Edit: A bunch of yall don’t seem to grasp the concept of a theoretical question

    Bending space isn’t exactly travel, the ship is stationary while the space around it moves. So its not in conflict with the laws of physics while still getting you from A to B “faster” than light.

    Instantaneous travel would mean a wormhole, they do exist on a very small scale, but we are yet to come up with a theoretical way to make them big enough for us to pass and not end up in a random location.

      Yes but as I said, regardless of the method you do to get around the laws of physics, be it bending space or some other novel idea, it still results in the ability to time travel into the past. It creates situations where you can get information before it happens. In a way it places you in two time frames at the same time which is nonsensical. You could send information back to the source before it happened. That is the key point and it breaks causality even if you do it on such a way where you did not actually move. Ie. Wormholes.

      This video is really good. About half way thru it shows that it is not so much the movement but that you arrived somewhere before information could have arrived.

        No i think you get things wrong, you don’t move, you aren’t faster than light, you are just bending the space around you, you can’t travel to the past

          It doesn’t matter if you are moving or bending something and you don’t need to achieve any real velocity. The sources I provided explain why that doesn’t factor. It is simply you are arriving somewhere faster then that is light thru normal space and that alone will allow for time travel to the past.

          People seem to have this concept that if you don’t have to move but can just transport, then it will not break causality. That is not the case.
