This has caused many in the church to reevaluate the biblical creation account, specifically the meaning of the word “day” in Genesis 1.
Libby cleverly realized that carbon-14 in the atmosphere would find its way into living matter, which would thus be tagged with the radioactive isotope.
Dr Christine Prior is Team Leader of the Rafter Radiocarbon Laboratory at GNS Science.
In this video, she compares conventional and accelerator mass spectrometry (AMS) radiocarbon dating.
But what's interesting is that a small fraction of carbon-14 forms, and then this carbon-14 can then also combine with oxygen to form carbon dioxide.
And carbon-14 is constantly doing this decay thing. So over the course of 5,730 years, roughly half of them will have decayed. Well, if you know that all living things have a certain proportion of carbon-14 in their tissue, as kind of part of what makes them up, and then if you were to find some bone-- let's just say find some bone right here that you dig it up on some type of archaeology dig.Known as radiocarbon dating, this method provides objective age estimates for carbon-based objects that originated from living organisms.
