Tell me more about the Sun. A star's life is a constant struggle against the force of gravity. Gravity constantly works to try and cause the star to collapse. The star's core, however is very hot which creates pressure within the gas.This pressure couteracts the force of gravity, putting the star into what is called hydrostatic equiliburum.he cloud doesn't collapse into just one large star, but different knots of material will each become it's own protostar. This is why these clouds of material are often called stellar nuseries  they are places where many stars form. As the protostar gains mass, its core gets hotter and more dense.
