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!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.Radiocarbon Basics Carbon comes in three “varieties” or isotopes: C is 5,730 years.Because carbon is expected to be thoroughly mixed throughout the biosphere, atmosphere, and oceans, living organisms (which continually “take in” carbon throughout their lifetimes) are expected to have the same C in their bodies begins to decrease.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!
Evolutionists have long used the carbon-14, or radiocarbon, dating technique as a “hammer” to bludgeon Bible-believing Christians.
A straightforward reading of the Bible describes a 6,000-year-old universe, and because some carbon-14 (C) age estimates are multiple tens of thousands of years, many think that the radiocarbon method has soundly refuted the Bible’s historical accuracy.
