Is carbon dating accuracy or not
But new research shows that commonly accepted radiocarbon dating standards can miss the mark—calling into question historical timelines.
(4.) Traditional 14C testing assumes equilibrium in the rate of formation and the rate of decay.
Pre-modern radiocarbon chronologies rely on standardized Northern and Southern Hemisphere calibration curves to obtain calendar dates from organic material.
These standard calibration curves assume that at any given time radiocarbon levels are similar and stable everywhere across each hemisphere. "We went looking to test the assumption behind the whole field of radiocarbon dating," Manning said.
One of the impressive points Whitewall makes is the conspicuous absence of dates between 4,500 and 5,000 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.
Example: wood found in a grave of known age by historically reliable documents is the standard for that time for the C14 content.
