That's a different underlying cause. Nobody would say that a rail gun that shoots ball bearings at near C breaks FTL just because you turn it.
This is more that space time isn't euclidean. You can see this in how gravitational lensing can create longer straight line paths between two points. Just because you could send light down one pathway and it ends up later than something moving less than C, doesn't mean that you went FTL in a way that breaks causality. An Alcubierre drive is 'just' dynamically modifying the shape of space time to make more useful pathways.
- PaulHoule 5y agoI don't think you can really use the paths.
- monocasa 5y agoWhy not? If you can bend space time into the bubble in the first place, why can't you bend it back? The main issue I've heard with 'popping' the bubble isn't that you cut yourself off from the rest of space permanently, it's that there's a collection of everything that would have been along your path time dilated sitting right at the edge of the bubble that flies into the bubble all at once and is pretty nasty for anything in the bubble.
