Radiocarbon dating or simply carbon dating is a radiometric dating technique that uses the decay of carbon 14C to estimate the age of organic materialssuch as wood and leather, up to about 58, to 62, years Before Present BP, present defined as CE Carbon dating was presented to the world by Willard Libby infor which he was awarded the Nobel Prize in Chemistry. When an organism dies, it contains the standard ratio of 14C to 12Cbut as the 14C decays with no possibility of replenishment, the proportion of carbon 14 decreases at a known constant rate.

Carbon dating is a technique used to determine the approximate age of once-living materials. It is based on the decay rate of the radioactive carbon isotope 14 C, a form of carbon taken in by all living organisms while they are alive. Before the twentieth century, determining the age of ancient fossils or artifacts was considered the job of paleontologists or paleontologists, not nuclear physicists.

We know that carbon 14 dating is totally irrelevant to the theory of evolution. Ignorant evolutionists, however, think carbon 14 dating proves evolution, and continue to make that claim. Comedian Lewis Black, who by no stretch of the imagination is a knowledgeable evolutionist, argues.

When news is announced on the discovery of an archaeological find, we often hear about how the age of the sample was determined using radiocarbon dating, otherwise simply known as carbon dating. Deemed the gold standard of archaeology, the method was developed in the late s and is based on the idea that radiocarbon carbon 14 is being constantly created in the atmosphere by cosmic rays which then combine with atmospheric oxygen to form CO2, which is then incorporated into plants during photosynthesis. When the plant or animal that consumed the foliage dies, it stops exchanging carbon with the environment and from there on in it is simply a case of measuring how much carbon 14 has been emitted, giving its age.

Seventy years ago, American chemist Willard Libby devised an ingenious method for dating organic materials. His technique, known as carbon dating, revolutionized the field of archaeology. Now researchers could accurately calculate the age of any object made of organic materials by observing how much of a certain form of carbon remained, and then calculating backwards to determine when the plant or animal that the material came from had died.

Radiocarbon dating—also known as carbon dating—is a technique used by archaeologists and historians to determine the age of organic material. It can theoretically be used to date anything that was alive any time during the last 60, years or so, including charcoal from ancient fires, wood used in construction or tools, cloth, bones, seeds, and leather. It cannot be applied to inorganic material such as stone tools or ceramic pottery.
