Mythology of modern dating methods
Upon being presented with claims that radiometric dating is totally erroneous, a question naturally arises: If radiometric geochronology is half as bad as Woodmorappe's list suggests, then how in the world did geologists ever arrive at a tight consensus for the official dates?
Look at the various radiometric tables in use over the last 20 years or so and you will find, at least for the fossil-bearing strata, a remarkably tight agreement. Did the geochronologists throw darts to determine the accepted dates?
Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.
One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.
Baumgardner) have formed the RATE (Radioisotopes and the Age of The Earth) committee to attack the validity of radiometric dating.They are now relying on nuclear physics, e.g., Chaffin, 2003 (Adobe Acrobat file) and probably an ample supply of groundless miracles to speed up the decay rates without frying Adam or Noah. (2003) (Adobe Acrobat file), although full of errors and bad assumptions, also makes the following candid admission (p. Snelling, 2003, "Helium Diffusion Rates Support Accelerated Nuclear Decay", Proceedings of the Fifth International Conference on Creationism, R.3), which is a veiled attack on Woodmorappe's "crapshoot" and similar YEC schemes that involve bogus accusations against radiometric dating methods and equipment: Samples 1 through 3 had helium retentions of 58, 27 and 17 percent. Ivey (ed.), Creation Science Fellowship, Pittsburgh, PA.(Matson, 1993, p.1) Either we have a worldwide conspiracy among geologists, which no sane person believes, or else the numerous radiometric dates were consistent enough to allow that kind of close agreement. Dalrymple, an expert in radiometric dating with lots of hands-on experience, puts the percentage of bad dates at only 5-10 percent.Thus, we clear away the first illusion spun by creationism, namely that most of the dates are bad, that the radiometric picture is totally chaotic.
