What I argue is in reference to the first reason this was brought up - which is it's connection to ID and the argument that ID is every bit as scientific as the Big Bang -- in fact ID has even MORE CONFIRMED science behind it than the big bang (EM wave forms showing ID for example).
I then go to the heart of the "predictive" nature of the Big Bang argument showing that the CMB is itself NOT a triumph for the science of Big Bang since the ACTUAL predictions CONFIRMED as matching the ACTUAL measurements were non-Big Bang predictions!....
Because of the obvious. Every presentation on the subject of the Big Bang known to mankind ALWAYS refers to the experiment of Penzias and Wilson as CONFIRMING the Big Ping for finding the CMB as "predicted".
YET they did not "predict" the isotrophic nature of the CMB and they did not "predict" the temperature -- in fact there WAS A PREDICTED temperature that MATCHEd -- and that is being "conveniently ignored".
So -- not as "good science" in terms of politics and objectivity as one might have hoped for.
HOWEVER - as I stated above - I am equally as happy with the "God said and it was" form of the Big Bang story as I am with ID ...
Neither of them gets to a complete YEC stage - but they both contribute to key points.
Recall that "Big Bang" was "increasingly refined from 5K to 50K"
It is rather the case, surely, that increasingly refined and more reliable measurements of the CMB support the validity of the theory,
Because they "hone in" on the NON-Big Bang estimates so perfectly?
That 'non-Big Bang predictions' of the background temperature of the Universe were more (or less) accurate than 'Big Bang predictions' is wholly irrelevant as to whether or not the CMB is a triumph for any sort of science at all.
That is almost a "religious" statement.
SCIENCE would say "IF theory-A PREDICTS this value and theory-B does NOT -- then this is NOT a AFFIRMING point for B".
You argue "all news is good news for theory-B".
As I said -- you have framed it as more of a religious argument.
Despite their strong words of affirmation declaring to the world that they now had “proof,†Big Bang supporters have had to admit that their theories about the CMB radiation are not really as concrete as they would like us to believe. Karen Fox confessed: “This radiation in and of itself doesn’t require the big bang theory per se be correct†(2002, p. 134). Fox, Karen (2002), The Big Bang Theoryâ€â€What It Is, Where It Came from, and Why It Works (New York: John Wiley & Sons).
Hoyle, et al., were a little more blunt: “...[T]he existence of the microwave radiation does not necessarily have anything to do with a big bang†(2000, p. 313). Hoyle, Fred, Geoffrey Burbidge, and Jayant V. Narlikar (2000), A Different Approach to Cosmology (Cambridge, England: Cambridge University Press).
In fact, while the Big Bang Theory predicts that cosmic background radiation should exist, it does not necessarily predict that it should exist in thermal equilibrium. As Berlinski went on to note: “Although Big Bang cosmology does predict that the universe should be bathed in a milky film of radiation, it makes no predictions about the uniformity of its temperature†(1998, p. 30). Berlinski, David (1998), “Was There a Big Bang?,†Commentary, pp. 28-38, February.

[quote:3de04]Although there were several previous estimates of the temperature of space...., these suffered from two flaws. First, they were measurements of the effective temperature of space, and did not suggest that space was filled with a thermal Planck spectrum; second, they are dependent on our special place at the edge of the Milky Way galaxy and did not suggest the radiation is isotropic. Moreover, they would yield very different predictions if Earth happened to be located elsewhere in the universe.
Your argument is that when "observations" fit another theory-A rather than B -- the story telling behind B needs to be adjusted so that it is still true - and it fits with observations as does A.
Again - one begins to wonder what kind of theory "could not survive" a continual morphing against the background of repeated failures to predict.
Having said that -- I find ID to be "better science" by far (in comparison) and I still find many things inthe Big Bang story to fit the Big-Bang Bible story.
