Just for the hell of it this question popped up in my head (watching some sci-fi movie) ...
If you had a time machine which would you prefer?
A: The ability to go back to any point in time in the past and return to the present or the time that you left?
B: The ability to go forward to any point in time in the future and return to the time that you left?
There is no C: both. You could only do one or the other... why?
