The lower the amount of Carbon-14, the longer it has been since death occurred.
The theoretical limit of the usefulness of Carbon-14 dating would only be 50,000 years.
When finding the age of an organic organism we need to consider the half-life of carbon 14 as well as the rate of decay, which is –0.693.
For example, say a fossil is found that has 35% carbon 14 compared to the living sample. We can use a formula for carbon 14 dating to find the answer.
The Carbon-14 dating method was introduced by Dr. Libby (1908-1980) at the University of Chicago in 1949. Carbon-12 is the normal stable isotope of Carbon (99% of all Carbon), which is the basic building block of organic life forms.
He claimed that it was capable of dating animal, plant and human remains of fairly recent origin. As they say on Star Trek, we are all carbon based units.
They want to know if it is accurate or if it works at all.
Worse still, sometimes they want to know how evolutionists use Carbon-14 to date dinosaur fossils!
The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles.Where t is the age of the fossil (or the date of death) and ln() is the natural logarithm function.If the fossil has 35% of its carbon 14 still, then we can substitute values into our equation.In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years.
This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago.
