When today’s rates are used to calculate ages from certain radioisotope ratios, the results indicate that billions of years’ worth of nuclear decay of the heavier radioisotopes has occurred.But there is evidence that this decay occurred in accelerated “spurts,” Why the High Radiocarbon Age Estimates?If the scientist did not realize that the pre-Flood C/C ratio was hundreds of times smaller than today’s value, he would calculate the animal’s age to be approximately 9 × 5,730 years = 51,570 years old—even though it had just died!Of course, he would realize that this age was nonsense, because he saw the fresh carcass.Because the present decay rates of these heavier isotopes are so small, the assumption that these rates have always been constant naturally leads to age estimates of millions and even billions of years.Interestingly, however, some radioisotope methods tend to consistently yield younger age estimates than others, even when the techniques are used on the same rock units.Could this be a clue that radioisotope “clocks” might have “ticked” at different rates in the past, and that this variation in “ticking” is different for different radioisotopes?

Despite this apparent difficulty for the recent-creation view, this is, in fact, a much more serious problem for the old-earth view!

And a radiocarbon result that contradicts old-earth dogma is not a good enough reason by itself to invoke contamination!

Assumptions…Assumptions Instead of arbitrarily blaming these anomalous results on contamination, a far better (and more scientific) approach would be to question the correctness of the assumptions behind radioisotope dating methods.

We find that about 18 such halvings are required for the p MC value to drop below 0.001 (Figures 1 and 2).

(We could “round up” the value of 0.0007 p MC at 17 half-lives to 0.001 p MC, but the 0.00038 p MC at 18 half-lives is definitely below the detection threshold.) Since each half-life is 5,730 years, this means that no C has even been detected in diamonds, which some scientists claim are billions of years old!Second, such large calculated ages are based on the C/C ratio has remained unchanged for tens of thousands of years.
