So, the FTL gravity pulses used in David Weber's Honorverse series (sci-fi space opera) aren't possible. :(

- negativity 13y agoBut 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?
- pdonis 13y agowouldn't this "negative vacuum energy" have some kind of important relationship with the behavior of gravity? It seems like it would, yes, but I haven't really seen this discussed in papers on wormholes.
- protomyth 13y agoWell, a hand-wavy explanation could be the gravity interacts with hyperspace[1] allowing the detector to pick it up FTL. 1) it seems his version of hyperspace has a lot of interaction with gravity (e.g. gravity waves like The Deep)
