Half life dating methods
As our knowledge continues to grow, what we know continues to be in agreement with Scripture.
When creation scientists studied granite samples, they made interesting discoveries.Outside the range of recorded history, calibration of the 14 clock is not possible.This means the above calculations are only evolution speculation and NOT backed up by real science.Afterward, less carbon would be available to enter the atmosphere from decaying vegetation.With less carbon-12 to dilute the carbon-14 continually forming from nitrogen in the upper atmosphere, the ratio of carbon-14 to carbon-12 in the atmosphere would increase.Actually, that ratio may have been quite different.
For example, a worldwide flood would uproot and bury preflood forests.
However, for the last 3,500 years, the increase in the ratio has been extremely slight.
Radiocarbon dating of vertical sequences of organic-rich layers at 714 locations worldwide has consistently shown a surprising result.
If the atmosphere's ratio of carbon-14 to carbon-12 has doubled since the flood and we did not know it, radiocarbon ages of things living soon after the flood would appear to be one half-life (or 5,730 years) older than their true ages.
If that ratio quadrupled, organic remains would appear 11,460 (2 x 5,730) years older, etc.
Cosmic radiation striking the upper atmosphere converts about 21 pounds of nitrogen each year into radiocarbon (carbon-14).
