The wonder is, surely, that the remaining half come to be accepted. Libby, at the University of Chicago, developed the process of radioactive carbon dating.

Newly created carbon atoms were presumed to react with atmospheric…. Libby, Nobel Lectures, Chemistry — Amsterdam: No seepage of water or other factor has brought additional carbon 14 to the sample since death occurred.

Your contribution may be further edited by our staff, and its publication is subject to our final approval. Libby had developed a method for measuring the carbon content present in organic materials in archaeological artifacts and geological deposits: Agnostic Race or Ethnicity: This is why radiocarbon dates for the past years going back to c. Retrieved June 14, Kamen, to be 5, years, which, compared with the age of the Earth , is a short time but one long enough for the production and decay of carbon to reach equilibrium.

How carbon dating work?

Cosmic rays that enter our atmosphere from outer space strike the earth and transform regular nitrogen nitrogen 14 to radioactive carbon carbon Nitrogen is the precursor to Carbon 14, so the amount of nitrogen in the atmosphere must have always been constant.

Carbon 14 has a half-life of about years. Creation scientists recognize that the problem was the Genesis Flood and the abnormal conditions that existed for centuries after it ended.
