Answer 10

Fusion inside a star is like hulk preventing the walls of the star from collapsing into itself.
As the star exhausts its fuel, hulk goes from looking like this http://www.anorak.co.uk/wp-content/gallery/extreme-bodybuilding/extreme_bodybuilder_02.jpg to this http://www.homefitnessadvisor.com/wp-content/uploads/2011/08/Skinny-Guy-Flexing-e1313339349425-223x300.jpg and can't hold up the walls of the star and the star collapses under it's own "weight". Moral of the story: eat too much and you'll collapse in on yourself.

Answer 11

m pretty sure hulk is not involved in all this :-/
