Sun 101 - which two complementary forces keep the sun from blowing itself up? fusion and magnetism helium and hydrogen photons and magnetism fusion and gravity

Fusion and gravity

Fusion and gravity keep the sun from blowing itself up.  A large amount of energy is released by the sun. Protons are fused together to form helium atoms due to the high heat and pressure at the center of the sun. The Sun does not blow itself up from the outer pressure of nuclear fusion in as much as the inner force of gravity balances it.
