Radiocarbon dating, or carbon dating, is a radiometric dating method that uses the naturally occurring radioisotope carbon-14 (14C) to determine the age of carbonaceous materials up to about 58,000 to 62,000 years.

The water dilutes the ink so much that even after a few thousand years very little pinkness can be seen in the pool.Also, the imaginary ink in water slowly disappears with a half-life of 5,730 years. If you could watch 100 carbon-14 atoms (or red ink molecules which, in this analogy, represents carbon-14), you would on rare occasions see a carbon-14 atom decay and become nitrogen-14.After 5,730 years, half (or 50 carbon-14 atoms) would remain.After another 5,730 years only half of those 50 (or 25 carbon-14 atoms would remain.) Think of the red ink molecules slowly disappearing at the same rate.One day, about 5,000 years ago, most of the water suddenly drained from the pool.Since then, the amount of water only fills a bathtub, but one drop of red ink continued to fall into the bathtub each year.

With so little water to dilute the red ink, the water’s pinkness steadily increased, but not indefinitely. Because each molecule of this imaginary ink has a half-life of 5,730 years, a point was reached when as many molecules of red ink disappeared each year as fell into the bathtub.

Therefore, today the degree of pinkness in the bathtub’s water is not changing.

In this analogy, the red ink represents carbon-14 that forms in the upper atmosphere at the rate of 21 pounds per year and spreads throughout the biosphere.

The swimming pool’s water represents the huge amount of the normal carbon (carbon-12) that was in the biosphere before the flood.

Because about half of today’s surface water was in the subterranean chamber before the flood, there was less surface water and more forested land area.

Most of the carbon in the vast preflood forests is now our coal and oil deposits.
