Document Summary
Time travel is possible: what goes on in a time travel story may be a possible pattern of events in four- dimensional space-time with no extra time dimension (4). Lewis uses the example of a boy named tim going into the past to kill his grandfather, but who does not succeed because the assassination is logically impossible, considering his personal time. Important words: compossible, external time, personal time, change. ): (of one thing) compatible or possible in conjunction with another. Personal time: that which occupies a certain role in the pattern of events that comprise one"s life. Change: qualitative difference between temporal parts of something . Ex: the you of the past and the current you. Lewis muses that time travel is possible, and that he will hopefully convince the reader of this through his essay (1) The paradoxes of time travel are oddities, not impossibilities (1) Time travel = relies on discrepancies between time and itself.
