If you've somehow made A and B closer together, then you've made a wormhole, not a warp drive. Wormholes also come with "closed time-like loops", which allow for time travel.
- spullara 14y agoI don't know. This isn't something covered by special relativity. You certainly don't need a wormhole though. http://curious.astro.cornell.edu/question.php?number=575 http://curious.astro.cornell.edu/question.php?number=575
- nessus42 14y agoYes, there are parts of the universe traveling away from us at faster than the speed of light. In fact, it's quite likely that the universe is infinitely big and an infinitely large part of it is traveling away from us at faster than the speed of light. This fact, however, does not allow information to be transmitted between two points in space at faster than the speed of light. That's the important constraint here. Causality is only violated when you transmit INFORMATION between TWO POINTS at faster than the speed of light.
