Does Radiocarbon Dating Accuracy Help Us Determine Bible Chronology? - Biblical Archaeology Society

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. But new research conducted by Cornell University could be about to throw the field of archaeology on its head with the claim that there could be a number of inaccuracies in commonly accepted carbon dating standards. If this is true, then many of our established historical timelines are thrown into question, potentially needing a re-write of the history books. In a paper published to the Proceedings of the National Academy of Sciences , the team led by archaeologist Stuart Manning identified variations in the carbon 14 cycle at certain periods of time throwing off timelines by as much as 20 years.

Radiocarbon dating

Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants.

The Turin Shroud is a fake. In the latest, but almost certainly not final instalment, they have used modern forensic techniques to show that apparent blood spatters on the shroud could only have been produced by someone moving to adopt different poses — rather than lying still, in the manner of a dead and yet to be resurrected Messiah. Forensic scientist Dr Matteo Borrini of Liverpool John Moores University and Luigi Garlaschelli of the University of Pavia used a living volunteer and real and synthetic blood to try to simulate possible ways that the apparent bloodstains could have got onto the shroud. This could be consistent with someone who had been crucified with their arms held in a Y shape. Unfortunately for shroud believers, however, the forearm blood stains would require the dead body to have been wrapped in the shroud with their arms in a different position — held almost vertically above their head, rather than at an angle of 45 degrees.
