    Betelgeuse is definitely on the virge of going nova [core collapse]. The shrinking thing is a clue. Shrink and expansion cycles will likely occur for many more years before it gives up the ghost.

    So technically, it could have exploded many years ago. We just can't notice it yet. I find that quite thought provoking.
