- TL;DR Summary
- I am looking for some clarification for was is meant by "if you could travel faster than light you go travel backards in time." It seems to be a pop sci-fi reference.
I am 99.99% sure I am correct but would like some clarification from the other members here. I occasionally read that "if you could travel faster than light you go travel backards in time." This statement does not make sense to me and seems to be a misinterpritation of reality.
I will provide an example, let's say I throw a ball to my left and then instantaneously (FTL) travel several miles away with a telescope and look at myself. As far as I am concerned I would see myself start to throw the ball to my left. This is not time travel per se, it is just a delayed image of what has happened due to the time it takes for the light to travel from my previous spot to where i threw the ball to the spot where I ended up after instantaneous moving away to see myself.
True time travel would allow me to remain at the same location and I could concievably then decide to instead throw the ball right instead of left, thus I have "changed" the present if you like and create a paradox. As far as I am aware this is not theoreticaly possible, is that correct?
