The longest spinning structures in nature. It is many hundreds of times longer even than our Milky Way galaxy, already inconceivably bigger than our solar system. This filament is in a smoothed version of the Illustris computer simulation. The golden comets follow smoothed velocity streamlines, heading toward a galaxy at the filament’s tip (similar to actual trajectories of matter in the simulation, but not quite the same) See “Intergalactic Filaments Spin,” , MNRAS, in press Video: Miguel Aragon-Calvo Music: Samuel Aragon-Huisman
