Is the Romance of Radiometric Dating Getting Old?

Radiometric dating is still a faulty argument against biblical history. Naturalistic geolo­gists often “cherry-pick” dates they deem appropriate to their particular studies. Carbon-14 has been found in coal and diamond samples supposedly be billions of years old, even though the half-life of 14C is only 5730 years. The creationist RATE group's theory that there have been periods of accelerated nuclear decay in the past runs into the problem of rapid volume cooling. Woodmorappe's statistical noise theory that radiometric dating is inherently unreliable may indeed be vindicated.

The inherent inconsis­tency of secular results strengthens the argument for a young earth, as the Bible describes in a most straightforward way!

Introduction

Radiometric dating remains a popular, but still faulty, argument against biblical history.
Radiometric dating utilizes the decay rates of certain radioactive atoms to date rocks or artifacts. Uniformitarian geologists consider this form of dating strong evidence that the Earth is billions of years old. Many atoms (or elements) exist as numerous varieties called isotopes, some of which are radioactive, meaning they decay over time by losing particles. Radiometric dating is based on the decay rate of these isotopes into stable nonradioactive isotopes. To date an object, scientists measure the quantity of parent and daughter isotope in a sample, and use the atomic decay rate to determine its possible age. (Creationwiki, 2012)
But research by creationists has revealed a large number of problems with radiometric dating. 

For instance, Naturalistic geolo­gists often “cherry-pick” dates they deem appropriate to their particular studies, and if results do not agree with expected dates, the “error” is attributed to any number of possible problems (Froede, 2010).

Yet another challenge for the interpretation of nuclear decay findings is documentation of detectible Carbon-14 in coal and diamond samples purported to be billions of years old, even though the half-life of 14C is only 5730 years.

Radiometric Age-Dating in Creation Science— A Brief History

Beginning with the publication of The Genesis Flood (Whitcomb and Mor­ris, 1961), radiometric age-dating was deemed incompatible with biblical history. Over the years, many young-earth creationists have documented the problems and unbiblical assumptions of various dating methods (Acrey, 1965; Armstrong, 1966; Clementson, 1970; Cook, 1968; Lammerts, 1964; Whitelaw 1968, 1969a, 1969b; Woodmorappe, 1979, 1999).

However, many young-earth creationists have suggested that radiometric dating can be accepted with one or more episodes of ac­celerated nuclear decay having occurred during Earth’s past.

In 1968, Gentry proposed a bold idea based on his work on radioactively damaged zircons. He stated, “While there might be other alternatives, one possible explanation of these ‘fractures’ or ‘blasting’ halos is that the rate of ra­dioactive decay was at one time greater than that observed today” (Gentry, 1968, p. 85; italics added).

But no one could of­fer a mechanism for decay acceleration.

Chaffin (2000) proposed that a variation in the fifth dimension of our universe early in the Creation Week might have led to accelerated nuclear decay.

RATE Project

As a joint project between the Institute for Creation Research and the Creation Research Society, the RATE group convened in 1997 to discuss issues with radiometric dating within the framework of a young earth  (Vardiman, 2000).

Research seemed predicated on the belief that
at some time in the past much higher rates of radioisotope decay may have occurred, leading to the production of large quantities of daughter prod­ucts in a short period of time. It has been suggested that these increased decay rates may have been part of the rock-forming process on the early earth and/or one of the results of God’s judgment upon man follow­ing the Creation, that is, the Curse or during the Flood (Vardiman, 2000, p. 4).
The results of the eight-year study were published in 2005 (Vardiman et al, 2005), and the RATE scientists de­termined that "accelerated nuclear decay was the most promising explanation for the large amount of daughter products." (Vardiman, 2005, p. 7).

Problem of Massive Heat Generation

Any episode of rapid nuclear decay should result in the release of large amounts of heat (Humphreys, 2005; Snelling, 2005; Vardiman, 2005). This heat would profoundly affect the planet, whether it happened during the Cre­ation Week, following the Curse, or during the Flood. Humphreys (2005, pp. 68-70) stated
rapid cooling occurred .... most of the cooling could not be by the normal processes of conduction, convection, or radiation. Instead, the process would have to cool the entire volume of material simultaneously (“volume” cooling) and abnormally fast.  
In my feasibility study, I pointed out a little-known and less-understood phenomenon in standard General Relativity theory that seems quite relevant. The mech­anism causes photons and moving material particles in an expanding cosmos to lose energy. The equations clearly show the loss of energy but where and how the energy goes is less clear…. This mechanism offers good potential for removing heat on a large scale. 
But if volume cooling cannot be empirically demonstrated, then it remains specula­tion.

