Can carbon dating be wrong dating your next door neighbor
He claimed that it was capable of dating animal, plant and human remains of fairly recent origin. As they say on Star Trek, we are all carbon based units.Laboratory research has shown that the radioactive decay of Carbon-14 occurs in a half-life of 5,73040 years through beta decay that causes the Carbon-14 to revert back to Nitrogen-14.The process would continue, halving the amount left every 5,730 years until, theoretically, nothing remained of the original pound.(approximately 78% of atmospheric gases) by thermal neutrons which come from the powerful cosmic radiation, primarily generated by the sun.
The lower the amount of Carbon-14, the longer it has been since death occurred.The theoretical limit of the usefulness of Carbon-14 dating would only be 50,000 years.This would be the amount of time it would take for nine half-lives, and after that there would not be enough left to measure accurately.There is no instrument on earth that can detect Carbon-14 in a specimen that is supposedly older than 18 half-lives. There are, however, many false assumptions that must be made in order to derive Carbon-14 dates and the knowledge of these false assumptions demonstrates the uselessness in this other-wise supposedly useful not varied over the years. There is ample evidence to prove that quite the opposite is true.Experiments done with the radioactive isotopes of Uranium-238 and Iron-57 have shown that rates not only do vary, but can, in fact, be altered by changing the environment surrounding the samples.
