It takes a certain amount of time for half the atoms in a sample to decay.
It then takes the same amount of time for half the remaining radioactive atoms to decay, and the same amount of time for half of those remaining radioactive atoms to decay, and so on. The amount of time it takes for one-half of a sample to decay is called the half-life of the isotope, and it’s given the symbol: It’s important to realize that the half-life decay of radioactive isotopes is not linear.
Carbon-14 is produced in the upper atmosphere when cosmic rays bombard nitrogen atoms.
The ensuing atomic interactions create a steady supply of c14 that rapidly diffuses throughout the atmosphere.
Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering—the reason Jesus came into the world (See Six Days? He said, This only makes sense with a time-line beginning with the creation week thousands of years ago.
In the following section we are going to go more in-depth about carbon dating in order to help you get a better understanding of how it works.
Radiocarbon dating is a method of estimating the age of organic material.
Libby, a Professor of Chemistry at the University of Chicago, predicted that a radioactive isotope of carbon, known as carbon-14, would be found to occur in nature.
Working with several collaboraters, Libby established the natural occurrence of radiocarbon by detecting its radioactivity in methane from the Baltimore sewer.
