Take the 2-minute tour ×  I guess this is more a question about
the nature of time travel more than anything else.  At the end
of the movie, Joe shoots himself in a field and changes the
course of history. What I'm curious about is how Joe ended up in
the field given the change in history.  If his future self had
never existed he'd never have gone on the mission he did and
thus he never would have ended up in the field. It seems as
though once he'd killed himself, he couldn't have killed himself
because what led to that event was the existence of his future
self. So theoretically, time and space should have just folded
in on itself and popped out of existence.  What do you think? Is
there something I'm missing that would explain a dead Joe in a
cornfield and how we would have ended up there without their
having been a future version of himself to try and stop?
