It is interesting how almost everyone assumed it was entirely consuming the sun, as I'm the only one I've spoken to in person or that I remember reading about in this thread thinking the opposite. Even if I'm right, that statistic alone shows that they needed to do a lot better job of explaining it, even if it was just a throwaway line like, "When the sun goes dark it still has enough nuclear reaction to restart itself, but if we go beyond that it will never recover, or go supernova, or black hole, or whatever."
