Carbon dating proven wrong

They are then able to calibrate the carbon dating method to produce fairly accurate results.

Carbon dating is thus accurate within the timeframe set by other archaeological dating techniques.

Carbon dating is somewhat accurate because we are able to determine what the ratio was in the unobservable past to a certain extent.

By taking a carboniferous specimen of known age (that is, a specimen which we are able to date with reasonable certainty through some archaeological means), scientists are able to determine what the ratio was during a specimen's lifetime.

The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.

Carbon dating can only be used to date objects that were once living or even apart of a living organism. It cannot be used to directly date inorganic objects, such as rocks (other radioactive dating methods are used to date radioactive rocks).The result overturned 10 years of hope among Christians that it was real, after the first scientific tests found evidence of blood and serum stains.The earliest documented sighting of the shroud is from 1353, but last week a historian claimed in the Vatican's newspaper that she had found a "missing link" in the Holy See's Secret Archives proving the Knights Templar had safeguarded it during the 13th century.Sue Benford and Joe Marina, from Ohio, suspected the 1988 sample was from a damaged section of the linen shroud repaired in the 16th century after being damaged in a fire.Rogers said: "I was irritated and determined to prove Sue and Joe wrong."However, when he came to examine threads taken in 1978 - luckily from the same section as the 1988 sample - he found cotton in them.

Unfortunately, we aren't able to reliably date artifacts beyond several thousand years.
