Have physicists ever consider traveling into the future in order to travel back to the past? I know it sounds crazy, but one of the paradigms for time travel is Godel's closed time loop curve, where time I think is circular rather than linear. Special relativity permits travelers , if they travel at speeds closed the speed of light, to travel into the future. wouldn't travelers looped back into the past eventually as they are heading further and further into the future if time were circular?
