By: Mike McDaniel Science fiction often uses time as a plot device. We live in linear time, one thing happens after another, one thing comes before another, sometimes causing what follows. My recent movie critique on Arrival, somewhat explores that issue. What if time were not linear? What if cause and effect were out the window, and we lived, continually traveling through time, perhaps randomly, perhaps at will? While it’s easy to imagine some of the consequences of such an existence, it’s impossible to imagine them all. We can know with certainty only life would be very different, perhaps unimaginable.
