Re: Question,
Response 1. Is a red herring. The method of dating isn't in question. The fact that airplanes 50 years ago would date to millions of years is the question.

Is your typo intentional or accidental? Your article reference said "thousands", not "millions" (we don't have ice core sequences in the millions of years).

But your creationwiki article gives no evidence even of thousands. It talks about thicknesses, and implies that this must equate to thousands of years. The thickness of these layers gets thinner and thinner as one goes down due to the increasing pressure.

I think your YEC article is making an unwarranted uniformitarian assumption that the relation of ice thickness to time span is constant. It is not.

uniformitarianism has been verified? Stop the presses! I'd like to see the article on that. You really like saying science. It's like your religious mantra. Because if SCIENCE says it! What science? Science is your god and idol. lol

...

How does uniformitarianism not apply to this thread? We are talking about dating, so the fundemental aspect of radiometric dating is based on a religious worldview. Your religiousity scares me.

There's a LOT of confusion here.

1) "Uniformitarianism" vs "catastrophism" was a valid historical debate a century or so ago, restricted to discussions of geological processes. Uniformitarianism initially won out, but the modern picture is a combination of both. The impact event that killed the dinosaurs is an example. David Raup wrote a nice popular level book on this a few years back (Maybe The Nemesis Affair?). But this has little to do with modern dating methods. In fact, modern dating methods make the discussion moot because their dates do not depend on the rates of geological processes.
Note: the YEC application of "uniformitarianism" to all of science is just plain wrong. For most areas of science the term is irrelevant.

2) Radiocarbon was initially based on "uniformitarian" assumptions (decay rate is constant, natural abundance ratio in upper atmosphere is constant). Further research has verified the first assumption, and given minor corrections to the second. Calibrating to tree ring dates avoids these uniformitarian assumptions, BTW.

3) One's "uniformitarian philosophy" or religion does not change the facts or reliability of the dating methods.

4) Some of the early developers of radiocarbon dating were evangelical Christians. They did not treat science as their god or idol.

Edited by kbertsche, : clarified point 1.
