However, an equilibrium is maintained due to the explosions caused by nuclear fusion occurring in the core, meaning that the star doesn't crush itself, peko.However, they were stars with more than 30 times the mass of the Sun, peko.HIGH GRAVITY!But a star cannot continue fusing forever - at some point, it will burn all the fuel it has and fusion will cease, peko.NUCLEAR FUSION!The gravity of a star this massive is so great that it contracts itself towards the core...Nope!The SunThat's what they call a "supernova", peko. Have you really never heard of it, Kanata-chan?When this occurs, the star can no longer fight it's own massive gravitational energy and will rapidly contract...to a single point with an explosion, peko.
