Guys I have an idea. You cool down a bose-einstein condensate and confine it in an electromagnetic field so that it forms a torus shape. The superfludic properties of this state of matter will mean that it can flow with zero friction. Then if you manipulate the electromagnetic field to pump the condensate with kinetic energy so it will begin to spin faster and faster until it reaches relativistic velocities. At such a high speed speed time around the condensate would begin to bend effectively creating an anti gravity device that can be used to quickly traverse the solar system.
