(Ham et al., page 72.) As with Assertion 1, Assertion 2 fails to account for the tree-ring calibration which is a routine part of modern radiocarbon dating.Although no convincing argument for a change in the speed of light over time has been made, the question is irrelevant to the validity of tree-ring calibrated radiocarbon dates.

One is that the carbon 14 concentration in the carbon dioxide cycle is constant.By the application of some very well thought-out techniques, Libby and his colleagues have actually not only identified the radiocarbon in nature, but have also made quantitative estimates thereof.Since this carbon in the atmosphere mostly becomes attached to oxygen to form carbon dioxide, and since the carbon dioxide is ingested by plants and animals and is incorporated in their biological structures, and further, since this process stops at the time of the death of the specimen, the percentage of radiocarbon among the normal carbon atoms in its system can be used to establish the date at which the specimen stops metabolizing.7-68 There is no doubt that this constitutes a very ingenious and powerful dating tool, provided only that the inherent assumptions are valid.The other is that the cosmic ray flux has been essentially constant—at least on a scale of centuries.7-69 To which we might add the assumption of the constancy of the rate of decay of the carbon 14 atoms, the assumption that dead organic matter is not later altered with respect to its carbon content by any biologic or other activity the assumption that the carbon dioxide content of the ocean and atmosphere has been constant with time, the assumption that the huge reservoir of oceanic carbon has not changed in size during the period of applicability of the method, and the assumption that the rate of formation and the rate of decay of radiocarbon atoms have been in equilibrium throughout the period of applicability.Every one of these assumptions is highly questionable in the context of the events of Creation and the Deluge.Your T-shirt could soon contain the same carbon-14 as William the Conqueror’s robe from 1066 AD, scientists warn.
