Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.
One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.
For a rare event it happens pretty damn often — one million carbon-14 atoms in your body decay into nitrogen every minute!
by Dr Carl Wieland An attempt to explain this very important method of dating and the way in which, when fully understood, it supports a ‘short’ timescale.
In fact, the whole method is a giant ‘clock’ which seems to put a very young upper limit on the age of the atmosphere.
As soon as it dies, however, the C ration gets smaller.
In other words, we have a ‘clock’ which starts ticking at the moment something dies.
The article is in straightforward language and the non-technical reader could profitably work through it.
