Present day carbon dating
In overview, we see that the radiocarbon dating method is certainly no embarrassment to the Biblical creationist who believes in a young earth."Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.Also, the decay of the earths magnetic field would have direct effects on C14 level, again, giving artificially old ages the farther you go back in time.Finally, carbon dating has been shown untrustworthy with some present day aquatic specimens that were concluded to be thousands of years old.However, because of the difficulties with current C14 dating techniques, the dates produced have been shown to be faulty.Carbon-14 is produced in the upper atmosphere by action of cosmic rays.
Renfrew (1973) called it 'the radiocarbon revolution' in describing its impact upon the human sciences.
Covering the world of tribal art, including: the state of the market; cultural information; legal issues; tribal art events; museum exhibitions; reviews; interviews; general discussions; and other related news.
Relevant information, announcements, and intelligent commentary encouraged.
Carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere; the neutrons required for this reaction are produced by cosmic rays interacting with the atmosphere.
Radiocarbon present in molecules of atmospheric carbon dioxide enters the biological carbon cycle: it is absorbed from the air by green plants and then passed on to animals through the food chain.The problem with the carbon dating method isscientists can not be sure of what the C14/C12 ratio was when the organism died.
