I remember reading that special relativity does not prevent faster-than-light travel, but does prevent accelerating a mass to the speed of light. That doesn't preclude things existing that have always had a faster-than-light velocity.
How such things could originate would be an interesting question for sci-fi.
- simonh 4y agoRight, relativity doesn't say anything about technology or non-relativistic physical processes. It just provides equations, into which you plug in distributions of matter and energy, from which you can calculate a spacetime geometry.
