Carbon dating work

Since creatures incorporate carbon-12 and carbon-14 into their bodies at about the same ratio as it occurs in the atmosphere during their lifetimes, by looking at the ratio in the atmosphere today and by comparing it to the ratio as it is found in the specimen we are examining, we are able to determine when the specimen stopped consuming more carbon-14 (i.e. This is, of course, assuming that we know how long it takes for carbon-14 to decay and that we know that the ratio of carbon-12 to carbon-14 in the atmosphere today is about the same as if was during the creature's lifetime.

If either assumption is wrong carbon-14 dating doesn't work.

When an element undergoes radioactive decay, it creates radiation and turns into some other element.

Of course, the best way to understand something is to model it, because the last thing you want to do at home is experiment with something radioactive. Before doing any modeling, you must first understand one key idea: Each atom in a sample of material has an essentially random chance to decay.

Thus, no one even considers using carbon dating for dates in this range.

In theory, it might be useful to archaeology, but not to geology or paleontology.

I know can be hard to wrap your head around, so let's model it with a six-sided die. You can use Lego bricks, pennies, beans—anything you can easily count. Every time you roll a one, put that object into a separate pile.

Count the remaining objects and repeat the process until half of them have decayed. It took a while, but we finally got pretty close to 40 tiles left.

This means that as more of these atoms decay you have a lower rate of radioactive decay. If you roll a one, then that object decays and turns into something else.Perhaps no concept in science is as misunderstood as "carbon dating." Almost everyone thinks carbon dating speaks of millions or billions of years.But, carbon dating can't be used to date either rocks or fossils.The first assumption is fairly reasonable, though some scientists have recently called into question whether or not nuclear decay rates were accelerated in the past (this might change the rate of carbon-14 decay).The second assumption isn't as reasonable seeing as we know that the carbon-12 to carbon-14 ratio changes. God, the Father, sent His only Son to satisfy that judgment for those who believe in Him.
