Effectively time dilation. Travelling faster than the speed of light supposedly is impossible but just because you break the laws of physics doesn't mean you can now magically get to travel back in time. It's comic book logic.

Wrong.
Lets say these particles arent faster then light but travelled through another dimension, thus taking shortcuts. They would in fact be going back in time.
Einsteins theory can still hold. But can be different if there are more dimensions.
