When contemplating antigravity thought experiments, one is reminded that a device that feels the earth's gravitational pull is part of a system of two objects, which comprises the earth and the device. The two orbit around their common center of mass, which is, effectively speaking, the same as the earth's center of mass. A mechanism able to counter this equal gravitational attraction between the two objects would have the effect of separating the two from one another a little in their common orbit. I suppose that could either be accomplished by altering the fabric of spacetime for the two objects (and presumably them alone) so that spacetime is less curved; or, alternatively, by increasing the rate at which they orbit one another around their common center of mass.
