Topics: can someone explain to me the so-called issues with carbon dating 14?

Archeologists use various methods to date objects. Inscriptions, distinctive markings, and historical documents can all offer clues to an artifact's age. And if the artifact is organic like wood or bone researchers can turn to a method called radiocarbon dating. In this interactive, learn how radiocarbon dating works, what it takes to determine a date in the lab, and why it's challenging to pinpoint a date precisely.

Recently, I came across an invitation to participate in a prayer for the betterment of self and, which sounded rather grand, for the whole of humanity.

Dear Mr. Owen, Thanks for writing to ABR. Regarding the location of Mount Sinai, about the only thing Mr. Jacobovici got right that it IS in the Sinai proper. The Galatians 4:25 reference should not be equated with modern day Saudi Arabia. See two articles by Gordon Franz here: http://www.biblearchaeology.org/./.-Saudi-Arabia.aspx http://www.biblearchaeology.org/./.-Saudi-Arabia.aspx Hope this helps--Henry Smith

The basic assumptions are: 1.) the basic laws of physics are unchanged 2.) the amount of carbon 14 as a percentage of total carbon has not changed. Carbon dating could be flawed by surges in the production of carbon 14 from nitrogen by accelerated neutrons. (like nuclear blast, solar flare-up, radiation exposure) Likewise, it could be flawed by drops in carbon 14 production by a lull in accelerated neutrons.( High dust in the atmosphere, quiet periods in the sun s cycle).

It could work, but how accuarte would it be? Let s take a look at a few website quotes. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Source: http://www.mnsu.edu/emuseum/archaeology/dating/radio_carbon.html "Carbon 14 decays at a slow but steady rate and reverts to nitrogen 14. The rate at which Carbon decays (Half-life) is known: C14 has a half-life of 5730 years. Basically this means that half of the original amount of C14 in organic matter will have disintegrated 5730 years after the organisms death; half of the remaining C14 will have disintegrated after another 5730 years and so forth. After about 50,000 years, the amount of C14 remaining will be so small that the fossil can t be dated reliably. To discover how long an organism has been dead (to determine how much C14 is left in the organism and therefore how old it is), we count the number of beta radiations given off per minute per gram of material. Modern C14 emits about 15 beta radiations per minute per gram of material, but C14 that is 5730 years old will only emit half that amount, (the half-life of C14) per minute. So if a sample taken from an organism emits 7.5 radiations per minute in a gram of material, then the organism must be 5730 years old. The accuracy of radiocoarbon dating was tested on objects with dates that were already known through historical records such as parts of the dead sea scrolls and some wood from an Egyptian tomb. Based on the results of the Carbon 14 test the analysis showed that C14 agreed very closely with the historical information." Source: http://www.teachervision.fen.com/science/history/6124.html "Carbon dating uses an exponential decay function, C(t) = 100 • e^(-.000121t), to show the percentage of carbon-14 remaining in an object that is t years old. In other words, this function takes in a number of years, t, as its input value and gives back an output value of the percentage of carbon-14 remaining. So, if you were asked to find out carbon s half-life value (the time it takes to decrease to half of its original size), you d solve for t number of years when C(t) equals 50, because fifty percent represents one half. Carbon dating does have certain limitations. After about 50,000 - 70,000 years, almost all of the carbon-14 in any remains will have broken down. So, objects older than that do not contain enough of the isotope to be dated. Conversely, the method doesn t work on objects that are too young." ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ I would say given these two sources, Carbon dating is accurate for anything close to 5730 years of age. As you go byond 50000 years of possible age, carbon dating becomes vitually useless because not enough carbon-14 is left to measure decay. Conversely, if it is substatially younger than 5730 years, there would likely have been not enough carbon-14 decay to be mesurable with any use.

That depends on what you mean by "Christians." If by Christians, you mean the wide variety of sects and religions, it means the same as it does to anyone else. A scientific way of determining the age of artifacts. Now if by "Christian" you mean the holier-than-though, young-earth Creationists. It is a problem, because the scientific process disproves the time line of the Old Testament.

Beta Analytic uses Accelerator Mass Spectrometry (AMS) technology, which gives the most advanced precision and accuracy for Carbon-14 measurements.

The radiocarbon dating lab is based in Miami, Florida, and is the world leader in Carbon-14 analyses since 1979. It has forwarding offices in Australia, Brazil, China, Japan, South Korea, Taiwan, and the UK.

Beta Analytic’s radiocarbon dating fees are inclusive of δ13C measurements by Isotope Ratio Mass Spectrometry (IRMS) and calendar calibration when applicable, δ18O for carbonates, and δD (deuterium) and δ18O for water. The lab also offers C:N, %C and %N measurements on collagen extracted from non-cremated bones in addition to δ15N and δ13C at no additional cost for samples sent for radiocarbon dating.
