My theory on how the almighty destroyers stars is that it acquires iron from planets like Mercury and superheated it into a gas or most likely plasma which is then forced through the sun's outer layers into the core and because the star can't generate energy from fusing iron atoms the star won't have enough energy to balance its gravity pushing in thus the star collapses... [spoiler]this would make our sun turn into a red giant because our isn't massive enough... [/spoiler]
