What primary physical process powers a star by forcing hydrogen atoms to fuse?

Answer

Nuclear fusion

Stars operate through nuclear fusion, a process occurring within their cores. Intense pressure and extreme heat cause hydrogen atoms to collide and combine, creating helium. This reaction releases massive amounts of energy, which creates the outward pressure necessary to balance the inward pull of gravity, a state known as hydrostatic equilibrium.
