A star is in equilibrium when the radiation pressure matches the force from gravity.

That doesn't mean it doesn't change. The radiation pressure is there to counterbalance gravity, because hydrogen is fusing into helium. Once the hydrogen has burned up, a new equilibrium will occur.

Answer 2

Radiation pressure matches gravity it is stable.Most main sequence stars are in this state like our Sun.

Answer 5

You are an ignoramus. It's nothing to be ashamed about; we all start out in this world knowing nothing. The choice before you now is whether or not you want to become something better, or remain a useless immoral cheating simpleton forever.
