In this section I write a quiet interesting thing, that doesn't related to star formation. You know that gravity is the weakest force than other three fundamental force, but it is the great important and strong in the universe. I think gravity is the only force an important role in star formation, from the nebulae not form a single star, it forms a group of stars. But the distance between the stars are gradually increases. Why didn't they far away from each other there is only force is exist that is gravity(by strong), but gravity has attractive nature then why this happen, which force does this work.
Actually i don't know why it is happen, because i am primitive in classical mechanics. But i think that the force behind this mystery is gravity. Yes it has a face of repulsion, don't mistaken it has not, but it is the responsible for this expansion. Are you heard about the the great "Three body problem", from its solution, it says that in three mutually gravitationally interacting body if it has total positive energy then all three masses can move away from each other, or can escape.Here there is many of bodies therefore the total energy is always positive that will cause to this expansion. Sorry i couldn't have any mathematical expression, of course i don't know the solution of three body problem the above idea is taken from "Classical Mechanics by H.Goldestein", but i believe that this is the reason. If you can solve the many body problem.
