What is the force that keeps a main sequence star from collapsing on itself?

Question

Quizplus · Accepted Answer

Radiation pressure from the fusion occurring in the core of the star creates an outward force that counterbalances the force of gravity trying to collapse the star. The force that keeps a main sequence star from collapsing on itself is radiation pressure caused by the outward pressure of the star's own radiation. Gravity is constantly pulling the star inward, but radiation pressure prevents it from collapsing. The other options (magnetism, the strong force, and electron degeneration pressure) are not relevant to this process.
