It gets produced in the atmosphere from the sun, the plants breathe it in, and the animals eat the plants. We have all either eaten plants or eaten animals that have eaten plants. The plants are breathing in this carbon dioxide and some of the carbon is radioactive.

If the atmosphere contains. So, you probably have. When a plant or animal dies it stops taking in carbon 14 and whatever it had starts to decay. It was decaying while it was alive, but now there is nothing coming in to replace it. So what they do is compare the amount of carbon 14 in the fossil to the amount of carbon 14 in the atmosphere.

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. While it was alive it should have had. If a fossil only has. In theory the amount of carbon 14 never goes to zero. However, for practical purposes we cannot measure passed a certain amount. There should be no measurable carbon 14 after about 40, — 50, years.

Yet it has proven impossible to find any natural source of carbon below Pleistocene Ice Age strata that does not contain significant amounts of carbon 14, even though such strata are supposed to be millions or billions of years old. These constitute very strong evidence that the earth is only thousands, not billions, of years old. Now think for a minute of what this means.

The textbooks say that coal formed million years ago. However, when coal is tested it still has carbon How is that possible? If all of the carbon 14 atoms would have disappeared at a maximum of , years, why would there still be carbon 14 atoms in coal? Obviously it is not million years old.

Also diamonds, which they say formed millions and millions of years ago, still have carbon 14 in them. So how do you get carbon 14 in diamonds? Again it is obvious that they are not millions of years old. The carbon dating assumptions need to be pointed out. It is also losing carbon 14 through decay. The question is how long would it take the atmosphere to reach a stage called equilibrium?

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. They determined that it would take about 30, years to reach this equilibrium state. They made two bad assumptions after they came up with this calculation. They assumed that the earth was millions of years old and then assumed that they could ignore the equilibrium problem. In other words, burning these fossil fuels dwarfs the atmospheric levels of Carbon, too.

By measuring whether these levels of Carbon are skewed in an object being radiocarbon dated, future scientists would be able to then know if the object's levels of Carbon have been skewed by fossil fuel emissions. Researchers could then disregard the date and try other methods of dating the object. Queen's University paleoclimatologist Paula Reimer points out that measuring Carbon will often not be necessary, since archaeologists can usually use the sedimentary layer in which an object was found to double-check its age.

Q: How can carbon dating work on things that were never alive?

Since the values we get are usually given in ranges, approximations and not exact dates. It would be like trying to measure the distance to the Moon with a wooden ruler. But lucky for us: The more approximations you have about something, the more exactly you know it overall. Given the lengths of time usually involved in radiometric dating, especially uranium dating, I find it remarkable that scientists are able to get the dates down to as small a range as they do.
