This reflects a growing dogmatic mindset that is alien to the spirit of free scientific enquiry.
Today, virtually all financial and experimental resources in cosmology are devoted to big bang studies. Funding comes from only a few sources, and all the peer-review committees that control them are dominated by supporters of the big bang. As a result, the dominance of the big bang within the field has become self-sustaining, irrespective of the scientific validity of the theory.
Giving support only to projects within the big bang framework undermines a fundamental element of the scientific method -- the constant testing of theory against observation. Such a restriction makes unbiased discussion and research impossible. To redress this, we urge those agencies that fund work in cosmology to set aside a significant fraction of their funding for investigations into alternative theories and observational contradictions of the big bang. To avoid bias, the peer review committee that allocates such funds could be composed of astronomers and physicists from outside the field of cosmology.
Allocating funding to investigations into the big bang's validity, and its alternatives, would allow the scientific process to determine our most accurate model of the history of the universe.

I am well aware of the concepts of inflation and dark matter which were covered in S281. The BBC discusses them in an episode of Sky at night in May 2008 entitled "what we just don't know" where the guests were Dr. Chris Lintot (co presenter), Dr. Kate Land, and Professor Gerry Gilmore.:
http://www.bbc.co.uk/science/space/skyatnight/proginfo.shtml
AiG have also picked up on big bang dissenters
"A Brief History of Intolerance in Modern Cosmology"
http://www.answersingenesis.org/article....smology
I have learned that the cosmic microwave background radiation put paid to Fred Hoyle's steady state cosmology, undeniable proof of the Big Bang theory.or so I thought. I notice AiG highlight Halton Arp, who you'll notice is a signatory of the letter above and who it seems, has observed quasers with large redshifts close to normal galaxies with low redshifts. He thus concludes that redshift might not be proof the universe is expanding. He also rejects big bang cosmology and as a result has been isolated within the astronomical community. Arp is seen as a modern day Galileo in some circles.
So, a couple of questions. How well known and how respected is Halton Arp in cosmology circles ? Are his ideas seen as completely wacky or do they command a certain amount of respect ? Are they based on old observations ? Ploughboy (Martin) claims a lot of cosmologists don't support the big bang. How representitive are the signatories of the letter to New Scientist ? I suspect Martin's claim (and AiG's) are similar to the "more and more scientists are abandoning evolution" one (project Steve springs to mind of course). However, since I haven't done any cosmology for a few years (I'm thinking of having a go at the OU again) I'd like a little feed back.
