Imagine a giant launching technology that looks like a complex sewing needle with a large open hole part with a spherical object in the middle. Imagine a ship going through phases around it, and eventually reaching a point where it is balanced on its pelmet. In an array of phases going through the hole and around the apparatus it generates torque, after enough phases have passed it reaches a point of balance which it the, through magnetic friction, starts to perform a unnatural rhythmic launch, wobbling left and right and tilting up and down, and maintains this constant in 0 gravity never breaking until stopped. By generating immense speed over time we can reach any star.
