Equation proof carbon 14 dating
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.
This change in the amount of 14C relative to the amount of 12C makes it possible to estimate the time at which the organism lived.Recall that atoms are the basic building blocks of matter.Atoms are made up of much smaller particles called protons, neutrons, and electrons.The last figure I heard was that there are currently eight nuclear subs on our ocean floors. It doesn't work for sea creatures and other things that are under water. Then they measure how much is left in the specimen when they find it. It comes from cosmic rays that rain down on the earth (and us) from outer space.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.
The amount of carbon-14 in the atomosphere is, on an average, relatively constant.
Plants take in carbon-14 through the process of photosynthesis.
Libby and coworkers, and it has provided a way to determine the ages of different materials in archeology, geology, geophysics, and other branches of science.
Some examples of the types of material that radiocarbon can determine the ages of are wood, charcoal, marine and freshwater shell, bone and antler, and peat and organic-bearing sediments.
A fossil found in an archaeological dig was found to contain 20% of the original amount of 14C. I do not get the $-0.693$ value, but perhaps my answer will help anyway.
