FYI, each of the reactions that astrophysicists hypothesize to occur in supernovae have been seen in fusion reactions here on earth. Not only that, the by-products of the reactions are seen, right down to the flavors of neutrinos expected in each reaction.
I tend to get suspicious when results confirm hypotheses. I get really suspicious when it is claimed things on earth replicate what is happening in outer space. Playing with atoms is a healthy pursuit where an understanding of creation is concerned. I trust the laws of physics continue to perform as God established them from the beginning.
