http://arxiv.org/abs/0808.3283 This is weird as hell. As far as I knew, nuclear decay rates were not affected by anything, except beta decay under electromagnetic fields. This could possibly have huge consequences in other sciences. Personally, I immediately went to post this in Earth. Paleoclimatologists collect data over hundreds to millions of years based on isotope ratios and nuclear decay rates. Anthropologists, archeologists, geologists— they all do as well, but who knows! By that they mean the fine structure constant. They cite this paper: http://arxiv.org/abs/0806.4317 They also cite this paper in saying: http://arxiv.org/abs/0808.3156 Interesting, all these papers came out at about the same time in 2008. Nice stuff. I'm not a frequent poster in this forum, but I thought it would be placed well here and get some good discussion on these three papers. If it should be moved by a moderator, then go ahead and move it.
