When it comes to high-speed collisions, nobody here on Earth has anything on black holes. Astronomers have witnessed a new first: two high-speed knots of matter colliding in a sort of rear-end impact. They saw this after creating a time-lapse video of a super-speed jet of plasma as it shot out of a supermassive black hole. The knots of matter were inside the black hole until it blasted them out-and into each other.
