The time travel paradox
Time travel as movie concept is sexy. That much is true.
The point of time travel is to change (or not to change) the past, and who doesn't have that fantasy in one form or another.
But travel to the past creates the paradox: that changes to the past could evisciate the present. This leads time travel stories to invent ever more complicated mechanics to explain away the paradox.
However, I can't remember ever seeing a story that deals with the second simpliest solution (The simplest being that time travel to the past is imposible): that there can be no inconsistency since the past aready includes all of the incursions ever made into it. This then creates a new paradox: that the future therefore is predetermined, and cannot be changed either. This then evisciates free will.
Does anyone know of a story that wrestles with this?
