Abstract

Precision measurements of gauge couplings at particle accelerators strongly suggest that the standard model fields are unified at about 1016 GeV. This talk will consist of a brief review of this evidence and also how in such a setting variations in α em lead to much larger variations in Λ QCD . I will then describe how variations in the strong force will impact upon nuclear astrophysics, considering in particular the stability of di-nucleons and stellar and primordial nucleosynthesis. (Based upon collaborations with T. Dent and with A. Csoto, H. Oberhummer and H. Schlattl.)
