Tme Travel

In the movie Primer two friends unknowingly create a machine for time travel.  Upon discovery they use the machine to make money and save a friend’s life.  Time travel is a concept that fascinates humans; the idea to go back and undo mistakes in the past to better your own life  The idea to be able and go back and change events that have occurred in the process undoes who we think we are and makes us capable of taking actions we would never have taken.  The fact that if we make a mistake we can go back and fix it and just keep repeating this cycle till our life is how we want causes us to be capable of actions that we would see as immoral and overall wrong without this ability to undo it as seen by the two friends who bring harm upon themselves and others. Mankind’s biggest wish is to be able to change what is in the past to change the course of their life. However, what makes time travel   such an intriguing concept is what changes in other people’s lives will they be the same or will that one change cause the butterfly effect.  The butterfly effect is the theory that a minor change say stepping on a bug could completely overturn the future.  This concept is extremely popular in science fiction and is common issue in time travel movies.  The ultimate question that is the central conflict within time travel scenarios is can one small difference change the future in drastic ways.
