The fact that we are using chemical rockets is irrelevant to the time it took the Cassini space probe to get to Saturn. It did not take a direct route. It used a gravity-assisted flight path where it hardly used its rockets. They where mainly used just to get off the earth. These flight paths are minimum energy paths that use the gravity of the Sun to guide it and the gravity of the planets to push it.
Actually there are theories that a BEC lives at the center of a black hole while the rest of the matter resides at the event horizon. Mathematically it looks (and acts) the same as black holes as we traditionally think of them now but does not have some of the "problems" that traditional theories have.
