Galactic cloud, galaxy, black hole, galactic spin
Free 3D matter-particles and other debris, present in a region of space, may gather under gravitational attraction to form a galactic cloud. Development of a galactic cloud depends on its total matter-content and spin-speed. Galactic cloud (or region within a galactic cloud), with low or no spin-speed, condenses to form a black-hole, under gravitational collapse. Outer regions of a galactic cloud, with higher spin speed, condense to form stable galaxy. A galaxy may remain stable only for a short while. As spin speed of galaxy increases, its matter-content gradually disburses or reverts into universal medium.