Variability in the Rates  of Nuclear Decay: K-Ar, Rb-Sr, Sm-Nd, and Pb-Pb Isochron Discordance

In his analysis of the parent/daughter radioisotopes for the Beartooth amphibolite (Wyoming) and the Bass Rapids diabase sill (Grand Canyon, Arizona), Austin determined that changing decay rates created discor­dances in the K-Ar, Rb-Sr, Sm-Nd, and Pb-Pb radioisotope age-dates. He noted,
Furthermore, our data are consistent with the possibilities that, at some time or times in the past, decay of the α-emitters (238U, 235U, and 147Sm) was accelerated more than decay of the β-emitters (87Rb and 40K). (Austin, 2005, p. 386)
Snelling and others reached this same conclusion in their investigation of the Bass Rapids diabase sill (Snelling et al, 2003, p. 283).

Both projects concluded that there was decay-dependent variability in the rate of nuclear decay that should show consistent differences between different radiometric dating methods, yet some level of consistency in the same method.

What radiometric age- dates would indicate Creation Week rocks, post-Curse antediluvian rocks, or Flood rocks and sediments? (Figure 1) If the results (using accelerated decay) are to be useful, the ability to link rocks/sedi­ments to biblical history is essential. This also raises the question of a quantifiable conversion factor for each radiometric method; such numerical factors would be invaluable for creationist analyses of radiometric age-dates (Figure 2).

Figure 1. This diagram shows a biblical geologic timescale with three shaded boxes corresponding to the three periods of time when accelerated radiomet­ric decay purportedly occurred. The darker the box, the greater the level of accelerated radiometric decay based on the findings of the RATE project team.

Figure 2. This diagram presents a hypo­thetical mathematical formula necessary to convert naturalistic radiometric dates to accelerated and acceptable values in the Creation/Flood geologic framework of earth history. Missing are the conversion factors for each of the secular radiometric age-dating methods. These factors will need to be provided in order to demonstrate that accelerated nuclear decay occurred within the anticipated time frame of the biblical record (see Figure 1).
Inconsistency between Carbon 14 and Long-Lived Nuclides

Baumgardner (2005) presented an in­teresting study on detectable carbon 14 (14C) in various “old” coal deposits and diamonds.
... during the Flood might have affected a offer the tentative hypothesis that, This amount of decay represents short half-life isotope like 14C.... perhaps only a modest amount of accelerated 14C decay took place dur­ing the cataclysm itself.... whatever the physics was describing the decay acceleration, it did not operate in so simple a manner as to reduce temporarily the effective half-lives of all radioisotopes by the same factor. (Baumgardner, 2005, p. 620)
At present, it is not clear how ac­celerated nuclear decay could have occurred at very high rates for the K-Ar, Rb-Sr, Sm-Nd, and Pb-Pb systems but at very low rates for short-lived isotopes such as 14C.

Certainty and the RATE Results

It is use­ful that some of the results of the RATE research appear to be critiques of radio­metric dating from both theoretical and experimental perspectives (Snelling et al, 2003; Snelling, 2004).

Unfortunately, the same circularity that afflicts modern secular stratigraphers seems likely to also plague creationists that take this route. Quantifying accelerated decay for each dating method would go a long way to­ ward reducing those uncertainties.

Discussion and Conclusions
The RATE group considered the possibility that a substantial amount of decay might have occurred dur­ing the Judgment in the Garden of Eden, but then it was concluded that the implied levels of radiation and heating would have been so highly destructive to biology at that point in earth history as to render this possibility unlikely (Vardiman et al, 2005, p. 737).
Unfortunately, there is an inherent problem of knowing the relative ages of rocks in the first place. Some creationists resolve this problem by accepting a compressed ver­sion of the standard geologic timescale, although one reason for doing so is the presumption of accelerated radiometric dating (Dickens and Snelling, 2008a, 2008b). However, Reed (2008a, 2008b, 2008c, 2008d) and others (Froede, 2008; Reed and Oard, 2008) have questioned this approach.

There is a demonstrated lack of accuracy and precision of radiometric results, and their inconsistency with other field evidence. Some of these stud­ies showed results that were definitively wrong (Austin, 1988, 1992, 1994, 1996, 2000; Snelling, 1995, 1999a, 1999b, 2000a, 2000b).

The statistical noise theory was a competing model proposed by Woodmorappe (1999). He asserted that radiometric dating is inherently unreliable and that secular scientists select desired results from a reservoir of inconsistent results, based on their needs at the time. It would require researchers to find a quantitative basis for eliciting consistency from apparently inconsistent results. This might provide the basis for conversion factors or equa­tions that would ultimately allow the theory to become useful in field studies. If they cannot, then the skepticism of Woodmorappe (1999) and the earlier creationists who wrote against radiomet­ric age-dating might be vindicated.

But even then, a good result will have been achieved. If creationists can demonstrate the inherent inconsis­tency of secular results, the argument for a young earth is greatly strengthened. This would force acknowledgment that chronology must ultimately rest on the divinely inspired historical documents provided in the Bible. Similarly, the demonstration of the unreliability of radiometric dating would reinforce the inherent weakness of the geological timescale (Reed, 2008c).
