Collective particle motions produce galactic structures. Flocking birds in motion produce fractal patterns that resembles the bird’s shape itself with the entire collective entity. Galactic spiral arm filaments contain swarms of high energy supernova particles. Electromagnetic fractal structural patterns are displayed in galaxy jets, bubbles, arm filaments, and the dusty disk. Innumerably more smaller self-similar particles moving in waves, each contains information of the whole entire structure.
