Carbon dating assumptions

A little about the video
Yes, I want to follow Jesus. I am a follower of Jesus. I still have questions. I'm confident that we can improve the accuracy of carbon dating somewhat, but only if we acknowledge and carefully study the various factors which may play a role in how reliable our foundational assumptions are. In order for carbon dating to by accurate certain foundational assumptions must first be true. We must assume to know that the rate at which carbon decays into nitrogen hasn't somehow changed throughout the unobservable past.

Argon–argon dating - Wikipedia

Carbon dating , or carbon dating, is a method for comparing the ages of organic materials such as bones or artifacts made from anything that once lived. Unlike many other radiometric dating methods, carbon dating has been calibrated for historical periods and within that range can give reliable results. The technique is based on comparing the levels of 14 C and 12 C isotopes in the sample. In the meantime, however, the 14 C will combine with oxygen in the atmosphere to form carbon dioxide , which enters the food chain via photosynthesis in plants.

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.
