I'm not sure new physics will help with that. Faster than light travel, if possible, would really screw with causality. Besides, we can always travel the slow

  Well, it depends on what you mean, I guess. You can't travel through space faster than light, but if we could figure out how to create and use wormholes, for example, we could potentially travel to places that are out of reach when traveling through space.

    No, that would have the same problem - being able to send information back in time. We also have no theory of traversable wormholes that doesn't involve imaginary energy, so it's just fantasy.

      I don't know much about this stuff, so take this as me being genuinely curious. > No, that would have the same problem - being able to send information back in time. Would it? If a wormhole is connecting two points in spacetime, then could time also be traversed at the same time? E.g. traveling through the wormhole would move you far enough forward in time to not cause any problems?

        Sure, you can travel 1 light year if you also go 1 year ahead in time without any causality issues.

  > Faster than light travel, if possible, would really screw with causality Well, the assumption abiut causality is based on our current understanding of physics. Perhaps we just don't understand the problem well enough and there are ways around the causality problem
