It depends upon the radioactive decay of carbon-14 14C , an unstable isotope of carbon which is continually synthesized in the upper atmosphere by cosmic rays. Plants take up atmospheric 14C for as long as they live, through the process of photosynthesis. Animals take up atmospheric 14C indirectly, by eating plants or by eating other animals that eat plants. Measuring the proportion of 14C as opposed to 12C remaining in a sample then tells us how long ago the sample stopped taking up 14C — in other words, how long ago the thing died. Carbon dating has a certain margin of error, usually depending on the age and material of the sample used. [PUNIQGOOGLESNIPMIX-1

Without understanding the mechanics of it, we put our blind faith in the words of scientists, who assure us that carbon dating is a reliable method of determining the ages of almost everything around us. However, a little more knowledge about the exact ins and outs of carbon dating reveals that perhaps it is not quite as fool-proof a process as we may have been led to believe. What is Carbon Dating?
