At high geomagnetic latitudes, the carbon-14 spreads evenly throughout the atmosphere and reacts with oxygen to form carbon dioxide.Carbon dioxide also permeates the oceans, dissolving in the water.Half the original quantity of carbon-14 will decay back to the stable element nitrogen-14 after only 5,730 years.(This 5,730-year period is called the half-life of radiocarbon, Figure 1).1 2 At this decay rate, hardly any carbon-14 atoms will remain after only 57,300 years (or ten half-lives). One of the most frequent uses of radiocarbon dating is to estimate the age of organic remains from archaeological sites. Carbon dating, also known as radiocarbon dating, is a method of estimating the age of carbon-bearing materials up to 60,000 years old.Most laboratories measure radiocarbon with a very sophisticated instrument called an accelerator mass spectrometer, or AMS.It is literally able to count carbon-14 atoms one at a time.3 This machine can theoretically detect one radioactive carbon-14 atom in 100 quadrillion regular carbon-12 atoms! AMS instruments need to be checked occasionally, to make sure they aren’t also “reading” any laboratory contamination, called background.

It’s a dilemma for evolutionists, who believe the rocks are millions of years old. Radiocarbon (carbon-14) is a very unstable element that quickly changes into nitrogen.

So rock samples that should read zero are occasionally placed into the instruments to test their accuracy.

I'd frankly rather have my teenage daughters, if and when I have them, date older guys than other teenagers, for reasons I've already mentioned. I have long been in support of 16-17 year olds dating older men in their 20's. My husband sided with her, saying she deserved some privacy and respect. What would a 24 yr old man want in a 16 yr old GIRL (NOT WOm AN)? Regardless of the age of consent, there just is no real valid reason why a 24 yr old NORMAL MAN would want to hang around a 16 YR OLD GIRL unless there was some booty invovled.
