What a pile of baloney and an intellectually lazy argument. The dating theories are dubious for lots of reasons that have nothing to do with current decay rates. For example, two unprovable assumptions of all dating methodologies based on radioactive decay are:Quote:
Well...except they are not really dubious. If the science behind them wasn't generally accurate, then our formulas for radioactive decay would not be accurate and we'd have likely created a horrible tragedy via our early testing of nuclear weapons.
1) That the decay rates have remained constant across millions, even billions, of years; and
2) That the element the decay rate of which is being measured started off with 100% of it being the parent (is that the correct term?) isotope or element.
Neither of those assumptions have any bearing whatsoever on testing of nuclear weapons.
And we know that those assumptions are wrong with C14 dating, the only radioisotope dating mechanism we can actually test. C14 scholars recognize that its decay rates have varied over time and that the starting point for the C14/C12 ratios varied due to a variety of factors, such as proximity to upwelling of "old water" that's free of C14 in the easter Mediterranean or possibly proximity to sources of gas release, gas that's comprised primarily of C12, not C14.
Here's an example of a paper written to address those issues with regard to C14 dates:
