Granted, being that the sun can't go supernova (The Chandrasekhar limit is the mass at which a star is unstable and can go supernova at the end of its life cycle, and it happens to be 1.4 Solar masses... the sun is, well, 1 Solar mass, by definition.), it will instead run out of hydrogen to fuse into helium. Once the sun reaches this point, the equilibrum between "energy made" and gravity breaks, and the sun collapses in on itself, forcing the helium to fuse into carbon. The sudden output of energy transforms the sun into a red giant via expansion. The end.

I wish more people knew about their OBAFGKMLT and stuff.
