Universal Transportation Ship

This ship can zoom across Universes in milliseconds, and is the most primitive technology to be able to cross Universes, and it can go ~ 27.05 trillion ly/second, (3.907 Harpameters) It can also go as slow as 10 feet per hour, so it makes a great commercial vehicle, being only as big as the average plane. Comes with a bathroom, being the best part. Also it's a cube, but that's unimportant, as all transportation ships are cuboid. (At least until the Cetaversal Travel Ship)
