  1. All FTL is a time machine. So let us say I have an FTL tech lets call it a Jump Drive. This Jump drive allows a ship to jump to any location in a 100 light years radius. The mechanics is that when activated the ship disappear for 10 seconds relative to the expansion of the universe and then reappear to their destination after the universe have expanded for 10 seconds. To the people in the ship when the jump is activated the universe disappear for 10 seconds relative to their internal clock then the universe reappear again but it has now shifted so that the ship is now located at their destination and the universe have expanded to a 10 seconds worth of universal expansion. Now how do I use this ship to travel back in time so that I can win the lottery.

  2. ​ @benyseus6325 General Relativity allows time travel so if that is a problem then GR is wrong and you are dealing with physics that are not following established rules.
