14c and carbon dating

19 Sep

The level of atmospheric C is not constant due to human activity, in part because of human combustion of fossil fuels and in part because of above-ground testing of the largely defensive weapon of the thermonuclear bomb.Therefore dates must be calibrated based on Radiometric dating in general, of course, poses a huge problem for people who believe that the universe is 6000-odd years old.

When an organism dies, this ratio (1 to 1 trillion) will begin to change.Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.The amount of 12C will remain constant, but the amount of 14C will become less and less.The smaller the ratio, the longer the organism has been dead.Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.The number of protons in the nucleus of an atom determines the element.This has caused many in the church to reevaluate the biblical creation account, specifically the meaning of the word “day” in Genesis 1.With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.A critical assumption used in carbon-14 dating has to do with this ratio.It is assumed that the ratio of 14C to 12C in the atmosphere has always been the same as it is today (1 to 1 trillion).
