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.
Because these radioisotope methods yield age estimates of many millions of years for igneous rocks, it is thought that sedimentary rocks are also millions of years old, as well as the organic remains found within them.One of these assumptions is that nuclear decay rates have always been constant.Although C decays fairly quickly, heavier isotopes (such as uranium-238) decay much more slowly.Virtually all fossils found within sedimentary rocks are the remains of creatures that perished during the Genesis Flood about 4,500 years ago.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.Smallest Detectable Amount of Radiocarbon Sensitive instruments called acceleration mass spectrometers (AMS) are used to count the C/C ratio in a sample drops below 0.001 p MC?
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 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!However, these excessively long ages are easily explained within the biblical worldview, and C should be present in specimens that are even a little more than 100,000 years old!Nearly anyone can verify this for themselves using basic multiplication and division.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.
