Changes to the shape of space-time willl still only travel at the speed of light, so I don't see how that would enable you to travel faster than light for any meaningful distance, as the warp bubble itself would be unable to keep up with the vehicle.
- wcoenen 5y agoWithin the event horizon of a black hole, spacetime seems capable of "moving" towards the center faster than the speed of light. That's why light cannot escape, right?
- designium 5y agoNo, speed of light will not move faster inside in the event horizon. It is still at the same speed. But the spacetime is so distorted that a photon will start orbiting the singularity, thus it doesn’t get out of the event horizon. https://phys.org/news/2014-03-orbit-black-hole.html https://phys.org/news/2014-03-orbit-black-hole.html
- zamadatix 5y agoThe speed of light in a patch of space does not change but space itself can warp faster than the speed of light. The link you post describes a region in certain conditions where light can orbit not that that is the fate of all light falling into a black hole.the end talks about the always orbitally unstable regions beneath that being referred to here.
- designium 5y agoPerhaps when we discover why the universe is expanding, then we may have or not a solution for this. The expansion of the universe can be faster than the speed of light. Would it be possible to use that to create FTL travel?
