Carbon dating validity
Carbon dating validity - Fat girls free chats on cam
According to some people, a literal reading of the Bible (taking into account all the genealogies and so forth) yields a creation date of around 7,000 years ago.
Thus, carbon dating would not be useful in, for example, assessing dinosaur bones.
It has become my custom here at Interesting Thing of the Day to choose topics that I think will be unfamiliar to most readers—a sort of implicit “I’ll-bet-you’ve-never-heard-of-this” test.
I think it’s fair to say that any educated person over the age of 10 or so has probably heard of carbon dating.
When an organism dies, it stops acquiring new carbon-14 atoms.
Given that the ratio of carbon-14 atoms to carbon-12 atoms in a living thing is a constant, one can determine the number of each in a sample of organic matter (using sensitive equipment to detect the amount of radiation remaining), and then do a little bit of math to determine how long it’s been since the organism expired.
As is often the case, the controversy over this topic is at least as interesting as the topic itself.
Carbon Copies Carbon dating begins, logically enough, with carbon.Creationist arguments against carbon dating (and every other scientific statement that suggests an older Earth) are extensive, passionate, and very impressive-sounding—though they are most often made by people without actual scientific credentials, and therefore dismissed (with varying degrees of refutation) by the scientific community.As an outsider to this debate, I find it all rather amusing, in a sad sort of way.More importantly, though, the accuracy of carbon dating rests on several crucial assumptions.For one thing, the rate of carbon-14 production in the atmosphere (and thus the level of cosmic ray activity) must have been pretty much constant for the past several dozen millennia.High in the atmosphere, cosmic rays strike nitrogen atoms, producing a radioactive carbon isotope known as carbon-14 (or .
