Main Question or Discussion Point
This is my first post, so if I am in any way out of line for the the norm on this site please forgive and instruct me. That said, I found this site while trying to comprehend a physics issue I just cannot seem to get my head around. That would be the claim that faster than light travel woudl violate causality. I understand the concept that if one were able to go back in time, one could theoretically do things which placed the effect before the cause. What I am having trouble understanding is why going faster than light would allow one to travel backwards in time. I have read several articles on the subject, and do not feel I am any closer to a solution. I would be most thankful if someone could help to clear up this tricky concept for me.
