However, when one starts with the Bible and interprets the information received from carbon dating accordingly, one will soon learn that in no way does carbon dating disprove the young earth.Misconception # 1: Carbon dating can be used to date objects that are millions or even billions of years old Carbon dating is one of the most popular radioactive dating methods used today.
Since the 1960s, scientists have started accounting for the variations by calibrating the clock against the known ages of tree rings.
The technique hinges on carbon-14, a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate.
Organisms capture a certain amount of carbon-14 from the atmosphere when they are alive.
As a rule, carbon dates are younger than calendar dates: a bone carbon-dated to 10,000 years is around 11,000 years old, and 20,000 carbon years roughly equates to 24,000 calendar years.
The problem, says Bronk Ramsey, is that tree rings provide a direct record that only goes as far back as about 14,000 years.
“If you have a better estimate of when the last Neanderthals lived to compare to climate records in Greenland or elsewhere, then you’ll have a better idea of whether the extinction was climate driven or competition with modern humans,” says Paula Reimer, a geochronologist at Queen’s University in Belfast, UK.
She will lead efforts to combine the Lake Suigetsu measurements with marine and cave records to come up with a new standard for carbon dating.
Ironically, despite its popularity, it is also one of the most misunderstood methods of dating.
Many people mistakenly believe carbon dating can be used to date objects that are millions or even billions of years old.
By measuring the ratio of the radio isotope to non-radioactive carbon, the amount of carbon-14 decay can be worked out, thereby giving an age for the specimen in question.
But that assumes that the amount of carbon-14 in the atmosphere was constant — any variation would speed up or slow down the clock.
C-14 is formed in the earth’s upper atmosphere as a consequence of cosmic radiation bombardment.
