I do not think that this story is necessarily over though. I would like to see work done on neutron pairs that have not decayed into hydrogen. I suspect that the potential for element production from assemblages of such undecayed pairs is much higher and operative without the intervention of a star.
Other wise we have to rely on the actual death of stars to produce all the matter in the universe and I do not think that conjecture will survive rigorous investigation. We have accepted the reaction chain system far too quickly and have also forgotten that the chain is going the wrong way after Iron.
I find it much easier to allow a few hundred neutron pairs to self pack until they reach a geometry that makes decay into an element(s) probable.
This conjecture avoids all prospective bottlenecks.
