SUMMARY
Main sequence stars primarily rely on radiation pressure to counteract gravitational collapse, rather than electron degeneracy pressure. While electrons in these stars do exhibit some degeneracy effects due to quantum mechanical principles, this phenomenon becomes significant only after the star has cooled and contracted, leading to increased density. The discussion clarifies that the central material of main sequence stars behaves like an ideal gas, maintaining stability until conditions change. Thus, electron degeneracy pressure is not a dominant factor during the main sequence phase.
