... The energy for fusion comes from the massive amounts of gravity and pressure. This causes Hydrogen atoms to collide and fuse into helium atoms. The star is considered stable because the force of fusion causing the star to expand is equal to the force of gravity. This stage ends when it runs out of f ...
