So I sent Dean a request for permission to include his painting here on our website and he graciously agreed to share it with us. Here are some things to consider about carbon dating.

Carbon dating is used to work out the age of organic material — in effect, any living thing. If the fossil only contains half as much carbon 14 as the atmosphere, it is assumed to have been dead for one half-life, or 5, years.

As we mentioned above, the carbon to carbon ratio in the atmosphere remains nearly constant. In theory the amount of carbon 14 never goes to zero.

Various geologic, atmospheric and solar processes can influence atmospheric carbon levels. So what they do is compare the amount of carbon 14 in the fossil to the amount of carbon 14 in the atmosphere.

My dear friend Fr. They wanted to figure out how long it would take the atmosphere to reach a point where the construction rate and the destruction rate of carbon 14 was the same.

The atmosphere has very distinctive layers to it.

This has changed over the past few decades because of the dramatic advances in digital imaging technologies and computer power. However, this is the logic most scientists have. I make my second presentation on Thursday, February 22nd at 7: It can be used on objects as old as about 62, years.

The technique hinges on carbon, a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate.
