The ability to jump forward and backwards in time has long fascinated science fiction writers and physicists alike. So is it really possible to travel into the past and the future?

    In our universe there are several possibilities to slow the passage of time compared to an observer on earth. Namely travelling at a high percentage of the speed of light or existing in a high gravity field (close to the event horizon of a black hole) but there is no practical way to travel back and forwards in time

    In your SF universe? Well, it is what ever you decide.
