What is the force that keeps a main sequence star from blowing apart?

Question

Quizplus · Accepted Answer

Gravitation is the force that keeps a main sequence star from blowing apart, as it provides an inward force that counteracts the outward pressure of the star's energy being released. The force that keeps a main sequence star from blowing apart is gravitation, which is the force of attraction between all objects with mass. The gravitational force pulls all of the matter in a star towards its center, where the pressure and temperature are high enough to enable nuclear fusion reactions to occur. These reactions release energy in the form of radiation and provide the pressure necessary to counteract the force of gravity and maintain the star's stability. If the force of gravity were to become too strong, the star would collapse in on itself or explode in a supernova.
