Here's some info about how carbon dating is based on assumptions, that may not be true.

Quote: "Although this technique looks good at first, carbon-14 dating rests on at least two simple assumptions. These are, obviously, the assumption that the amount of carbon 14 in the atmosphere has always been constant and that its rate of decay has always been constant. Neither of these assumptions is provable or reasonable."
