Maybe that is because of a lack of collisions or at their distance in the sky they don’t have the speed, momentum, or gravity pull such as what has occurred to put planets in the position they are in today. Maybe much of the other matter doesn’t have the same density, properties, or orbit/spin as our solar system planets have. It could be that the matter within the Milky Way is trapped in the spin/gravity of all …show more content…

Obviously checking science articles and websites would be a start.
