Once the Flood processes ceased, C-14 began a slow build-up to equilibrium with C-12—a build-up not yet complete.

The method assumes, among other things, that the earth's age exceeds the time it would take for C-14 production to be in equilibrium with C-14 decay.

Since it would only take less than 50,000 years to reach equilibrium from a world with no C-14 at the start, this always seemed like a good assumption.

Obviously, if half the C-14 decays in 5,730 years, and half more decays in another 5,730 years, by ten half-lives (57,300 years) there would be essentially no C-14 left.

Thus, no one even considers using carbon dating for dates in this range.

If the pressure is increased to 10 atmospheres carbon (graphite) is observed to melt at 3550 °C.

Carbon has been known since ancient times in the form of soot, charcoal, graphite and diamonds.

Rocks and fossils, consisting only of inorganic minerals, cannot be dated by this scheme.

Carbon normally occurs as Carbon-12, but radioactive Carbon-14 may sometimes be formed in the outer atmosphere as Nitrogen-14 undergoes cosmic ray bombardment.

In 1985 an entirely new form of carbon was discovered in which carbon atoms join to make a sphere called a buckminsterfullerene or buckyball, after Buckminster Fuller, who created buildings with a similar appearance.
