I heard the reaction speed of nucleosynthesis (in supernova) predicted by the
current theory is 2 to 3 times slower than experimental data (obtained by an
accelerator?). If true, why is this? Does this mean new phenomena take place
during nucleosynthesis that the standard model fails to predict? Or is this just
a matter of tuning/tweaking another fudge factor etc.?
