  After more than forty years since the basic standard model for supernovae Ia
was proposed many astronomers are still hopeful that this phenomenon will
ultimately be understood in terms of Newtonian gravity plus nuclear and
particle physics as they existed in the 1930's. In spite of this fact there are
at least six nagging puzzles in supernova physics that suggest some radical new
physics input may be necessary. "Radical" in this context means a physics idea
that did not exist in the 1930's and that is still not experimentally confirmed
in 2017.
