A speculative form of faster‑than‑light information transfer that uses principles derived from relativity warp drives—i.e., manipulating spacetime geometry to carry a signal without locally exceeding light speed. This could involve creating a warp bubble for a light pulse, sending signals through a traversable wormhole, or exploiting relativistic effects to make signals appear superluminal while respecting causality (see Preserved Causality Hypothesis). Unlike quantum entanglement (which cannot transmit usable information), relativity FTL communication would allow sending actual messages across interstellar distances in negligible time.
