Scientists take this, and produce calibration curves, which are applied to the carbon dating process.
This removes the first assumption..the amount of C-14 is thought to be constant.
Hovind goes on to claim "This also means that plants and animals that lived in the past had less C-14 in them than do plants and animals today.
Just this one fact totally upsets data obtained by C-14 dating." A study of plants of the past, using tree-rings, confirms a direct correlation between C-14 levels and the earth's magnetic field, over the last 8,000 years.
He says "Although this technique looks good at first, carbon-14 dating rests on two simple assumptions.
They are, obviously, assuming the amount of carbon-14 in the atmosphere has always been constant, and its rate of decay has always been constant." Remember the tree-ring data..tells us how much carbon-14 was in the atmosphere at a given time.
It varies because of the earth's magnetic field.Scientists know that it is not, and correct for this. There is no data to indicate otherwise, and Hovind presents none.He does give an illustration of a candle burning, saying it would be like assuming the candle always burned at the same rate.It does not "upset" data obtained by C-14 dating..confirms C-14 dating!Hovind goes on to show that he knows absolutely nothing about the science of Carbon Dating.There are many periods of decreasing C-14, which disproves his theory that the earth is young based on C-14 equilibrium.For More Reading How Good are those Young Earth Arguments: Carbon Dating Want to learn more about creation science?In the following article, some of the most common misunderstandings regarding radiocarbon dating are addressed, and corrective, up-to-date scientific creationist thought is provided where appropriate. Radiocarbon is used to date the age of rocks, which enables scientists to date the age of the earth.Radiocarbon is not used to date the age of rocks or to determine the age of the earth.Sometimes, it is near zero, other times it is greatly increased.Therefore over time, we could have reached equilibrium many times. Since the rate of C-14 production is far from constant, the theory that the earth is less than 30,000 years old based on equilibrium is unreliable.
