Later, after all the particles were dispersed, they began to cool down by radiating energy and in return, Hydrogen and other massive molecules were created. As time passed, they began to pull on each other's atomic and gravitational forces. This caused a fusion which caused another explosion which sent out more massive atoms. They eventually combined to create planets, meteorites, astroids, stars, and numerous other masses.
