Carbon dating calibration
Scientists at Brookhaven National Laboratory and the Physikalish-Technische-Bundesandstalt in Germany have reported "unexplained periodic fluctuations in the [nuclear] decay rates of Si-32 and Ra-226...
strongly correlated in time, not only with each other, but also with the distance between the Earth and the Sun." It is likely that similar discrepancies and fluctuations occur with other nuclear decay rates, such as that of Many people believe that carbon dating has proved that the Earth is millions or billions of years old, much older than the biblically derived date of around 6,000 years.
They showed that the average discrepancy between the known ages and those supplied by radiocarbon dating was 19 years.
The carbon dates made the samples appear older than they really were.
For example, it is well known that carbon dating cannot be used on many types of marine life due to reservoirs of "old" carbon held in sedimentary rocks.Manning chose to test juniper trees (Juniperus phoenicea) that were of a type used for building construction at Taybet Zaman, Jordan and could give unbroken sequences of rings back several hundred years.These tree rings were of known dates between AD 16.However, as explained above, carbon dating is incapable of providing dates in the range of millions or billions of years, and many scientists turn to other forms of dating to derive such extremely long time periods.Some also argue that carbon dating should only be used on samples that fall within the range over which it can measure.
This problem is especially severe in shellfish or anything that eats shellfish; it is not unusual for freshly-killed seals to be dated as several thousand years old.
