Speed of light and time travel

[Drakkith]

I'm not limiting to traveling FTL. What I meant was, is it impossible to travel back in time, using whatever method at our disposal? so, all those movies about traveling back in time are... you know, just movies, impossible to implement in real world, no method exists to enable us to travel back in time.

To the absolute best of our knowledge, yes, it is impossible to travel backwards in time.
