I don't fully understand; > if you're at A, you can travel faster than the speed of light and arrive before B happens But if we assume A and B happen "at the same time" and your frame of reference is closer to A than B right? As the light showing B happening is still traveling to the observer while A has already arrived. If that's the case, > Then, after B happens, you can travel back to before A happens. Doesn't make sense, If the following happens: > Traveler starts at A, jumps the wormhole to point B and immediately jumps back to A, arriving 10 seconds after leaving A. The observer would see: > Traveler starts at A, arrives back at A + 10 seconds and a while later, they are seen exiting and entering the wormhole at B while also being visible at A (Assuming they didn't do anything after exiting there)
