Can carbon dating be proven

By measuring whether these levels of Carbon are skewed in an object being radiocarbon dated, future scientists would be able to then know if the object's levels of Carbon have been skewed by fossil fuel emissions. Researchers could then disregard the date and try other methods of dating the object.

Queen's University paleoclimatologist Paula Reimer points out that measuring Carbon will often not be necessary, since archaeologists can usually use the sedimentary layer in which an object was found to double-check its age.

By measuring the rate of production and of decay both eminently quantifiable , scientists were able to estimate that carbon in the atmosphere would go from zero to equilibrium in 30, — 50, years. Since the universe is estimated to be millions of years old, it was assumed that this equilibrium had already been reached.

However, in the s, the growth rate was found to be significantly higher than the decay rate; almost a third in fact. They attempted to account for this by setting as a standard year for the ratio of C to C, and measuring subsequent findings against that. In short, the answer is… sometimes. Sometimes carbon dating will agree with other evolutionary methods of age estimation, which is great.

Most concerning, though, is when the carbon dating directly opposes or contradicts other estimates. At this point, the carbon dating data is simply disregarded.

Carbon Dating Flaws

It has been summed up most succinctly in the words of American neuroscience Professor Bruce Brew: If it does not entirely contradict them, we put it in a footnote. And if it is completely out of date, we just drop it. For example, recently science teams at the British Antarctic Survey and Reading University unearthed the discovery that samples of moss could be brought back to life after being frozen in ice.

That carbon dating deemed the moss to have been frozen for over 1, years. Now, if this carbon dating agrees with other evolutionary methods of determining age, the team could have a real discovery on their hands.

Taken alone, however, the carbon dating is unreliable at best, and at worst, downright inaccurate. Do you like or dislike what you have read?

Look at the rings on that cross section. If you took a core in the four oclock position, you would find some broad rings in the center and then some very narrow rings, which you might compare with a similar reference sample and derive a date.

    But if you took a core in the eight oclock position, you would find broad rings and even wider rings, which may match to a completely different date. Same goes for dendro thermometers, as used by Prof Mann et al.
