Interesting is that screenwriters for Flash Gordon in 1950's (West Berlin production) had "Flash" testing a machine which would theoretically allow Flash to travel faster than the speed of light. Dale quips,(summary) "'ll be travelling so fast that you'll be arriving before leaving."
What physics principle were the screenwriters incorporating in that segment?
Thank you.
See this thread for a discussion of why, in relativity, faster-than-light travel opens up the possibility of sending information backwards in time (although it does not mean that the FTL object itself is going back in time in any absolute sense).
