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?Yet a skeptic might point out that the amounts of C found in these organic samples are smaller than what one might expect if they are only about 4,500 years old.
From Figure 1, a value of 0.098 ≈ 0.1 p MC corresponds to 10 half-lives, or about 57,000 years.
Are these high radiocarbon “ages” a problem for the biblical worldview? First, remember that no detectable should be present within these samples if they really are millions of years old.
One can estimate this time by dividing 100 p MC by 2 repeatedly until the resulting number drops below 0.001 p MC.
We find that about 18 such halvings are required for the p MC value to drop below 0.001 (Figures 1 and 2).
We have a number of resources ranging from video discussions with our scientists, virtual tours through google hangouts to live streaming of our public lecture series called Argonne Outloud.
