Potassium argon radiometric dating

This radioactive carbon 14 slowly decays back into normal, stable nitrogen.

Extensive laboratory testing has shown that about half of the C-14 molecules will decay in 5730 years. After another 5730 years half of the remaining C-14 will decay leaving only ¼ of the original C-14. In theory it would never totally disappear, but after about 5 half lives the difference is not measurable with any degree of accuracy.

At some point you would be putting it in and it would be leaking out at the same rate.

You will not be able to fill the barrel past this point of equilibrium.

The C-14 in the plant or animal will begin to decay back to normal nitrogen.

The older an object is, the less carbon-14 it contains.

This would prove the earth is not yet 30,000 years old!

Potassium Argon dating: "Potassium Argon dating is based on many of the same assumptions and gives wild dates shown below. "Apart from very 'modern' examples, which are really archaeology, I can think of no cases of radioactive decay being used to date fossils."Ager, Derek V., "Fossil Frustrations," New Scientist, vol. An object's supposed place on the geologic column determines the method used to date it. "One part of Dima [a baby frozen mammoth] was 40,000, another part was 26,000 and the "wood immediately around the carcass" was 9-10,000. Pewe, Quaternary Stratigraphic Nomenclature in Unglaciated Central Alaska, Geological Survey Professional Paper 862 (U. Last spring he was re-evaluating Homo erectus skulls found in Java in the 1930s by testing the sediment found with them.

In the same way the C-14 is being formed and decaying simultaneously.

A freshly created earth would require about 30,000 years for the amount of C-14 in the atmosphere to reach this point of equilibrium because it would leak out as it is being filled.

In order to find the length of time since the candle was lit we would be forced to make some assumptions.

We would, obviously, have to assume that the candle has always burned at the same rate, and assumes an initial height of the candle. Similarly, scientists do not know that the carbon-14 decay rate has been constant.

This is why most people say carbon dating is only good for objects less than 40,000 years old.
