other isotope pairs cover intermediate time periods between the spans for carbon 14 and uranium.
For the purposes of this debate, "accurate" means that 95% of the dating errors are within 10% of the measured date, within the time span for which the isotope pair is utilized.
There are about two dozen decay pairs used for dating.
Uranium 235 decay to lead has a half-life of 713 million years, so it is well suited to dating the universe.
Climate records from a Japanese lake are set to improve the accuracy of the dating technique, which could help to shed light on archaeological mysteries such as why Neanderthals became extinct.
Organisms capture a certain amount of carbon-14 from the atmosphere when they are alive. It’s science and many believe “science” to be synonymous with “always true” and therefore don’t question the data given, even when it contradicts the Bible – which also claims to be always true in information that it affirms.So when the two contradict – as they do with the age of the universe and the earth – many abandon the faith and reject the Genesis account because current science tells them that the universe and the earth is billions of years old, and disregard the biblical account – which indicates an age of about 6,000 years.Various geologic, atmospheric and solar processes can influence atmospheric carbon-14 levels.Since the 1960s, scientists have started accounting for the variations by calibrating the clock against the known ages of tree rings.
