Carbon 14 not used for dating updating crysis
Scientists have tried to extend confidence in the carbon dating method further back in time by calibrating the method using tree ring dating.Unfortunately, tree ring dating is itself not entirely reliable, especially the "long chronology" employed to calibrate the carbon dating method.The result is that carbon dating is accurate for only a few thousand years. This fact is born out in how carbon dating results are used by scientists in the scientific literature.Many scientists will use carbon dating test results to back up their position if the results agree with their preconceived theories.But if the carbon dating results actually conflict with their ideas, they aren't too concerned. Thorpe, Nikos Kokkinos, Robert Morkot and John Frankish), Preface to Centuries of Darkness, 1991)So, is carbon dating accurate?"This attitude is clearly reflected in a regrettably common practice: when a radiocarbon date agrees with the expectations of the excavator it appears in the main text of the site report; if it is slightly discrepant it is relegated to a footnote; if it seriously conflicts it is left out altogether." (Peter James, et al. It is for specimens which only date back a few thousand years.Anything beyond that is problematic and highly doubtful. God, the Father, sent His only Son to satisfy that judgment for those who believe in Him.
Unfortunately, we aren't able to reliably date artifacts beyond several thousand years.The method was developed immediately following World War II by Willard F.Libby and coworkers and has provided age determinations in archeology, geology, geophysics, and other branches of science. Unfortunately the ratio of carbon-12 to carbon-14 has yet to reach a state of equilibrium in our atmosphere; there is more carbon-14 in the air today than there was thousands of years ago. In order for carbon dating to be accurate, we must know what the ratio of carbon-12 to carbon-14 was in the environment in which our specimen lived during its lifetime.
