So when you hear of a date of 30, years for a carbon date we believe it to be early after creation and only about 7, years old.

If something carbon dates at 7, years we believe 5, is probably closer to reality just before the flood. Robert Whitelaw has done a very good job illustrating this theory using about 30, dates published in Radio Carbon over the last 40 years.

One of the impressive points Whitewall makes is the conspicuous absence of dates between 4, and 5, years ago illustrating a great catastrophe killing off plant and animal life world wide the flood of Noah! I hope this helps your understanding of carbon dating. If you have any more questions about it don't hesitate to write. I just listened to a series of lectures on archaeology put out by John Hopkins Univ.

The lecturer talked at length about how inaccurate C14 Dating is as 'corrected' by dendrochronology. The methodology is quite accurate, but dendrochronology supposedly shows that the C14 dates go off because of changes in the equilibrium over time, and that the older the dates the larger the error. Despite this she continually uses the c14 dates to create 'absolute' chronologies. She says this is ok so long as you take into account the correction factors from dendrochronology. They conveniently forget to mention that the tree ring chronology was arranged by C14 dating.

The scientists who were trying to build the chronology found the tree rings so ambiguous that they could not decide which rings matched which using the bristlecone pine. So they tested some of the ring sequences by C14 to put the sequences in the 'right' order.

Once they did that they developed the overall sequence. And this big sequence is then used to 'correct' C14 dates. Talk of circular reasoning!!!! Even if the rate of decay is constant, without a knowledge of the exact ratio of C12 to C14 in the initial sample, the dating technique is still subject to question. Traditional 14C testing assumes equilibrium in the rate of formation and the rate of decay.

In fact, it has fluctuated a great deal over the years.

This variation is caused by both natural processes and human activity. Humans began making an impact during the Industrial Revolution.

  6. The isotope decreased by a small fraction due to the combustion of fossil fuels, among other factors. The answer to the problem of fluctuating amounts of this important isotope is calibration.

    How accurate is radiocarbon dating?

    Standard calibration curves are now used for more accurate readings. These curves indicate the changes in Carbon throughout the years and modifies the end result of the tests to reflect that.

    Though the calibrated date is more precise, many scholars still use the uncalibrated date in order to keep chronologies consistent in academic communities. As the lecture detailed, it is only accurate from about 62, years ago to 1, A. There is a sizable amount of time before and after that period that cannot be investigated using this method. Also, archaeologists cannot use their hands to touch the samples or smoke near them. They risk seriously altering the result of the test. If an archaeologist wanted to date a dead tree to see when humans used it to build tools, their readings would be significantly thrown off.

    This is because radiocarbon dating gives the date when the tree ceased its intake of Carbon—not when it was being used for weapons and other instruments!
