A commonly referenced piece of "evidence" for a young Universe is the so called "winding dilemma" of spiral galaxies. Here is the link for the ICR article authored by Russell Humphreys where it figures prominently. This article was authored in 2005.
http://www.icr.org/article/1842/
Below I have quoted the references that Humphreys is basing his critique upon. The first is a textbook that describes "density wave" theory circa 1987. And for the evidence that the theory is somehow useless we have a well known (in astrophysical and evidently creationist circles anyway) paper by Zaritsky et al. from 1993 on the observations of the central regions of M51.
1987 for the textbook
1993 for the M51 paper
2005 for the Humphreys PRATT (Points refuted A Thousand Times) list.
Now my purpose here is not to discuss the density wave theory, alternatives, successful predictions or current problems but to show what passes for "research" and the intellectual scam Humphreys and his ilk are performing. As far as I can tell - even though this argument appears again and again in the Creationist literature the above two references are the only ones typically cited and in fact the Zaritsky M51 paper is the only reference they ever use for showing problems with theory on this topic.
So what we have is really a throw the baby out with the bathwater attempt based upon a 12 (now 14) year old reference (which by the way is being taken somewhat out of context.)
If Humphreys was really interested in researching this topic and highlighting problems why only one decade + old reference? If this theory is really so weak and the evidence for the winding dilemma so strong then he can only find a single quibble. Why is there no evidence that Humphreys got off his rear end and actually looked into this subject? Yet this argument appears time and time again in Creationist PRATT lists and AIG/ICR output?
Here for comparison is a modern research paper on spiral arms as density waves:
http://arxiv.org/PS_cache/astro-ph/pdf/0511/0511037v1.pdf
And below I quote the reference list in this paper. Notice the BIG difference (besides the fact these guys actually know what they are doing and Humprheys does not) - look at the dates on the references. Think the authors might be a tad more familiar with the subject area? Think they might have done more work than ICR on this? Think they may be more honest?????????
To me this just highlights the difference between real research and the scams ICR and the like perform. One obviously references and builds upon extensive work from credible researchers over several decades and especially using up to date efforts whereas the other is a biased and scanty book report that cherry picks one reference and uses it out of context so as to paint a negative picture that is far from reality.
ICR and AIG are performing an intellectual scam so as to convince lay people that their delusional view of the universe is correct. The fact they are making their livings of this doesn't hurt either. Send out a message the brethren want to hear, facts be damned, and the donations shall keep on rolling in. That makes it far more than just an intellectual scam - it promotes it to a full blown con job.
I think the technical term to summarise the whole shebang is "Lying for Christ".

And for the evidence that the theory is somehow useless we have a well known (in astrophysical and evidently creationist circles anyway) paper by Zaritsky et al. from 1993 on the observations of the central regions of M51.
Notice the 3 dates so far:

- D. Zaritsky, H-W. Rix, and M. Rieke, Inner spiral structure of the galaxy M51, Nature 364:313-315 (July 22, 1993).
