, “The older an artifact is, the less certain scientists can be about its age” (Barry 2007: 344).Chris Turney of the University of Exeter in England similarly noted: “With radiocarbon, it’s not possible to obtain absolute dates—there’s always a bit of an unknown” (ibid).One of the biggest factors in throwing off carbon dates is the fact that nuclear testing, which began around 1950, “blasted out radiation [into the atmosphere] that scientists see clearly as a spike in the radiocarbon record” (ibid.).

If the dates received from carbon dating are accurate, it would be a huge problem for those who believe in the Genesis account of creation.This idea is advanced, for example, in The Young Earth: C ratio was like before the industrial revolution, and all radiocarbon dating is made with this in mind.How do we know what the ratio was before then, though--say, thousands of years ago?Modern accelerator mass spectrometry (used for radiocarbon dating purposes to separate radiocarbon atoms from stable carbon atoms and count them) is quite precise.The technology involved is fascinating and impressive.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.Measurements can be made with a high degree of precision. Aardsma submitted a sample from a reed mat known to be over 5,000 years old.The measurement, before calibration, came back with an error bar of /- about 60 radiocarbon years. It should be noted that these measurement uncertainties do not increase linearly as one goes back in time.It is assumed that the ratio has been constant for a very long time before the industrial revolution.Is this assumption correct (for on it hangs the whole validity of the system)?
