They argue that, given the short half life of polonium, these halos could only form under a condition of rapid decay and rapid cooling of magma (Vardiman et al. The accepted scientific model actually does a good job of explaining these halos.Given that almost all of uranium-238's 4.5 billion year half life results from the first step in its decay series where Th, plenty of uranium would still exist long after slow-cooling magma had solidified.According to De Young, string theory: could explore small, temporary adjustments of unseen dimensions, perhaps by the direct hand of the Creator.This might alter the Fermi constant and in turn, adjust nuclear decay rates significantly.Therefore RATE's discovery of ancient C argues strongly against their proposal of accelerated decay, not for it.The RATE team offers two mechanisms for accelerated decay.

From their samples, RATE tries to extrapolate a general discordance across all radiometric dates and offers accelerated decay as an explanation for the discrepancy.

To do so, the alpha particle must have enough energy to overcome the threshold of the strong force, called the Coulomb barrier (De Young 205).

There is a finite probability that alpha particles will have the necessary energy.

The third argument for acceleration offered by RATE is that of isotope discordance.

They start by asserting that radioisotope dates for all isotopes in a rock should always match perfectly.
