It is in knowing what made past cultures cease to exist that could provide the key in making sure that history does not repeat itself.Over the years, archaeology has uncovered information about past cultures that would have been left unknown had it not been with the help of such technologies as radiocarbon dating, dendrochronology, archaeomagnetic dating, fluoride dating, luminescence dating, and obsidian hydration analysis, among others.Imagine a large swimming pool into which one drop of red ink falls each year.The water dilutes the ink so much that even after a few thousand years very little pinkness can be seen in the pool.

“Thus it is necessary to pay [special] attention when using such old carbon data for palaeoclimatic or archaeological interpretations," they added.

It is also worth noting that the half-life used in carbon dating calculations is 5568 years, the value worked out by chemist Willard Libby, and not the more accurate value of 5730 years, which is known as the Cambridge half-life.

Although it is less accurate, the Libby half-life was retained to avoid inconsistencies or errors when comparing carbon-14 test results that were produced before and after the Cambridge half-life was derived.

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.
