Andrew Lazarow PHI 107 5/8/11 Is It Possible To Travel Into The Past? Throughout my life I have seen many movies which have a plot centered on the idea of time travel. Clearly, many people have thought about and even tried to justify the idea that time travel is possible. Although as far as we know no human has been able to time travel yet, many people believe that it is definitely possible. Time travel is “the discrepancy between time and time (Lewis, 1976).” When one time does not equal the other time then time has been traveled. For time to not equal time there must be two different types of time. One type of time is external time which is what we see as days and years. The other type of time is personal time. Personal time would be how a person physically matures; how a person goes from being a young kid to an adult. It is when personal time and external time do not equal each other that time travel has occurred. This concept may sound full proof, but there are many contradictions that occur once a person travels back into the external time. One of these contradictions is casual loops. Casual loops occur when “each event on a loop has a causal explanation, being caused by events elsewhere on the loop (Lewis, 1976).” An example of this would be Sam. Sam was told how to invent a time machine by his future self.
