A new Renaissance Computing Institute (RENCI) animation created from a mathematical model shows a black hole moving supersonically through an interstellar gas cloud. This phenomenon often occurs in multiple star systems, where a companion star provides the gas cloud. The gravity of the black hole pulls the gas inward. Early on in the process, a wake forms behind the black hole, much like the wake behind a motorboat. Unlike a motorboat wake, it begins to move back and forth after a while until it whips all the way around the black hole, forming an accretion disk of gas falling into the hole.
Very interesting, I leave you with doubts that video, and can change its meaning?
