But maybe a "warp drive" is? https://news.ycombinator.com/item?id=6238297 https://news.ycombinator.com/item?id=6238297 ...so then we still get to achieve an effective result of reaching a destination faster than light. ...and since the gravity warps space, and the warp drive exploits warped space, does that mean that the quantum mechanism behind the warp drive is somehow directly related to gravity? the ring would contain exotic matter called negative vacuum energy, a consequence of quantum mechanics. The presence of this toroidal ring of negative vacuum energy is what's required from the math and physics to be able to use the warp trick. It doesn't explicitly mention "gravity", but wouldn't this "negative vacuum energy" have some kind of important relationship with the behavior of gravity?
